Caleb’s video editing is really bringing some fun into your videos. Really enjoying having your brother in the videos lately. You all are awesome. Thanks for what you do.
Paul, thank you and your brother for this. As TH-camrs we need to share this sort of thing, not only to help each other in the industry, but to inform customers of just how important it is to understand that diagnostics involve work, which needs to be paid for. It is not simply hooking up a scan tool and the tool telling us the part that failed. Unfortunately, many people still think that is the case. I for one always wonder where this idea came from. At no time has it ever been that way. Good on you and Danner. You guys are a huge asset to this industry. God Bless. Oh, and I caught the fact that your son made you 5 feet tall in the mugshot lolol
I know where some people get their bad ideas about diagnostics from. I've met too many people who love to just make arrogant and ignorant assumptions based on second hand nuggets of information they barely paid any attention to. My personal favorite is all the ads for pocket code readers and phone apps where people can read their own codes and suddenly think they know more than they do. The ads are always the same. It's Suzie Homemaker secretly plugs her dongle in and opens the app and reads her O2 sensor code. And then she goes to a shop to have it diagnosed and, miraculously, she's just saved herself from getting ripped off for thousands of dollars because they said she needed catalytic converters but her app just said O2 sensors. The one that makes me cringe most is the kids at the auto parts stores who pull codes for their customers. I've personally heard it where a counter guy pulled codes and said, "Well there you go; you have cam and crank sensor codes, so you need new cam and crank sensors." Admit it, you needed one more thing to roll your eyes at today.
@@shauno3697 you've hit the nail on the head there! I've seen too many tacky adverts where they'll have someone plugging an overpriced generic Bluetooth OBD2 code reader in and then claim the mechanic is ripping them off. They're atrocious and I can only imagine it will lead to a whole lot of difficult customers. If I was on the receiving end of that I'd simply say I have every confidence in them doing the job themselves and saving even more. They'll either have a chance of getting lucky, return with tail between their legs or go somewhere else to avoid embarrassment (and hopefully with an attitude adjustment).
THANK YOU GUYS !!!!! Just fixed my daughter 06 Pontiac G6 by repairing that same terminal connection. Same issues, intermittent starting problems, TC light was on, hard shifting, mass air flow code……All is good now. I never would have found it.
I have been going nuts over this same issue!! We thought it was the ignition lock cylinder, as it would just pull out of the switch because it had been drilled out. I have checked alternator, starter, I’ve went down so many rabbit holes in forums trying to figure it out. I’m going to check that ground tonight to see if it is the whole problem. We had a mechanic over last night who said we were getting the mass air sensor and the air intake temp sensor were throwing codes. The traction control wasn’t working and we have codes for the transmission as well. It even went into limp mode last night after changing the ignition switch. I will definitely check back to let you know if this fixes it!!! There are so many people that have had these same issues with these cars.
Thank you guys for this video. I have been chasing a no communication problem with my 2007 G6. I replaced the PCM and that didn't work either so I found this video and THIS WAS MY EXACT PROBLEM, car is now fixed and gone. FYI this happened after the Transmission was replaced.
Many years ago I did a head gasket job. A couple of months later customer (?) goes to another shop. Shop owner called me on how could I do all that work and not replace plug wires.( her new problem). I asked him if he would like to discuss it in person. I proceeded to bring a copy of her receipt showing her decline of new spark plug wires. discussion and apology over. I never bad mouth any other shop. 2 sides to every story.

I'm glad that you showed the wiring diagram at the end showing how many things are affected bad the single ground connection. It showed exactly what I had found this afternoon. Mine started with a MAF sensor fault. Checked the sensor plug feed wire and had 12v. checked the plug ground wire and had a bad reading for the ground. While tracing the black/white wire and unwrapping the wires, I was hearing the door lock relay clicking in the fuse box as I squeezed the wire loom near the battery. I ended up figuring out that the exact same group of ground wires that you refer to were the cause of the door lock noise and just as yours did, the entire set of wires popped out of the eyelet without any effort. I only came across your video this evening after the fact. Sure wish I would have seen it first. Great catch and it's nice to know how many of these bad ground connections that you have come across. Keep up the good work.
Thank You, Thank You, Thank You I was having problems with erratic door locks and Trans not shifting on my 2006 G6 & this helped me fix the problem Thanks again keep up the good work
Mug shot...awesome. I love that you include us "customers". Even that I've been able to keep up on my own maintenance (with help from channels like yours) I like being an educated customer too.
