Great job Eric. I've learned the hard way, never assume the parts the previous technician replaced was good. Always start your troubleshooting from scratch.
Agreed, sometimes the biggest mistake you can make is to assume that just because something is new it must work. Sometimes all it means is it isn't rusted in place when you need to change it again.
Yeah, seen too many situations where the brand new part (usually some gibberish-named knockoff from Amazon) was worse than the old one, though in this case the previous "mechanic" simply lied altogether. Hope the Ram guy can get his money back somehow.
I feel like i repeat myself on every one of your videos but ive gotta say it again. You explain whats going on during a diagnosis better then ANYONE on youtube. Explaining the bias voltage from the pcm is using that as a test for the circuit then showing it loaded… 👏 👏 👏. Thats the type of stuff alot of people would skip over or assume alot of people would know. Great stuff as usual brother 👍
You found the problem and fixed it......period! GREAT DIAGNOSIS! If that's a Cummins engine and fan unit, they have a pretty thorough diagnostic test, in some cases you have to know "Cummins Speak" but once you've done one, you'll know! My knowledge is limited and it was over 6 years ago working with a Cummins CNG engine. Fun time!
ERIC, UR truly a technician with integrity and honesty who every one would love to bring his vehicle to you to fix the right way as u did with this one as always AWESOME information and approach thanks for sharing.
Eric, what a fantastic diag! Whew, dodged a bullet not calling it a $4000 computer and being wrong. You always do a great job of thinking things through. Customer should also be thrilled! Thanks again for posting, we have all learned something on how this circuit works.
Hey bro new subscriber from Los Angeles, loving your tenacity to hunt these issues down, I'm a novice car mechanic, only really work on my own cars (BMWs/Chevy 1965). Keep up the great work!!!
I love the way you explain electrial diagrams, it's nice to see people who truly understand them , when I went to vocational school years ago one thing my instructor inculcated into our heads was you need to understand basic electricity and schematics to ever make it in the field, to this day I continually use what I've learned even though I'm not in the business of car repair but I still do it for lots of friends and relatives because there is a lot of mechanics out there who do not understand how to or even repair electrical problems or even do this kind of Diagnostics , I am in the electrical field , I do lots of problem solving that other electricians cannot figure out by the way. Keep up the good work and making the videos that are truly impressive I can not imagine how much time you spend making them, hopefully someday you'll be able to hire your son or (daughter if you have one) to edit them for you like a lot of other TH-camrs and they can make an income also and enjoy doing what they do. Have a great day.
Your the best and honest Eric, Keep up the great work. I am always learning new things from your videos. People these days buy cheap used parts and install them without knowning it could be defective. Being honest and informing the customer of the repair with detail is always the best way to do it.
Thank you sir for this full in-depth diagnostic , I just replaced my clutch fan and after pulling a load of 28k. My truck was doing the same and the diesel shop I went to was doing the same Diagnostics and same tools you have and you have now proved that my pcm is still good and I’ll be getting a different brand
ERIC, YOU ARE A GREAT DIAGNOSTICS TECH AND WELL AWARE OF THE INCOMPLETE OF TECHNICAL DATA PROVIDED TO ALL OF US IN OUR FIELD. YOU DEFINITELY VERIFIED THE ECM IS NOT BAD. CONGRATUALATION ON A JOB WELL DONE.
Another great video, excellent troubleshooting I really enjoy watching you diagnose problems ,the way you explain things is very clear and concise, I'm a retired Master Tech of 40 years and I'm still learning, Great job!
Eric. thank you for a very detailed electrical fix. Among every auto fix, electrical ones are the hardest. you have shown us honestly on your fixing. BTW, I do rant this world a little, you do deserve a shop to help people out.
