GM Crazy CAN! (No crank Equinox) - Part1
Vložit
- čas přidán 23. 10. 2020
- This 2008 Chevy Equinox has an intermittent no-crank condition, losing communication with the ECM.
Parts cannon has been fired; three ECMs have been swapped in to no avail.
Owner is giving up on it, ready to ship it to the auction block!
Let's dive in and see if we can pinpoint the problem with the high-speed network and get this car to run!

i just love this guy. the attention to details is spot on. he split part1 and part 2 videos timeline in almost 50:50 ratio. part 1 - 21:44 and part 2 - 21:57.
I was expecting to see if that NY Guy walk up and say Hey Ivan, gotcha a Chevvvrroolet huh!?
I own a 2007 Equinox V6. ( Among my 4 Nissan's. ) I had the Equinox plagued overheating last Fall.
A sweet smell of A/Freeze inside the cabin.A quick Google search reveals this as a common issue.
I bypassed the Heater Core, and it has ran and cooled all summer here in Indiana flawlessly.
It is AWD, so with Indiana Snow coming, I am walking out this afternoon to replace the Heater Core.
This must be among the Top Most Ridiculous designs- to access the core. I am doing the 2.5 hr
cut the metal tubes under the dash repair- to remove this animal! ( 12-13 HR. to replace it without
cutting the metal tubes ). Looking forward to Part 2 of this case study. PHAD Rocks !
Saw a heater core replacement recently on a Ford I think that required removing both doors to get it out. Something about a long bolt that goes in towards the center of the dash from where the front door hinges are and to get the bolt out completely the doors had to come off. I’m an ex Ford guy and now will only buy Asian cars. Have yet to see this level of insanity from them yet.
Well.....this hard...
I just sit here, eat my popcorn and watch, thats all i can help 😅
This is what I call a Young man going to the next level to extend his future in life.... And I'm retired having fun watching the younger generation of machanics keeping me updated on today's technology in automotive's field ...
I admire your patience, I would have run away screaming.
And precisely this is why Eric O. recommends to do a visual and check as many non-intrusive things as possible before touching anything. The first open, then suddenly good CAN wire should've been a red herring, as should the twitching gauges. The fault was clearly present while the EBCM was bridged. At that point, get out the scope and check that wire while wiggling it and the connectors. Check pin fitment, etc. But you'll figure it out as usual.
Red flag, not red herring. Otherwise agree
Air, fuel, and spark. Got to have all three or no go. Check first.
While doing some electrical work and hoping for a quick departure, one experienced and wiser soul remarked "There's no such thing as a 5 minute job. Ever since have been trying to prove him wrong but no joy, unfortunately. That's many, many moons ago. As soon as you mentioned "Staten Island " I knew there was a storm a brewin. Cars left idle for extended periods have strange tales to tell. Tis a brave soul, like yourself that has the courage to slay the dragon. Lookin forward to more front line action on the Chevvy saga and hope that some claymore mine doesn't explode unexpectedly, on your diagnosis trail.
Been following your videos the last few weeks and finally understand how to follow through the canbus system on my '13 Chevy Cruze. Was able to find the broken highspeed line going to the power steering. Great videos very helpful! Thank you!
Sweet.... Just got home from work, and PHAD video comes up... Thanks Ivan.... You should do a live stream sometime... That would be awesome...
Wow Ivan the EICO RESISTANCE Decade box is a blast from the past back from my electronics education. Thank You 😊
Looks like an auction car, who knows what people did before. Intermittent problems, the worst, gotta get lucky AND smart. Thanks for bringing us along!
Glad you enjoyed it 😁
I I've been watching you for months your CZcams I believe you are legend great pressure video with the main looking on 👍👍👍 Fuses missing and your the
10th person that looked at this nice work my friend 👌
I like the "Parts cannon has been fired" phrase. We use "Shotgunning" similarly, just throwing parts at the problem to try and fix it.
Thank you for the video and the 2nd part! on my case it was the electronic power steering module . i just jump cans and was able to get my 120 from ecu, plug back the middle connector and finally i got my 60 and the car start right up, now time for new steering rack
Mr Dillion taught me to look at the centre of any given unknown loom and go for a connector / unit there. Reason being you split your possibilities in half in one go.
Yup perfect strategy :)
So does Eric O......
My next step would be to tell these guys to stop buying car at the auto auctions. They end up at the auction most times for a reason.
I appreciate the walk through from diagrams from the book on them to hands on situation it truely helps understanding some more complicated side of things with newer motors
Now what could keith say hmm.. Check the communication paths for low resistance and double check the termination resistance values while flexing the connectors.
I would run away of cause lol.
Great. I felt I was watching a Hollywood movie. Camera work was amazing..