Marine wiring does not recommend solder connections because of the type of failure you saw here. Since the soldered wires are very stiff, all the stress is taken on the individual strands where they leave the solder. A plain crimp is actually less prone to failure.
Thank you Paul Danner also a big thanks to James and Caleb. This is absolutely invaluable information for me as a DIYer and a Chevy owner.

Awesome work guys thank you again from the community!!!!!
All good info. I am 96 now l have repaired many cars with ground issues, British cars in the 60s and 70s had many of these problems. I went to a local garage where they had an issue with an Austin mini Cooper 1966. They had changed the battery, dynamo starter motor and voltage control and cutout unit. The car wouldn't start, turning over very slowly,as if it had a nearly flat battery. I traced it to a bad ground in the engine ground to the chassis put a new ground cable in. All the parts they had replaced where ok, Looks like they change parts then have to get some one like me to fix it. That was 48 yrs ago, and k am still fixing faults people keep asking me to fix their cars as the garages tend to rip them off
Thank you so much for posting this! I've had the same problems. Fixed the same one you showed and the car started. Still won't start after it's at temp, but I think that's due to burnt wires in the fuse box connections. Fingers crossed I finally figured it out!
This ground issue emphasizes the importance of obtaining complete information from the operator, because a defective ground can cause seemingly unrelated problems, but as you well know, the problems are related to that bad ground. Another excellent video! Keep up the great work!
Thanks for solving my intermittent code problem! All car companies know about their engineering ( faux pas) but it works for the warranty period which is good to go out of the factory door!
You guys did a great discussion on the Pontiac as the ground was not fitted properly obviously. And who would have figured that out. Thank you for sharing.
Paul, you are GOD to me. I have been watching your videos. I have gained so much knowledge just from ur videos that i have now set up my own institute and workshop as well. It has been possible bcoz of u paul. I did not get any training. Jus with the help of ur videos i have come this far. Thank u soooo much
OMG the sweat rag was hilarious!!! Wow it’s been a while since I dropped by but holy cow Caleb has a definite career qualification in video editing. It’s a blast seeing how he just gets better and better and better! I think I am going to have to bingewatch this thanksgiving weekend and catch up on the last couple years!! Happy Thanksgiving Danner Family!!
G6, gm in general, cheap crappy wires, run in really hot places. Bad. Nightmare for average diy people. Thanks for the very helpful video guys. Truly appreciate your work and sharing this very valuable information!!
This video has to have had saved a lot of people i imagine! I fixed some parts and started getting a no com tcm code. I had the car sitting swearing i messed something up and needed a new starteror comp or tcm. Seen this video checked all grounds to the old g6 and the ground had plastic and corrosion covering the inside even though the outside looked not too bad
Great video Danner!. But I need to add something important. On testing bad or weak grounds, it's much better to do the LOAD test than using resistance measurements or voltage drop. Case in point. I just had a 08 Chevy Silverado. Symptoms were intermittent engine shutoff. While driving, the truck wound run fine, but when they turned the A/C on (Loading the ground), the engine would die. I used an old incandescent 4.5 Amp headlight as test light to load the grounds one by one while the engine was on, and when I loaded one of the grounds going to one relay, the engine would would shut off. I found that the bolt holding the bad ground to the engine came loose. The customer said the engine was swapped recently. On a loose ground the resistance measurement and the voltage drop would show an OK ground, because the ground eyelet was barely touching, but when you loaded the ground with a high amp source, the barely touching ground would break. Old headlight lamps as test lights work much better in these situations. Keep up the good work!
Yup. At my shop we've got a seasoned tech that was getting 12v to an actuator but when he'd activate the circuit nothing would happen. I gave him my 35w work light off of a tractor with some leads on it and told him to plug it into the connector. When he'd activate it, it would give a very dim light. Told him he had a corroded joint somewhere. He got to digging and found a corroded fuse terminal. He immediately went and bought himself a light for cases like that.
@@chekelley6861 Yes. It gets loaded....somewhat, but it needs a HEAVY load, like a compressor magnet or a headlight to really stress the connection to test. When grounds are loaded with a high amperage, faulty or weak grounds become apparent more readily. And sometimes you need to test the grounds and other connections with the key off.
@@cyberslacker5150 Actually, the proper way to test a circuit is in the system with the components in place as it was designed by the engineers and measured with a scope or DVOM. Will a substitute load work in most cases? Yes. Is it commonly seen all over TH-cam by famous diagnostic technicians? Yes. But you can make any circuit look bad if you load it beyond what it’s designed to do. Watching how bright a headlight bulb gets is entirely subjective. Using the existing loads combined with an actual measurement never lies.