I'm an old school auto and truck mechanic that enjoys auto diagnoses videos because I hope to learn something about modern vehicles and; by and large, I have. However, one thing that I've heard on other videos by other mechanics before but never understood was the idea of a bias voltage. You, Eric, were the first to actually explain what it is and how, precisely, it is used for auto system control. That was very, very cool! You're a born teacher! Oz is pretty good at it too but I really like how you go out of your way to explain things to us knuckleheads. Much appreciated, sir!
I'm sure the customer learned their lesson and won't take their truck back to that "mechanic" . That harness coming off the fan clutch didn't look new to me.great video
Great video! I misdiagnosed my friend’s car. Her car couldn’t move backward. Thought it was suspension related part or transmission . Turned out brake pad were came loose. Pad material were gone. Rotor was thin! Not an expert in Suspension system… I’m a young tech..so I’m constantly learning! It’s a pain but crazy! You are very honest and I learned a lot from you!
Another great video, thanks for the upload! I love how you still keep your videos real and don't try and bullshit your viewers by editing out the 'mistakes'. It's the 'mistakes' that help us all learn. Also it's so much tougher when the manufacturers don't share important information regarding how a system works or what sort of readings you should expect! Looking forward to your next video!
Awesome job, Eric! That was some first-class diagnostics, there and proof that experience really does make a difference. The experience gives you that instinctual “gut feeling” when something isn’t right.
Absolutely awesome Eric great work, I learned quite a bit and as always when you make a mistake , it stays in your mind and you remember for a long time !!
Thanks for the case study Eric!! What a great feeling you get from almost misdiagnosing a job, but end up rechecking and finding something totally different. A great learning experience! It’s best practice to NEVER assume anything and to test for yourself (even if a part is new or someone already ‘diagnosed’), then recheck if you have an unexpected result. Great work! 👍
I cannot believe how many times technical information called it a clutch fan. A clutch fan, if one really exists would be a device that cools your clutch. A clutch may indeed overheat and be in need of cooling, but I know of no device designed to do so. A fan clutch, on the other hand, would be the proper device to engage the radiator cooling fan. Just one of my pet peavs. Just saying. Great video Eric. Keep 'em coming.
Awesome work Eric. I was out of town working one day when the company truck a 2017 Ram 2500 was having a similar issue where it would heat up and reduce the speed it could be driven when towing a trailer. it was a 16 foot enclosed trailer with maybe 1,500 LBS of extra weight aside from the trailer. should not have been an issue. i towed the trailer with my truck so we could make if to and from the hotel but we finally took a look and there was a small connector in the shape of an L that came from a hose and connected to a pipe that keep breaking. we replaced it with an identical unit and it broke. so we grabbed some fittings from home depot and a hose from autozone and replaced the piece. has worked like a charm since then
I like it, from a retired ASE master! Why, when the service tech uses common sense and finds a problem, it becomes fixed. I don’t like PWM fan clutches but this is the world of lower emissions and higher fuel economy we live in! But you have to verify the customers concern, then following “TSB’s” if any, then diagnose the root cause. Too many repair the symptom and replace a part. Go to the parts store and let them read the current code. Just understand if it says “O2” sensor, does not mean it is bad. Too low for long time, too high for long time, heater open, high resistance because a new exhaust had an O2 wire melt on it. You see, the code only points to the component, but does not diagnose the real reason. Parts stores enjoy selling $170 heated 4 wire O2 sensors, but it may be correctly reporting a problem as say the fuel pressure regulator is dripping raw fuel past a ruptured diaphragm (If Yours Has One) but in this case, the O2 is reporting a rich mixture over a long period of time (Varies by Manufacture) but is fine. Complicated? Yes, blame the Government for CAFE standards, CARB for setting expectations for emissions, EPA for the rules and marketing for noise, safety, and MPG and others like crash testing to set insurance rates. Then how big the city is, number of accidents, deaths, theft as you move into the country 200-300 miles from a big city, your rate can drop 39%. Fact! ASE master tech since 1978.
Another great educational video. Learned a lot from it. Your number one in my book. You a true diagnosis you add teaching in your videos and it helps a lot.
