GM Crazy CAN! (No crank Equinox) - Part 2 -COMEBACK?? 

Well ,Well Well my friend. I have to commend you for your amazing skill and experience which has helped a 65 year old retired truck driver with the same exact model equinox .I had the very same SUV with the exact same problem. And thanks to you putting that video on You-Tube .I was able to solve a problem that 3 professional auto electricians who tried before could could not fix after I spent between them more than $800.00.Plus .I bought and changed several sensors a ,starter , a used fusebox and a junk yard ECM.Nothing worked and after all that it could not start.. After my SUV sat for 3 weeks.I learnt from you Sir ,that most of the the terminals even the ones on the ECM were corroded or oxidized..I followed every thing you did ,step by step and BOOM...After 3 long frustrating weeks ,my SUV started . I owe it to you my friend. Let it be known to you and You-tube .You have helped a poor man fix a very expensive problem with a Hat pin and some electric contact spray can.THANK YOU SIR. I used the pin to clear the contact ports and checked for the drag just like you said.Cleared them and sprayed them with the contact spray.And my SUV came alive again.A world of THANKS to you Sir.

You know why those 4 are loose; somebody was there before you shoving a a test probe into the sockets.

I think somebody was doing the Hockey Pokey on those connectors.

Awesome stuff 👏 👌. Glad I didn't mention c106 on the phone 🤭😉

Piercing didn't check the pins.. lessons learned.. 👍👍

4:12 is where I normally stab my finger. I wish manufactures had listing for repair terminals. Volkswagen is one of the few that sells repair terminals with 6” of wire attached so a repair can be made. We have 3 or four terminal assortments and I save every junk yard harness just for repair terminals.

It isn't just GM terminals. I have an 03 Ford Super Duty that had the same problems with the turn signal circuit. I ran the entire wiring harness from the flasher to the multi-function switch to the brake pedal switch and all of their power and grounds. Finally got a subscription to Mitchell, so I could get wiring diagrams. Found my problem of loose terminals on the back side of the fuse box under the dash. I actually replaced the pin terminals in the connector to fix the problem. This was a great diag video Ivan. Even the pros make mistakes. lol

Ivan, you're amazing! You just cured this Chevy of a terminal illness.

You always get to “pay” for your education. One way or the other.

just noticed you have over 89K subscribers ... dont know how many you had when I joined up .. but I think less then a thousand ( right after your first video with Eric ) congratulations buddy :)

That car had you on the ropes great finish sir

Ivan, the surgeon!

That cars been played with judging from that 'aftermarket' ground strap to the alternator. lol Amazing diag Ivan. Thanks!

With intermittent loose terminals, it's a bloody nightmare, to say the very least. There was obviously some one already there, fault finding with some blunt equipment not exactly made to measure and developing new problems to add to the experience. Grand session of patient detective work to uncover that lot and nice sound from the 3.4 litre.

The Elves have been working on it at night. Just the CAN contacts were spread, they didn't do it to themselves. Cheers!

Ivan,good challenging video and diagnosis. Have to get me that AESwave connector kit. Looks like a must have. You and wife stay well and safe. 😊🇺🇸

You almost need a checklist of variables when it comes to diagnostics because in the heat of battle you can forget to check something , even when it seems to be a simple diag, those are the ones that can eat your lunch. I fortunately have the luxury to be able to walk away from them for a couple of hours or more and think about the variables, when you are at someone's house or shop time is of the essence! We all have those days. Glad you figured it out, I knew you would

Great job Ivan! Thanks for taking us along.

Somebody was poking that connector with wrong leads, only way that can happen. Nice fix Ivan. Done. Ship it.

You are getting better and better Ivan. Always appreciate your videos.

Kudos to you for admitting to and sharing your mistakes publicly, so every one can learn from it. Thank you Ivan. As usual, very nice vid.

Agree with the other guys. More likely terminal spreading than fretting. That "shop" looked like a used car lot so that car had likely been "touched" repeatedly. And you already know what you missed. That high resistance reading in part 1 that "fixed" itself, and the CAN network coming and going, both pointed to an intermittent.

Wow a comeback! But you learned something along the process!! So did i too. It's one thing after another lol. Great lesson!! :) awesome video!

Wow! Always learning from you, great job Ivan!

Nobody's 100% perfect. Great stuff as always. Thank you Ivan.

First time I've watched any of your videos. Nice troubleshooting. Good to see problems like this getting fixed. Haven't watched your videos before, I have liked & subscribed. Good work.. Thanks for the honest video.

Thank you Ivan. Good job again. Have a blessed and safe week to you and your family.