I wish I had a dollar for every electrical problem I've encountered that turned out to be a bad ground! Usually after I exhausted every other possibility! With 60 years experience, I could probably write a book.
You guys are right. I grew up from 12 working on cars. My godfather had a shop and he took me in when my uncle died. Showed me how to no throw parts at cars or trucks. Find the real problem fix it. Do not ever put a part on car or that don’t need it.
They have a lot of fun with the brothers, they make the job more fun, the three of them make a good team, thanks for the teaching and the entertainment, make more videos together, thank you !!!
With Chevy Cobalt's and Pontiac G5's that have those problems I simply run a 12 gauge wire from the ECM and TCM to the ground location that's on the jump ground point. Tends to fix many electrical issues.
Thanks guys for sharing what you found. Good information to not only look at the grounds but take a voltage reading at the same time to make sure their is no voltage on the ground. Voltage on ground bad. Stay well and safe 😊🇺🇸
Scanner, I had that same problem with my daughters 2008 g6. The car would idle up and down but run ok out on the road. I found a few real thin gauge ground wires that i had to fix in that wire harness going across with the coolant tubes by the dipstick. The ground clip that you showed was corroded so i cleaned up and soldered it all and that's what the problem was.
Great video and specially having your brother there with all his experience too. The rag thing was pretty funny. I had the same problem on a 2000 Dodge Durango and I didn’t realize it was a bad ground. I just cut the wire to the exam and hooked it straight to ground. The car started in any gear since it bypassed the safety switch. I didn’t care, but now I would know how to fix it correctly. Thanks for the great tip.
G6 was a quality car, it had to been because it cost more than a Bentley in the 4 years I owned one. I had that ground problem too!! That was also fun to find, then a week later the water pump quit. AND after that the rad support rotted out..... replacing suspension parts every 7 months.... rust.... trans cooler lines.... bla bla, you get the idea
Paul I am sure you have heard 100 times that you two dont look like brothers... but you sure act like brothers :) You 2 keep up the great work ! Thanks to you and Ivan at Pine hallow and SMA .. I was able to fix as friends no crank problem caused by a low cost immobilizer... I had to bypass the bypass :) .. Bu it now works with a key on and press a starter button
Hey Paul I just came across one of these tonight, or a 06 Cobalt. Had a Crank No Start with a U0101 no com to transmission control module. It was Ground 105. I just put up a quick video on it. Same exact thing. All the wires broke inside, but still crimped on.
I just came across your video about 2 months too late. I had an 09 Saturn Aura that I bought back in 2010. I drove it for 280K miles, always ran great but one day I got what felt like a hard shift, lost my speedometer and a few other funky electrical issues. Pulled the car over shut it off but when I went to restart it got it wouldn't even crank. I put my basic scan tool on it and it said it couldn't communicate with the TCM. I did check for bad grounds but now I'm not certain if I looked hard enough. Replacing the TCM (part was only about $200) was going to involve pulling the tranny and disassembling it so I ended up junking the car. I hope I didn't get rid of it because of a ground issue. Bums me out, that car would have easily gone another 100K miles.
Man i miss Saturn's! I had 4 different Saturn's every single one of them made it to 300,000 + miles on them when I sold them and always saw them back out on the road STILL GOING! I've not owned another car besides those that made it even to 150,000 before something major, usually transmission issues started up. I swear that's why they went out of business, they were just 2 Good!
You are welcome daner has a video on how he got started and its got some good information every one starts some where if you show interest and let the techs know u want to learn the should help you learn i spent 6 years doing a 4 year apprenticeship 30 year's ago and I still learn stuff every day .
Ground again, and all by the book, Paul, it gets easier once you learn the basic things, like ground in this case, doesn't it? Good job, Danner's team. Can't stop watching you guys, it is so useful.
@@ScannerDanner I bet you get them a lot every day, you do a big job over there, Paul, filming and teaching new generation of mechanics. Don't stop, please. Looking forward to seeing newer vehicles too.
@@ScannerDanner You saved me testing the park/neutral and then trying to figure out where the ground was supposed to originate in the first place. If I encounter an expensive repair, the car is going to be donated. You've helped postpone that
My Pontiac is having this same issue. I just changed the starter and still nothing. When I turn the car on everything works but won’t cut but after a couple hours it starts fine
Thanks for the info... got similar issues and I replaced battery and looked and tested starter. This could be the culprit. I'll let you know later if it works.