Great job Eric, you are awesome no matter what. Everyone makes honest mistakes and has to clarify errors in their minds. Just shows you care about the quality of what you do. Also shows you are a legit honest mechanic.
Glad to see you back in the field and making videos again. It was a shame to lose your shop but most your work seem s to be on site anyway so no point paying for something that your never at. Love your work and have learnt alot from your videos.
Great video I learned a lot Wish you would’ve showed taking out and putting fan clutch back in. You took your time overall with a customers vehicle and didn’t just do some random ish. Very thorough I’m sure your clientele loves you.
Love your videos. You are truly a great mechanic and system analyzer. Your explanations of complex systems are great. Just wished you were closer to where I live.
Good job. At my job when someone does a repair and the machine is still not working. I check the tech's work first. I've found a few times that they made a mistake.
Great video Eric!! I actually did know about bias voltage… how ever it slipped my mind about Chrysler using it🤷Great job teaching us! We are all human 👍
Long Video. BUT so much helpful info. My old 2005 Dodge 2500 had a similar problem, wasn't to replace the freaking expensive computer. So this explains some of the issues and unknowns i was dealing with. Learned about the load test, so when my buddy replaces the Tranny on my old Dodge I can help him figure it out so he can maybe get that old 5.9 to 750k.
Amazing work eric! Thats a really good point on the biased voltage & that is something that we need to keep in the back of our mind when troubleshooting. Salute to you sir!
Thats a great video Eric and explaining bias voltage and always test and not guess as seen ecu put on cars as they not checked wiring and rule out new parts already fitted that are faulty or been broken when fitted
Eric I really admire your ability to diagnose even though it meant 2nd guessing yourself. I'm here in Tx. as well and just recently started my mobile advanced diagnostics/module programming business. I would love to talk to you and hear how your charging for your services. Let me know if we can chat. Thx David
Awesome. Called possible bias voltage from the 3.9v right away. He should've come to you in the first place. Some people only give me the head scratchers and take the easy jobs to someone else.
congratulations on the diagnosis, I'm Brazilian and I live in Miami. Where can I buy the worshipers you use in the multimeter? Yellow connectors that you stick inside the cables
Hi I’ve just found this channel, & I’m impressed with you contents quality so iv subscribe as I’ve enjoyed it , manny thanks 👍😀 Ps I can’t understand why a manufacturer would put a computer and all the wire plugs in scutch a place where it’s vulnerable to the outside elements being so close to the ground et cetera???
Good save on the explanation at 15:50. When something is PWM, pwr or gnd contl. I Always look at the PWM sig First this can tell me if the controller is actually working and if there is a pwr or gnd error then the check pwr and grd wgile doing BI/D/C of the device. 90/100% should mean full pwr or full gnd else 20% or less is opposite
As usual, great trouble shooting Eric. I’m surprised the PCM is bolted to the engine block. I would have thought a computer would not be so close to a big heat source. It seems modern computers aren’t as sensitive to heat as old ones.
Eres todo un maestro Erick, mis saludos desde Petaluma California me encanta ver tus videos y gracias por cada video que ases para nosotros tus seguidores
I replaced a new head gasket arp head studs rebuilt head and I had electric fans and the truck temperature gets up up to 220 226 I’m thinking to put back the stock fan clutch I have coolant by pass every time when I’m loaded the temperature goes up I think the fans don’t work good with towing
I got a question to ask you ? What would happen you did purchase the ECM $4000 and you installed , and didn’t work what would you do to say to the customer ? I know computer plugged in it’s no return .