Fretting can be a recurring problem also. Working on a FCA vehicle the sensor had fretting with a 20% variation. Retensioned and deoxit worked for a week light came back on then when checked it had a 1% variation. Ultimately, I learned that the programming required a 99.8% clean signal and the addition of stabilant 22 corrected the problem. Also, each pin also has a crimp that can introduce resistance. Fretting may also mean that the terminal plating could be compromised. This is our future nightmare. FCA should never have used a high amperage 3 pin headlight connector for a sensor and programmed the computed to be so sensitive. Thanks for the videos.

Great job Ivan Nice diagnosis on GM Junk. Thanks 😊

This is what we've been waiting for.

I’ve found that on cars. I once cut out connector and twisted wires together with wire nuts on a construction site at midnight to get home. Two years later the guys truck was still like that!

IVAN you freaking genius !!!!! thats one case we all would have missed , you def made up for it!!!

I feel good every time I watch a video. He fixes everything so we don't have to worry about the customer yelling at us. Truly this is one of my favorite channels. I am so impressed at how smart he is.

Wow… the patience you show in doing all that work is inspiring. I know it is 2 years ago… but wow!❤

Great Fix Ivan,you nailed it in the end that's what matters..There is a reason we call them Craptiva "captiva" in Australia lol full of gremlins.

Holy cow Ivan! I HOPE that if I ever run into one of these situations, you already have a video on it! Awesome work, and worth every penny spent, I'm sure!

Thanks for the video and analysis of why the diagnosis was wrong the first time. You learned and I learned and that's what it's all about.

Good job Ivan...Sometimes those lack of pin friction give you those intermittent problems that are hard to track down...Very similar to another fix you did before when you mess with the connection and the car was FIXED. Tarnish, Corrosion, and lack of pin friction are head aches for a technician causing intermittents that will have you going in circles. I've been there.

Typical post-'07 GM! I probably would've given up on that one - it would've kicked my ass! Nice work, Ivan.

Great video Ivan. On to the next one.

Sir you just made my day! Long story short I worked on an 09 Equinox no crank. I went through the GM pp test and of course it resulted in the EBCM being faulty. I replaced it and the vehicle started right up. Now( weeks later) I have a super intermittent CAN BUS issue where everything goes down while the vehicles running with all the same codes you had. Sure enough same pins had that very issue. GM even put out a TSB on this terminal threading issue which I neglected during my first diag. Great video can't thank you enough for this vid!

Awesome video man. You have the best ones here on YT

Phenomenal videos! Thanks for posting!

Very interesting diag . Looks like they have a yard full of next ones.

I knew you were gonna figure it out and you did. I believe in you. Brilliant technician like you or Eric O. can make mistake or wrong call. I made few mistake but I figured it out and I fixed it. Struggle is very real 🧠. Nice lesson. You must be tired from this Chevy.

Great content Ivan

Autel Should send you their new scan tool with the j2534 pass through. I’ll d they did that... you could get in2 programming. Then you could halve flashed that module. I’d love for you to start programming. Autel should make that happen!!!

You're coming in behind another tech(s) and who knows what kinda damage they did probing terminals. Good job sticking to the end and getting it fixed!

Nice work brother. In my 10+ at Honda I can not remember 1 time I had that issue. But Honda used to have alot of bulletins on checking drag and greasing connector backs as a preventive for issues that were known.

Great video man 👍 very informative keep up the good work and thanks for sharing .

Ya, I agree with Tonyfremont. Unlike Ivan, they gave up after spreading the terminals open. Good troubleshooting Ivan! The world of small terminals and micro or nano amps got this vehicle for sure after someone else messed with them! YOU FIXED IT!

Great video Ivan ,we all learn't something from this..Thanks..

I have always said, in your car there are 2000 moving parts, working at high temp, high pressure and under great strain, any faulty one of which can disable the car. Of course there are literally thousands of electrical connections which are under no strain any one of which can disable your car also! Its amazing that any car at all actually works.

Well done with the camera work on such a fiddly job, Ivan. :-D

Thats cool Ivan thanks buddy

You are awesome 👌 beautiful diagnostic was though.

Another crazy case study for Ivan. BTW Ivan love the new snap on scope! Made the p0017 diag easy. It is out almost 8 degrees!

Thanks for sharing this experience.

One of the highest order checks in GM manuals is pin drag test, so it shouldn't come as so much of a surprise!

Tough diagnosis!

Hey, that's my kind of music there on your backgroud.........you have some Dominicans there working with you!! That's some old great original Merengue music......it's not made like that anymore.....sorry not mentioning your awesome repair there..

Good find!!

Great video 👍👍👍👍

That engine bay is really clean.