This grounding issue reminds me of a problem with early model V6 Nissan Pathfinders, Frontiers, and Xterras. A bad ground terminal on the aluminum upper intake manifold can cause multiple trouble codes regarding O2 sensors. The service bulletin says that if the ground terminal is more than 25mV with a warm engine at idle, then a new ground wire should be installed. Fortunately, the terminal is easy to access.
Toyota Siennas have ground wires attached to each bank. One easily accessible on the right side when facing the engine and the other one not visible from the front but from the bottom. In my case I had heating circuits for the O2 sensors for both banks, these are shared, there are least 4 ground wires that are directly fed to the PCM that is used for grounding components, in this case the O2 sensors, the ground wires were toast and ripped off as soon as I touched it. I diagnosed this by watching the pulse width from the computer that was not present, I almost called the engine computer but I didn't realize the the computer had so many small ground wires. I guess Toyota doesnt have many shared ground internally as we are used to. This was a Toyota Sienna 2012.
Just fixed another one of these on a g6. It had been to 2 shops and one other mechanic said it need a new PCM. They called me to program replacement PCM. I knew what the problem was as soon as I arrived. Cleaned the wires, crimped on a new lug and hooked it back up and it was fixed. The customer didn't want to pay me my 85 for the diag and 50 for the labor. It told them that's fine. I can break it again, and grabbed my wire cutters, they were like no, no.. We will pay.
Oh my, I just dealt with this. SAME THING. I was so busy and I gave my 96 Explorer into the Ford place for an oil change. $20 special :lol:. Well they did a complimentary check on the car and said your 4x4 low don't work, we suggest a new shift motor. Get an estimate for $500. He pointed to a newer F-150 and said same problem, we just replaced one under warranty. Ok, I take it home, hook up the scanner. No relay click when I put it in N, press brake and 4x4 low. Scanner don't show Neutral pid changing. Looking up wiring. GEM uses trans switch to verify neutral. Ford has a special redundant switch on that trans switch for 4x4. Two circuits to verify neutral. Hot side ok GEM to trans switch. Ground side- GEM computer -> wire breaks out of harness near the firewall -> goes into the SPADE CRIMP IN THE VIDEO- on a ground stud.>Another wire is in that crimp. Goes back in harness, goes back down to a pin on the trans switch. You see the rest. wires in the crimp rotted out. Open ckt from GEM to that pin. New connector,15min later, works as good as new. Cost me 20cents in materials. So someone would pay Ford $500, come back, and they would probably throw a trans switch at it too, maybe a relay module.. then probably tell them its time to trade :lol: . Thinking of going back and confronting them :lol:
Hey Paul Work on standby power. Generators for those that don't know. The point. When performing PM's the ground(s) get special attention. It's simple enough to fully disassemble clean and reassemble. If you think people get excited about their vehicles not functioning. What till their standby power fails!
great video, I have the same car my horn stopped working ended up being the relay after I took the time to install a new horn and still didn't work. lol. I'm going to check my grounds now thanks for the information.
I once had a customer bring a van in for the blower not working. He said it had been working fine until the day before. Test light confirmed voltage to the blower. Test light also confirmed voltage at the ground strap from the blower to the fender ;-) The screw in the fender was screwed into bondo.... I called and asked if the van had ever been wrecked. The customer said, sure six years ago........... Sometimes the customer's info helps. Sometimes not.
I did the pulls on those connectors, and for a while, it started fine. Then, from the time of this comment, I'm sitting in the parking lot with the same issue. No start... I replaced both connectors. Update I found more of those bad connections replaced all of them it started.
Loved it, Thanks for sharing SD👍 Indeed the basic thing that you always teach us to be mindful of "Check your Grounds" but this one was really difficult to diagnose if not measured properly😉 Stay Safe Brothers❤
@@ScannerDanner I was chasing a intermittent stumble for a month. Random just acts like you shut the key off and back on. Then no maf sensor. G105 is ecu ground and maf ground.
Hey my friend :) Maaaan ..Danners beard is massive!!!Awesome :) And so is this video.Love these videos that shows how important the basics are....Check grounds and feeds...Always. Thank you once again ,and i also hope you all are doing great :) Greetings from the NorwegianWiringViking, Stefan :)
I have no sympathy for customers. When I hire stuff out, I look for the best in the business. If you want to be cheap and not pay a diagnostic charge, its on you. In the end, the best guy is usually actually very reasonably priced (if not cheaper) compared to the other clowns in town.