Shop I went to assures me that it's the pcm is bad. The fan clutch is new and they ohmed it out and said it was good. They said that the fuse is good. The ac/ transducer was good, wiring and all pins were good and had continuity. They were certain that the computer was bad. But they said they have no way of testing till they put the computer in and if it's not the issue it's on me they can't return the computer. I was about to green light them but then I saw this video and concerned. The fan that is in there is OEM and does not have the connection as shown in this video it is hard wired on the fan side plug. Am I missing anything? It's about $3500 and about 3 weeks till they can get a computer. Any input would be great
Great job Eric. I've learned the hard way, never assume the parts the previous technician replaced was good. Always start your troubleshooting from scratch.

ERIC, YOUR THOUGHTS AND DIAGNOSIS ARE SO LOGICAL AND WELL ORGANIZED BEYOUND WORDS DESCRIPTIONS, THANK A MILLION FOR YOUR EFFORT. RIGHT ON THE MONEY.
Pisses me off to see a customer get jerked around like that on such a simple repair. I'm glad you could help him out.

Awesome job, Eric! That was some first-class diagnostics, there and proof that experience really does make a difference. The experience gives you that instinctual “gut feeling” when something isn’t right.
Today wasn’t a waste I leaned something from this video . Nice work I’m subscribing .
Awesome episode! Glad to see the whole diagnosis process. Big props for your honesty and including the part where you got sidetracked.
Absolutely awesome Eric great work, I learned quite a bit and as always when you make a mistake , it stays in your mind and you remember for a long time !!
Thank you for the thought process. The bias voltage was an eye opener. Good job!

Great job Eric, you are awesome no matter what. Everyone makes honest mistakes and has to clarify errors in their minds. Just shows you care about the quality of what you do. Also shows you are a legit honest mechanic.
Thanks for explaining how the bias voltage is used to verify circuit integrity. Nice work!
It's good to show the human side of things. You got my respect when you worked on that flooded out lexus
You're a terrific mechanic. Good job done.
Glad to see you back in the field and making videos again. It was a shame to lose your shop but most your work seem s to be on site anyway so no point paying for something that your never at.
Love your work and have learnt alot from your videos.
Thank you for leaving and explaing the footages , great for younger newer techs to learn from.
Great video
I learned a lot
Wish you would’ve showed taking out and putting fan clutch back in.
You took your time overall with a customers vehicle and didn’t just do some random ish. Very thorough I’m sure your clientele loves you.
Love your videos. You are truly a great mechanic and system analyzer. Your explanations of complex systems are great. Just wished you were closer to where I live.
Thanks for showing everything! I wish service information would mention bias voltage.
I normally like the video before it starts cos I know its going to be good 😊😊
Wow, pretty good. Thanks
You're lots quicker than me at getting out of those rabbit holes in good shape!
The amount of information is appreciated, even if I have no issues.
Good job. At my job when someone does a repair and the machine is still not working. I check the tech's work first. I've found a few times that they made a mistake.
love your videos i love car videos i am going to be a mechanic the more vids i watch the more i learn thanks for your time and videos :)
This is the difference between a code reader mechanic and a technician. Troubleshoot till you can verify the problem and repair.
Great video Eric!! I actually did know about bias voltage… how ever it slipped my mind about Chrysler using it🤷Great job teaching us! We are all human 👍
Kudos Eric for correctly pronouncing some ignorant technical writer's misnomer.
Nice job ! Unfortunately some scab took the truck owner for a ride. I learned a lot about the pcm voltage from you,thanks again.
Brave man following behind hacks. Hopefully people will go to you first in the future.
Long Video. BUT so much helpful info. My old 2005 Dodge 2500 had a similar problem, wasn't to replace the freaking expensive computer.

Very useful. Still learning on how to test these pulse circuits and about bias voltage, this video explained a lot
Hats off, U deserve every penny for the excellent diag.
Amazing work eric! Thats a really good point on the biased voltage & that is something that we need to keep in the back of our mind when troubleshooting. Salute to you sir!
Thats a great video Eric and explaining bias voltage and always test and not guess as seen ecu put on cars as they not checked wiring and rule out new parts already fitted that are faulty or been broken when fitted
Glad you didn't just throw PCM in it. Great job.
