- This vehicle was scheduled for a check engine light diagnosis. On the way to the shop, her engine stalled out and would not restart. She had her vehicle towed in, and the no start is the failure that I diagnose.

Voltage drop test is such a simple yet overlooked and/or misunderstood test.
Awesome job PJ.
I agree Chris! And I had to make the video, consider my channel name! lol
What are your thoughts on an intermittent no start with security light? Got a new key programmed and it still does it..
Happen to know if any codes are set?
@@VoltageDropDiagnostics Went to Toyota and it was setting a code in a module complaining about the column lock apparently. Turns out i just needed to clean the column lock plug pins and it starts up no issue now. Was quoted over $600 for a new lock so went the cheap route.
VDD doing VDD testing...oh, the irony! Nicely done sir. Wonder how many guys would have tossed a starter in there first lol
Joe, if you only knew the backstory to this vehicle that I left out of the video... lol
I have a cable with a ring terminal on one end and a battery clamp just for these situations. Great video PJ
haha! That's a great idea!
I appreciate your walkthrough of the engine-to-ground voltage drop test. Great video, as you always do!
Thanks, Dave!
a new Transmission in a Toyota? Scotty's says it cant be.
I know! Honestly, I was surprised. I’d like to know the backstory to why the trans was replaced.
@@VoltageDropDiagnostics Maybe it was a JSD fail? We've had a few. Any idea if it was done at a dealer?
Toyota Ron no. It came from an independent shop.
Hello Mr. how are you and your health it goes all my sincere greeting, I'm a young Haitian, student in 3rd year Auto Mechanical in Haiti , I am so passionate about mechanics but in Haiti we lack the practice in training centers and I am interested in venturing myself in one of the garages in USA, hoping that my request will receive a favorable opinion, I beg you to agree, Monsieur the expression of my distinguished feelings. Thank you for your available
That shows just how important volt drop testing can be! Thanks for the great video.
Thanks, Frank! It is my favorite test to perform.
Haha, yea I bet it is by the name!
I'm here, appreciating the video and learning. Thank you for sharing some knowledge!
Thanks for the knowledge you have provided, but please what voltage should i expect from engine to battery ground
Awesome, I had to giggle when the jumper came out to provide a good ground, I do that lots. Nice Job!
haha! It's the best tool for the job, though, right? haha
Why is my 2014 corolla not beeping when I turn the key to II?
Sir can you please explain,,why my Toyota Corolla 2015 engine are not starting in winter morning (5am-9am)
Sir can you please explain,,why my Toyota Corolla 2015 engine are not starting in winter morning (5am-9am)
It’s 3am and I’m watching the video.... love it ! 🤙
Thanks Carlos! You're the best!
Well done. You are a great source of knowledge. ✌🏾🙏🏾
Thanks you!
Great video PJ! Thanks for sharing! I wonder what would cause the fans to run on high.
If I’m not mistaken I think Nissans would do that when it’s a no comm with the PCM. I could be wrong.
I think you may be right. The ECM grounds to the engine, and obviously the engine grounds to the battery. So I am on the same page with you, thinking that the ECM had no communication because of the bad ground.
Nice diagnosis. Thanks for going back and checking the voltage drop again at the end.
No problem! Thanks for watching!
A 2014 Corolla that had a bad transmission? I guess Toyota isn't making them as good as they used to
Honestly, I rarely see transmissions fail on Toyota’s. I’m not sure of the backstory on this one as to why it needed a trans.
@@VoltageDropDiagnostics so transmission was bad or just dirty?
Nicely done pj! Love the lighting 👍
I'm trying to improve the videos! LOL
Wrong application for what I need soooo
Nice! Thanks for watching!
You put your key in, you HAVE something but you dont have crank. I wish the title was a bit more explicit, no start, no crank after transmission replacement, radiator fan on with key on and as I did notice, some of this was on your thumbnail. Thanks so much for the Voltage Drop test after all, that is why you are here but why did the radiator fan run key on engine off in this case? What is the Toyota strategy behind that?
I think the radiator was coming out because the ECM grounds to the engine. And without a good engine ground the ECM was probably losing communication causing the fans to come on as a fail safe.
Always interesting, informative, and educational. Thank you for sharing.
Thanks for the support Andrew! I appreciate it!
Boom! Just like that, magic.
Thanks Wyatt!
I’ve never performed an engine to battery ground voltage drop. Very cool. That was a super quick diagnostic.
I voltage drop most grounds anymore. Its my go to method for checking grounds.
Oh yeah I almost exclusively voltage drop everything anymore it’s so much better than continuity
Great example of why Voltage drop testing is so important.
I agree, Kirk! Thanks for watching!