So if it’s the ground how come it takes 8 hours to start again shouldn’t it just not start at all I’m having the same issue where it will start in the morning and I cut it off and I have to wait hours for it to start again
thanks for telling me a while back signing up to the premium site would help me well wanted to say more than i could have ever expected thanks for your hard work
While i remember this Toyota pick up 35 years ago I worked on Bad ground Battery , alternator And the Volt regulator on the engine firewall . Would all be great for a 20 min drive . Was the day i learned about the notorious toyota block grounding issue 🤣🤣🤣
Love the vid, you two are awesome :) Now can you show exactly where the grounds were I can probably find the one on the transmission. My goal is to redo them all... Love u guys :) I am just going to solder more wire then just put on bottom of bolt or connector until I find a better ground solution.

This ground issue emphasizes the importance of obtaining complete information from the operator, because a defective ground can cause seemingly unrelated problems, but as you well know, the problems are related to that bad ground. Another excellent video! Keep up the great work!
Thanks for solving my intermittent code problem! All car companies know about their engineering ( faux pas) but it works for the warranty period which is good to go out of the factory door!
You guys did a great discussion on the Pontiac as the ground was not fitted properly obviously.
And who would have figured that out.
Thank you for sharing.
Paul, you are GOD to me. I have been watching your videos. I have gained so much knowledge just from ur videos that i have now set up my own institute and workshop as well. It has been possible bcoz of u paul. I did not get any training. Jus with the help of ur videos i have come this far. Thank u soooo much
So awesome to hear. Thank you!
I started crying when your brother used your sweat rag... his reaction, priceless!
My G6 experienced the same problem. The connection “looked” good, but meters don’t lie. Thanks for the help!
OMG the sweat rag was hilarious!!! Wow it’s been a while since I dropped by but holy cow Caleb has a definite career qualification in video editing. It’s a blast seeing how he just gets better and better and better! I think I am going to have to bingewatch this thanksgiving weekend and catch up on the last couple years!! Happy Thanksgiving Danner Family!!
My man! Glad you enjoyed it and thanks again for the phone call last night my friend. Happy Thanksgiving!
pro trick: you can watch series on KaldroStream. Been using them for watching all kinds of movies recently.
@Damian Melvin Yea, I've been watching on Kaldrostream for years myself :D
G6, gm in general, cheap crappy wires, run in really hot places. Bad. Nightmare for average diy people. Thanks for the very helpful video guys. Truly appreciate your work and sharing this very valuable information!!
This video has to have had saved a lot of people i imagine! I fixed some parts and started getting a no com tcm code. I had the car sitting swearing i messed something up and needed a new starteror comp or tcm. Seen this video checked all grounds to the old g6 and the ground had plastic and corrosion covering the inside even though the outside looked not too bad
Great tip! Knowing common faults can save a lot of time. Loading that ground with 20-30A might be a good way to confirm it was bad. Thanks.
Thanks a lot team Danner, your videos are always fun, a big hug.
Great video Danner!. But I need to add something important. On testing bad or weak grounds, it's much better to do the LOAD test than using resistance measurements or voltage drop. Case in point. I just had a 08 Chevy Silverado. Symptoms were intermittent engine shutoff. While driving, the truck wound run fine, but when they turned the A/C on (Loading the ground), the engine would die. I used an old incandescent 4.5 Amp headlight as test light to load the grounds one by one while the engine was on, and when I loaded one of the grounds going to one relay, the engine would would shut off. I found that the bolt holding the bad ground to the engine came loose. The customer said the engine was swapped recently. On a loose ground the resistance measurement and the voltage drop would show an OK ground, because the ground eyelet was barely touching, but when you loaded the ground with a high amp source, the barely touching ground would break. Old headlight lamps as test lights work much better in these situations. Keep up the good work!
Yup. At my shop we've got a seasoned tech that was getting 12v to an actuator but when he'd activate the circuit nothing would happen. I gave him my 35w work light off of a tractor with some leads on it and told him to plug it into the connector. When he'd activate it, it would give a very dim light. Told him he had a corroded joint somewhere. He got to digging and found a corroded fuse terminal. He immediately went and bought himself a light for cases like that.