Good stuff dude. Love the electrical troubleshooting videos.
Your a class act man. Great work! I love the part about guys that know everything. No kidding!
Love the channel man 😎🇺🇸
Eric I really admire your ability to diagnose even though it meant 2nd guessing yourself. I'm here in Tx. as well and just recently started my mobile advanced diagnostics/module programming business.

Amazing diag.. love the thinking outside the box to make sure you were q00 percent correct!
Good lessen for all of us Eric .. Good job man.
Hi I’ve just found this channel, & I’m impressed with you contents quality so iv subscribe as I’ve enjoyed it , manny thanks 👍😀
Ps I can’t understand why a manufacturer would put a computer and all the wire plugs in scutch a place where it’s vulnerable to the outside elements being so close to the ground et cetera???
Good save on the explanation at 15:50.
When something is PWM, pwr or gnd contl. I Always look at the PWM sig First this can tell me if the controller is actually working and if there is a pwr or gnd error then the check pwr and grd wgile doing BI/D/C of the device.

And as I watch the end of the video I see my self 5 years ago Fudge yea !
Member dat day!
And put DAT on a Cracker DUDE!
Great diagnosis, wouldn’t be nice if manufacturers put out better service info.
As usual, great trouble shooting Eric. I’m surprised the PCM is bolted to the engine block. I would have thought a computer would not be so close to a big heat source. It seems modern computers aren’t as sensitive to heat as old ones.
Another super useful case study, Eric!!! Thanks for posting for us to see!!!
Nice work. I learned something from this repair.
Bro you are one of the Best Mechanics Ive ever seen on youtube. What city you from?
Eres todo un maestro Erick, mis saludos desde Petaluma California me encanta ver tus videos y gracias por cada video que ases para nosotros tus seguidores
I replaced a new head gasket arp head studs rebuilt head and I had electric fans and the truck temperature gets up up to 220 226 I’m thinking to put back the stock fan clutch I have coolant by pass every time when I’m loaded the temperature goes up I think the fans don’t work good with towing
I like to see the usages of the power prob. Great job! I wonder why they are not used more often?
Awesome diagnostic! Great job.
I would make sure an OEM clutch fan was used. Others have lots of problems.
I tried. The dealer was on backorder for the next 2 months.
Amazing diagnosis!!
Damn nice work bro really educational 👍🏼 👌
Amazing!!!! love your work and I always learn so much!!!
I got a question to ask you ? What would happen you did purchase the ECM $4000 and you installed , and didn’t work what would you do to say to the customer ? I know computer plugged in it’s no return .
Eric dam good job i bet they won't go back to that butcher shop again.thanks for the good video your friend sam
How do you decide how much to bill the customer with all of the time that it took? Thanks.👍
Grandmaster "E" in full effect !!!!!!!!!!!!!!!!!
Man what a thorough job. Where are you located? I would 100% let you work on my Dodge RV.
I would have got caught on that for sure! Great lesson on bias voltage. May have just saved some guys, like me, a little future grief👍
Shop I went to assures me that it's the pcm is bad.
The fan clutch is new and they ohmed it out and said it was good. They said that the fuse is good. The ac/ transducer was good, wiring and all pins were good and had continuity. They were certain that the computer was bad. But they said they have no way of testing till they put the computer in and if it's not the issue it's on me they can't return the computer. I was about to green light them but then I saw this video and concerned. The fan that is in there is OEM and does not have the connection as shown in this video it is hard wired on the fan side plug. Am I missing anything? It's about $3500 and about 3 weeks till they can get a computer. Any input would be great
I would always check the fan and wiring first Because like Ivan says new stands for Never Ever Works especially if you don't know what parts they used
Its hard to fix something when you rule out pasted repairs. Good job.
NAILED IT ONCE MORE...THANK U FOR SHARING.......
Just found your channel.
It's great.
Brilliant as usual Eric..Thank's dude.