Hey can you name all the scenarios in which the rad fans default? I thought it was a bad temp sensor or related... I usually put my test light on the signal wire of the starter. If it's lit I need a starter. I didn't quite get your way of testing it. Maybe I need to watch it again
I "THINK" that the fans were kicking on because of a communication issue with the ecm. The ecm grounds to the engine, and obviously the engine wasn't ground back to the battery so I think the fans were kicking on because of a loss of communication with the ecm.
who to ask other than a seasoned Toyota tech....2000 Toyota Avalon 3.0l pcm replacement due to a p0773...what are my options, i'v had this vehicle on j2534 techstream in an attempt to reprogram a used pcm and i don't remember seeing immob functions or vin writing ...i have a few scanners with immob functions, 906bt, torque, im508...shop tried getting a vin'ed pcm and immob set to automatic registration mode but the im508 shows 3 keys.....what to do
billmck12345 the only way to use a used pcm on those is if you either eeprom the immobilizer function completely out of the pcm, or if you put it back into automatic registration mode.
If it’s showing that 3 keys are already programmed, it doesn’t sound like the eeprom took.
Did you do the eeprom work? Or did you have someone else do it?
they got it somewhere online....what about getting a blank pcm
so buying a techstream sub to try to get through the immob is out of the question....note. im not very familiar with techstream as i'v only used a few times
billmck12345 techstream won’t help you out on this one. You can either do the eeprom yourself. There are videos on TH-cam on how to do it. Or send it out. I have a friend that does it, if you want his contact info.
do you have contact info
TH-cam rookie 😂😂😂
Great job as always bro!
haha! Thank you, Alex!
great diag VDD thanks
Thank you for watching!
barely over 100k and has a new trans? I heard of another failing at around 80k miles.. Such junk (And I have one, at 54k miles) Mine acts like it wants to stall when at idle in drive.. RPM's hit 500 and shakes bad, toyota says its completely normal.
Dpa SFT I’ll be honest with you. I haven’t seen many corollas transmissions failing.
And as far as your car idling low, has your battery went dead, or have you had the battery replaced recently?
@@VoltageDropDiagnostics yeah, when they sold us the car they did a warranty repair on it because the battery had a bad cell.. this was before we got it, turns out the battery was 72 months old and was weak, never failed to start the car but we replaced it to be safe as the testers said it was only doing 260 cca.. and were driving up to Minnesota in 2 weeks.
Replaced the battery but it's still doing it, the rough idle goes away if I disengage the trans by putting it in neutral or park
Oh and the dealership refused to warranty the battery because I didnt buy it.. but it was done in the used vehicle certification process or whatever
Dpa SFT how recently did all of this happen? As far as the battery replacement.
@@VoltageDropDiagnostics the battery was replaced on Nov 15th idle issue has been an issue since we got the car about 1.5 years ago but they blamed a throttle body being dirty, cleaned it but no change. It's been ignorable for a while but got noticeably worse this last month or two where its nearly every stop
Dpa SFT yeah, 9 times out of 10 it is because of a dirty throttle body.
It’s easy enough to do yourself if you don’t trust that they did it.
Otherwise, I advise you taking it to another technician, one who specializes in diagnosing vehicles.
Hi guys, I had a short yesterday while wiring up some fog lights and now the car cranks strong but isnt starting. When I turn the car on/acc mode I do not hear any fuel pump noise so I am thinking its a relay.
Initially, ODB fuse and radio fuse were burnt but replaced but still no start.
I just can't seem to find where the proper relays are for the fuel tank and/or EFI relay to try and replace or test it.
I checked the owners manual but no mention of these relays and online I seem to find different answers on where these relays are located : I did test every fuse and relay I could find/access and ALL OF THEM tested fine. I am lost at this point and wondering if it’s Ecu?
What kind of car, and what year?
Gotta love those rattle can remans! Nice find!
Yup! I'm surprised that this thing has already had a transmission installed in it. It actually had low mileage.
That thing sounds like it needs an oil change!
You are awesome man. , can you explain me the voltage drop test . The positive led ( goes to the engine ) at any place ( I suppose any ground location right ). And the ground led to the ground terminal at the battery ?? Thanks in advance.
Rodrigo Moran you got it. This is how I check a large majority of my ground wires.
So if I am checking a headlight circuit, and I have the headlights turned on. I check for 12v on the power wire.
Then I move the positive lead to my ground wire, and check for voltage on my ground wire.
If i have about 250-500mv (depending on how large the load is on the circuit) i know that I have a ground problem.
Doing a continuity test for ground wires isn’t good. A single strand of wire in a harness will show good continuity, but won’t be able to carry the amperage needed for the circuit.
I hope that helped!
Thanks 👍. Got it.
In Bill N Ted's voice.
Excellentttt..
Such a simple test, very often overlook..
Great way to show in action..
Gracias Amigo😁
Thank you! It’s my favorite test, for sure 😆
👍👍
Thanks for the video!