G105 is loaded as soon as the key is on lol
@@chekelley6861 Yes. It gets loaded....somewhat, but it needs a HEAVY load, like a compressor magnet or a headlight to really stress the connection to test. When grounds are loaded with a high amperage, faulty or weak grounds become apparent more readily. And sometimes you need to test the grounds and other connections with the key off.
@@cyberslacker5150 Actually, the proper way to test a circuit is in the system with the components in place as it was designed by the engineers and measured with a scope or DVOM. Will a substitute load work in most cases? Yes. Is it commonly seen all over TH-cam by famous diagnostic technicians? Yes. But you can make any circuit look bad if you load it beyond what it’s designed to do. Watching how bright a headlight bulb gets is entirely subjective. Using the existing loads combined with an actual measurement never lies.
I wish I had a dollar for every electrical problem I've encountered that turned out to be a bad ground! Usually after I exhausted every other possibility! With 60 years experience, I could probably write a book.
You guys are right. I grew up from 12 working on cars. My godfather had a shop and he took me in when my uncle died. Showed me how to no throw parts at cars or trucks. Find the real problem fix it. Do not ever put a part on car or that don’t need it.
They have a lot of fun with the brothers, they make the job more fun, the three of them make a good team, thanks for the teaching and the entertainment, make more videos together, thank you !!!
With Chevy Cobalt's and Pontiac G5's that have those problems I simply run a 12 gauge wire from the ECM and TCM to the ground location that's on the jump ground point. Tends to fix many electrical issues.
Thanks guys for sharing what you found. Good information to not only look at the grounds but take a voltage reading at the same time to make sure their is no voltage on the ground. Voltage on ground bad. Stay well and safe 😊🇺🇸
Scanner, I had that same problem with my daughters 2008 g6. The car would idle up and down but run ok out on the road. I found a few real thin gauge ground wires that i had to fix in that wire harness going across with the coolant tubes by the dipstick. The ground clip that you showed was corroded so i cleaned up and soldered it all and that's what the problem was.
Thanks Paul and brother, Caleb. Good job...
Great video and specially having your brother there with all his experience too. The rag thing was pretty funny. I had the same problem on a 2000 Dodge Durango and I didn’t realize it was a bad ground. I just cut the wire to the exam and hooked it straight to ground. The car started in any gear since it bypassed the safety switch. I didn’t care, but now I would know how to fix it correctly. Thanks for the great tip.
G6 was a quality car, it had to been because it cost more than a Bentley in the 4 years I owned one. I had that ground problem too!! That was also fun to find, then a week later the water pump quit. AND after that the rad support rotted out..... replacing suspension parts every 7 months.... rust.... trans cooler lines.... bla bla, you get the idea
Paul I am sure you have heard 100 times that you two dont look like brothers... but you sure act like brothers :)
You 2 keep up the great work ! Thanks to you and Ivan at Pine hallow and SMA .. I was able to fix as friends no crank problem caused by a low cost immobilizer... I had to bypass the bypass :) .. Bu it now works with a key on and press a starter button
I like the way these guys dont put other shops or people down
Excellent view, high quality camera
Hey Paul I just came across one of these tonight, or a 06 Cobalt. Had a Crank No Start with a U0101 no com to transmission control module. It was Ground 105. I just put up a quick video on it. Same exact thing. All the wires broke inside, but still crimped on.
I just came across your video about 2 months too late. I had an 09 Saturn Aura that I bought back in 2010. I drove it for 280K miles, always ran great but one day I got what felt like a hard shift, lost my speedometer and a few other funky electrical issues. Pulled the car over shut it off but when I went to restart it got it wouldn't even crank. I put my basic scan tool on it and it said it couldn't communicate with the TCM. I did check for bad grounds but now I'm not certain if I looked hard enough. Replacing the TCM (part was only about $200) was going to involve pulling the tranny and disassembling it so I ended up junking the car. I hope I didn't get rid of it because of a ground issue. Bums me out, that car would have easily gone another 100K miles.
Man i miss Saturn's! I had 4 different Saturn's every single one of them made it to 300,000 + miles on them when I sold them and always saw them back out on the road STILL GOING! I've not owned another car besides those that made it even to 150,000 before something major, usually transmission issues started up. I swear that's why they went out of business, they were just 2 Good!
You are welcome daner has a video on how he got started and its got some good information every one starts some where if you show interest and let the techs know u want to learn the should help you learn i spent 6 years doing a 4 year apprenticeship 30 year's ago and I still learn stuff every day .
Ground again, and all by the book, Paul, it gets easier once you learn the basic things, like ground in this case, doesn't it? Good job, Danner's team. Can't stop watching you guys, it is so useful.