I had a similar problem on UK Vauxhall (GM) traced the CAN line fault to to an ecu with can in and can out much like yours. when back probe was used reading were good comms came back turned key and it started BUT had a scope on engine ECU and as i removed back probes and scope trace went daft and engine stopped when i de-pinned the connector it was clear it had been crimped badly . no copper was in the connector (cut to short) but the part that traps the outer insulation had just pierced the insulation and made a bad intermittent connection which had got worse over time !!! So i learned not to back probe looking for connection issues but use a piecing type connector two or three inches up the cable away from the ecu connector block i have found meany similar problems since ... hope this helps someone!!

Nice job finding the issue with this one

I learned so much this time how to evaluate resistance, how to give life to poorly made connectors, and one place to look to for a lean fuel trim. Ivan that was the fastest I have ever seen someone clean up a lean long term fuel trim. I will have to buy that aes wave connector kit. GM shame on you for making such poor connectors.

Well done ivan :-D What a pain in the ass that was :-( Those connections don't selectively go loose, some messing with the connectors must of happened sometime. I wonder what the original fault was before someone created more problems. You may never see that problem again (hopefully), as different cars have different connector styles. Fingers and toes crossed ha ha :-D

Nice diag. You really don't stand a chance without the proper terminal probe. Worked as G.m. pre service line tech, found terminal tension out of the plant was rampant. The only repair allowed was replacement with a terminated lead, no tweaking accepted. Most terminals part # were available thru service information, no way to find that # if you started in the parts catalog. Although the supplier builds millions of harnesses with terminals, you cannot make each perfect.

In general most automobile build quality isn't there no matter what brand it is anymore it is all about the numbers and mass production. it would make your head hurt if you set and think about how many hundreds of millions of vehicles could be breaking down all of a sudden and how many could lead to wreck, death or leave you stranded if they malfunctioned at the wrong second.

tedious work.... nice Job I don't have the eyes for this anymore, maybe I need a super light like yours, again we'll done

That was a PITA but nice repair Ivan!

very well done i hope you got extra money for 2nd fix

Avocados from Mexico---good.

Nice !

Elite x431 for the win Aes wave adapter kit For the assist great video 👍👍👍👍🎓

Cam bus faults , hate them . Good testing methods 👍

Loose contacts! This is probably the most difficult to troubleshoot, especially when intermittent, but freaking easy to fix when found!

Nice video

Perseverance never give up back up regroup and get her done follow your dream and don't slow down you'll do good son

Now that was a tricky one indeed. Feels as if someone had done some testing with incorrect size pins. Since only the CAN pair pins had the issue.

8:51 "infinity"... no: overrange for your particular meter. As someone who's job involves tests with Tera-ohm resistors I can assure you: there's no such thing as infinate resistance on planet Earth. As with everything in the physical world, things get unintuitive when one pushes the limits. Edit: multiple contact problems in the same wiring harness... fun.

So finally it was the EBCM conecter. And why the ABS is related to starting station? Good job thanks for your time.

Why buy 'them' fancy test probes when you can jam an ice pick in there...

Привет Иван! Браво, ты победил! На старых Toyota (правый руль), с которыми я часто имею дело, все разъемы заполнены белой смазкой. Думаю, что это технический вазелин. В Советском Союзе, эта смазка называлась ЦИАТИМ и всюду применялась. Что ты думаешь об этом методе защиты разъемов? ______________________ Смотрю с интересом, Денис!

Have you ever used stabilant 22 ? Developed by the elevator industry. Liquid that makes electrical continuity even with loose terminals.

Can't believe one got buy you, no hope for the rest of us LOL

SO did the equinox need a purge solenoid or did it remain unstuck removing lean code?

Like #70 Thanks for the video!

I work at new car factory of a german brand of car and we see same loose pin issues. Also some broken wires at the pin crimp that you find when gently pulling on insulated wire where it goes into the weatherproof seal of the connector hole.

Ivan.. how do you update your Launch..? Awesome lessons man.. 👍

amazing work as always .... also chevy garbage lol

Don't you miss the good old days of standard ignition and HEI ?

Those can terminals look like dupont jumper wire terminals. The drag on them do wear out quick.

Still a good recovery from a lot of curveballs

ممتاز. Great

Hey how do you like that launch pocket scanner?? Or have you done a review video for it?

Great job I wish I had you around to help me. I have just one question if possible. 2010 Chevy traverse lt replaced throttle body crank and cam sensors after several codes for throttle body and a ground short P0698. Fix everything car was trying to start with no codes and then the code P2176 pops up and now it’s not trying to start but does crank. Any suggestions would be greatly appreciated please and thank you 🙏🏻

Ivan's head cam seems to always be on ENHANCE.. ENHANCE.. 🙂

👍🏻👍🏻👍🏻👍🏻🌷