Thanks for watching! For some reason, you comment ended up in my spam file! Such a spammer, you are, saying "Thanks for the video" :)
A lot of lads could let off the parts canon. Nice and short but to the point, thanks VDD👍
All four windows don't work
Great video,why was the fans kicking on with the bad ground?then they weren't when the ground was restored?
I believe that the fans were kicking on because of a loss of communication with the ecm. The ecm grounds to the engine on this engine. I believe it is a fail safe, but don't quote me on that.
You do like voltage drop don't you 😁 Great job PJ. A lot of techs would misdiagnose this. Thanks for sharing 👍
I do! Lol. It’s the first test that separates the men, from the boys 😂🤣
That was very cool. Must have come in early to film. I guess that was voltage drop diagnostics in action. I like that record feature on your vom
Yeah, I usually sneak in around 5 in the morning to film, or I stay a little late, after work. My shop is too busy to film during the day usually.
Does this model have an inertia fuel cut off switch?
No, no inertia switch on toyotas
Good job. Make very simple to understand. 🇨🇦
Thank you!
What's the story with the fans you mentioned several times?
Well, right off the bad, it’s unusual that a fan kicks on when you have a bad starter. So i knew that it most likely wasn’t a starter issue.
But I’m relatively confident that the fans are kicking on because the ecm is losing communication.
The ecm is losing communication because it grounds to the engine that has a bad ground.
Thank you Patrick. Good job. Have a blessed and safe week.
Thanks, Billy!
Couldn't suit your channel name any better
haha! I HAD to make the video! I was 20 plus videos into my "youtube career" and had a channel name for an electrical test that I never got to perform on video! haha
Just tried the negative terminal to the engine and no go on my 92 SC300. No fans come on and no CEL either. Received the car this way.
Perfect example of a VD test. Thanks PJ.
I had to! I have over 20 videos now, and I didn't have any voltage drop test videos...yet my channel name is voltage drop diagnostics! haha
I have the same problem. Once I hook jumper cables to my Corolla it will start! Drive it for about 20 minutes turn the car off nothing!
It will crank and start once I put jumper cables to it again. Could that be a bad starter or ground cable?
I am going to take the battery this evening to have it tested at AutoZone
thank you
Awesome
Hey PJ! I have an 03 corolla with 285k kms on it here in Canada and I have the issue with the fan turning ON immediately right before starting the engine. It does when the engine gets warmed up but the fan turns ON and OFF as it should. I'm not sure if this is normal and I have checked this with the local mechanic and they said it is normal Cheers!
Bad ground
Really informative video. I bought a 2010 Corolla with intermittent no start/crank issue. Tech thought it needed a new starter and replaced it, but few days after I noticed it still does same thing. Any suggestions? Battery and alternator are good.
So what did you have to do to fix it?
Cleaned a ground from the engine/trans to the battery.
Short and to the point. Nice video.
Thanks, Josh!
Very educated man thanks
Thanks for watching!
Nice job troubleshooting, well done!
Great video 👍
Thanks 👍
🚙💙
Great stuff thanks
Thanks! I am glad you liked it!
GOOD VIDEO
Thanks!
Awesome work Pj. I make it a habit now to do ground to ground voltage drop on no starts after I almost got burned on this 07 jeep wrangler. Thank u for the reminder Pj 😁. Would have loved to see how u knew that was the bad ground and not another ground point ☹☹. I will check in wiring diagram. Take care PJ
Easily! That is the only ground wire on the engine/transmission haha! It was either where the ground connects to the transmission, or where the cable runs from the transmission to the body of the vehicle.
TH-cam rookie 😂😂😂👍
Great video and very informative as always...I enjoy everything you put together man...always learning from great minds like yours!
The jumper cable trick though 💯❤👍👍👍
Keep up the great work and again my apologies for not being on top of your content as of late!
No worries man! Its hard to keep up, and we are all busy!
Great knowledge
Junk CVT
😂🤣 i was waiting for someone to say it! Haha
@@VoltageDropDiagnostics LOL I couldn't help myself. I have a 2005 Corolla with 200k with the OLD 4 speed auto. Shifts perfect. Drain and fill every 30k.
Good call PJ. Voltage drop testing is key to testing a no crank. 👍🏻👍🏻
Thanks! Hey, I am editing my diag cart video, can I add your video of your diag cart to my description, as an example of a boom that I may try to build?
@@VoltageDropDiagnostics Go for it man. Don't mind at all
😎👍
Thanks for watching!
👍👍
Why does a 2014 corolla with 108k miles have a new transmission? Why? There is no reason why that should have a new transmission, none. Someone explain to me why a reliable, fairly new and fairly low mileage, toyota has a new transmission.
NICE1!!!!
Thank you!