Thanks so much!
Watching now premium channel, won't go to bed soon, very good material to learn and to prepare for the Red seal exam, same as ASE I believe.
@@alexturov3612 thank you! I look forward to hearing from you. It's touch to keep up but I try to answer as many questions as I can for you guys.
@@ScannerDanner I bet you get them a lot every day, you do a big job over there, Paul, filming and teaching new generation of mechanics. Don't stop, please. Looking forward to seeing newer vehicles too.
Thanks!
This is completely unexpected but much appreciated! Thank you!
@@ScannerDanner You saved me testing the park/neutral and then trying to figure out where the ground was supposed to originate in the first place. If I encounter an expensive repair, the car is going to be donated. You've helped postpone that
My Pontiac is having this same issue. I just changed the starter and still nothing. When I turn the car on everything works but won’t cut but after a couple hours it starts fine
Mine too!! We are going to try this!
Thanks for the info... got similar issues and I replaced battery and looked and tested starter. This could be the culprit. I'll let you know later if it works.
This grounding issue reminds me of a problem with early model V6 Nissan Pathfinders, Frontiers, and Xterras. A bad ground terminal on the aluminum upper intake manifold can cause multiple trouble codes regarding O2 sensors. The service bulletin says that if the ground terminal is more than 25mV with a warm engine at idle, then a new ground wire should be installed. Fortunately, the terminal is easy to access.
Toyota Siennas have ground wires attached to each bank. One easily accessible on the right side when facing the engine and the other one not visible from the front but from the bottom. In my case I had heating circuits for the O2 sensors for both banks, these are shared, there are least 4 ground wires that are directly fed to the PCM that is used for grounding components, in this case the O2 sensors, the ground wires were toast and ripped off as soon as I touched it. I diagnosed this by watching the pulse width from the computer that was not present, I almost called the engine computer but I didn't realize the the computer had so many small ground wires. I guess Toyota doesnt have many shared ground internally as we are used to. This was a Toyota Sienna 2012.
Just fixed another one of these on a g6. It had been to 2 shops and one other mechanic said it need a new PCM. They called me to program replacement PCM. I knew what the problem was as soon as I arrived. Cleaned the wires, crimped on a new lug and hooked it back up and it was fixed. The customer didn't want to pay me my 85 for the diag and 50 for the labor. It told them that's fine. I can break it again, and grabbed my wire cutters, they were like no, no.. We will pay.
People suck man. Two different shops and you fixed it and they didn't want to pay? And your prices are cheap too!
Smh
Nice job my friend
Top danner, danner very good Video. Thanks for your Videos. All good for you and your danner, danner Family.
Oh my, I just dealt with this. SAME THING. I was so busy and I gave my 96 Explorer into the Ford place for an oil change. $20 special :lol:. Well they did a complimentary check on the car and said your 4x4 low don't work, we suggest a new shift motor. Get an estimate for $500. He pointed to a newer F-150 and said same problem, we just replaced one under warranty.
Ok, I take it home, hook up the scanner. No relay click when I put it in N, press brake and 4x4 low. Scanner don't show Neutral pid changing. Looking up wiring. GEM uses trans switch to verify neutral. Ford has a special redundant switch on that trans switch for 4x4. Two circuits to verify neutral. Hot side ok GEM to trans switch. Ground side- GEM computer -> wire breaks out of harness near the firewall -> goes into the SPADE CRIMP IN THE VIDEO- on a ground stud.>Another wire is in that crimp. Goes back in harness, goes back down to a pin on the trans switch. You see the rest. wires in the crimp rotted out. Open ckt from GEM to that pin. New connector,15min later, works as good as new. Cost me 20cents in materials.
So someone would pay Ford $500, come back, and they would probably throw a trans switch at it too, maybe a relay module.. then probably tell them its time to trade :lol: . Thinking of going back and confronting them :lol:
When Danner said customer states: "Horn doesn't work but I don't care about that". 🤣
He said that it's unrelated (issue).
It is probably code for the lady to indicate to Danner that even though he's ugly, she still wants to cozy up to him.
Hey Paul
Work on standby power. Generators for those that don't know. The point. When performing PM's the ground(s) get special attention. It's simple enough to fully disassemble clean and reassemble. If you think people get excited about their vehicles not functioning. What till their standby power fails!
great video,
I have the same car my horn stopped working ended up being the relay after I took the time to install a new horn and still didn't work. lol.
I'm going to check my grounds now thanks for the information.
Excellent video once again! Thanks for sharing. The shop towel ending is priceless.
Thanks a lot!!! I had the same exact problem ground wire was broken didn’t look like it I pulled it fell right off
I once had a customer bring a van in for the blower not working. He said it had been working fine until the day before. Test light confirmed voltage to the blower. Test light also confirmed voltage at the ground strap from the blower to the fender ;-) The screw in the fender was screwed into bondo.... I called and asked if the van had ever been wrecked. The customer said, sure six years ago........... Sometimes the customer's info helps. Sometimes not.
😀😀😀😀😀great video Sanner Danner , and thanks for teaching🙏 saludos for big brother and camera man 📷 son Caleb
Got the same clock in my shop! Live to ride Ride to live! Great video Paul!
I did the pulls on those connectors, and for a while, it started fine. Then, from the time of this comment, I'm sitting in the parking lot with the same issue. No start... I replaced both connectors. Update I found more of those bad connections replaced all of them it started.
Most wanted. Auto technician 🔧🚘
Thank you Danners' cubed. Good job again. Have a blessed and safe week to you and your families.
Danners cubed 😂
Loved it, Thanks for sharing SD👍
Indeed the basic thing that you always teach us to be mindful of "Check your Grounds" but this one was really difficult to diagnose if not measured properly😉
Stay Safe Brothers❤
Omg thank you. This just fixed my g6. Bad g105 ground.
Glad I could help! This car had thousands of unnecessary repairs done for this issue
@@ScannerDanner I was chasing a intermittent stumble for a month. Random just acts like you shut the key off and back on. Then no maf sensor. G105 is ecu ground and maf ground.

Hey my friend :) Maaaan ..Danners beard is massive!!!Awesome :) And so is this video.Love these videos that shows how important the basics are....Check grounds and feeds...Always. Thank you once again ,and i also hope you all are doing great :) Greetings from the NorwegianWiringViking, Stefan :)
It’s amazing how many engineering design flaws you see in aircraft also. That ending was hilarious!
Thank you for pointing out you were not there at the other shop so you can only speculate what may have happened based on the owner's story.
Please do a live repair video ,thanks !
Great vid I Looooved the end “did you wipe your face with that ?” 🤣🤣🤣👍
I have no sympathy for customers. When I hire stuff out, I look for the best in the business. If you want to be cheap and not pay a diagnostic charge, its on you. In the end, the best guy is usually actually very reasonably priced (if not cheaper) compared to the other clowns in town.
You guys are the best stay safe
Thank you, thank you, thank you. Kept getting an error message. No crank, no start.
Nice! Same issue with yours i take it?
Another amazing video lots of love and blessings from Pakistan
Zindabad
I wish I wasnt on the wrong side of the state. I would love to be able take my cars to Danners shop.
Awesome vid, loving the new editing!
Great information, thank you guys, excellent camera were Caleb
Also love the garage respect
I like this content SD
This is a helpful video, thanks for sharing!
Did you relocate the ground? What type of connector did you use to make the repair? Did you solder or crimp the connection ?
So if it’s the ground how come it takes 8 hours to start again shouldn’t it just not start at all I’m having the same issue where it will start in the morning and I cut it off and I have to wait hours for it to start again
Temperature expands and contracts metals.
those dern GM grounds lol , awesome video bro !!!!
thanks for telling me a while back signing up to the premium site would help me well wanted to say more than i could have ever expected thanks for your hard work
Thank you so much!
Only thing better than two Danners is three
While i remember this
Toyota pick up 35 years ago
I worked on
Bad ground
Battery , alternator
And the Volt regulator on the engine firewall .
Would all be great for a 20 min drive .
Was the day i learned about the notorious toyota block grounding issue 🤣🤣🤣
Good catch. Thanks for sharing
Very informative. Great video
Thank you for this video. I'm nursing my 2007 Pontiac G6 GT (hardtop convertible) along until somebody gifts me a Bentley.
I have to agree. Quality it fantastic.
You guys are great. Love your videos.

You will never get away with your crimes because your short height gives you away!
🤣 I'm not 5ft, My son was poking fun at me as usual
LOL It looks like someone's sensitive about his lack of height!
Love the vid, you two are awesome :) Now can you show exactly where the grounds were I can probably find the one on the transmission. My goal is to redo them all... Love u guys :) I am just going to solder more wire then just put on bottom of bolt or connector until I find a better ground solution.
Thanks guys!