"what would be YOUR next step in the diagnosis?" gas can and match? :))))
🤣🤣🤣 feels like it sometimes
Hi IVAN,What i see here is that the last mechanic failed to flush the toilet,and just left in a hurry.Maybe he was mad because when he could not get the car running and the shop owner said to him{ok,look,you didn't fix it so I'm only going to pay half your fee}take or leave it!!!
So the guy thinks to himself,{you prick}OK I'll just remove the fuel pump fuse,these guys are so stupid they won't figure it out,they don't know wiring.or he brakes a wire that's not obvious then leaves.How else does that FUSE GO MISSING???There's a reason all those cars sit for a long time at that place,they look a little shady.In my humble opinion.ALSO the fuse was removed after previous starting attempts ,that's why when you tricked it into 60 ohms it attempted to start,there was still pressure in the full line.Boy what a hard diag,thanks for schooling us,Ivan
More problems with this vehicle than a tech should have to deal with!
Missing fuses, unplugged and PARTIALLY unplugged injectors, coils, ect. (on purpose from the sale), all common stuff at my job at a used car lot!
my pontiac g5 had same wonky gage issues like tach and fuel jumping around, and powersteering warning on, bad grounds and oxidized ecu fuse from in car fuse box. cleaned fuse block pin terminal and used new 10amp fuse fixed issues
What a weird shop. Somebody pulls the fuel pump fuse and forgets to put it back in.
Haha I've learned not to ask too many questions 😂
or was it pulled to start with by a disgruntled X, then vehicles = dead and towed ;0
It's just a bad spark plug lol. The fuse is Eric's thing ...just another great video Ivan thank you
Equinoxes have a j-connector in the floor under seat and carpet, if it gets wet or rust on prongs vehicle will not start
Oh Oh Ivan here you go again! LOL. Hope I have better luck tomorrow on the Equinox I am going to look at!.
You sure can find them Ivan.
Thank you Ivan. Good job. Have a blessed and safe week to you and your family.
I have found missing fuses before the only thing I can come up with is that they are working on another car and need a fuse so they grab one from another car on the lot /dealer in the yard where ever, probably with full internet to replace it but forget... I don’t think it is always intentional...
I have seen it with auction cars maybe they think if they pull a fuse so it won’t start they might get it cheaper but if it was a non starter in the first place .....
Me and my ex had an equinox of this body style... 07 i think.... WORST pice of junk car I ever had. Electrical issues all over!! Almost killed us.
Yikes! Yeah GM electrical components and wiring is not known to be the most reliable lol
I'm a Ford man now
I had an gm s10 4-banger truck it was a huge piece of sh. Pulled front passenger side quarter panel off to access something, come to find out gm factory pressed the body panel onto a major wiring harness from the dash with multiple wires looking like they were smashed by a sledgehammer. The lack of care of gm production of this truck is stunning.
I beet too long but I really like it thanks for your hard work.
And it's funny how they just removed fuses.
Oh man !!! I'm going to have to watch this video two or three more times ....❤
Ive ran into the same issue. One of the codes was a p0700. Noticed after doing an engine shampoo. Found the tcm had moisture intrusion into the case half’s. It gradually go better as the board dried off. But had similar issue with the cluster also transmission would not shift out of second gear. I did a resistance check on 6 and 14 but cant remember my reading. This was over 5 years agoHope this helps
Well Ivan in the beginning you asked what we would do next. Well I would close the hood and go home Lol. Ivan hope you and wife are doing well see you in part 2 😊
Well done even though it seemed like it was a fuel pump fuse, but now an EBCM!? Like the way you get things done.
Rut Row Ivan, I believe with all your knowledge in wiring you will figure this out!!
Seems like intermittent connectivity at c106. That 93k ohms may have been correct. Noticed it drifted close to 98K ohms. Would have been an opportune time to jiggle the wires and monitor the meter. I assume you then disconnected c106 to checked point to point resistance and if so, may have temporarily corrected the problem. Just a guess.
Kudos to Ivan for calling these "interesting case studies" - at our house they're usually known as inert lumps of metal on the driveway...
chaffed wires around c106? I knew when the gauges were doing that high speed was dropping out. I've seen that a few times.
With some modern vehicles the no crank problem can be caused by something as simple as a faulty coded ignition key, so the car's system can't read it so it won't unlock the immobiliser, that's what happens with bmw X3's.
Sometimes when debugging a device that won't work I check all the wiring, the components, everything. I determine that nothing is wrong with anything. So I try again and the device works perfectly. My conclusion is that the electronics were trying to play a trick on me by not working. Sometimes I can here them giggle and snigger. But after I prove everything is fine the electronics knows it can no longer play this game without me realizing they are sentient. So they allow the device to work. I am convinced that every transistor is actually an alien creature from the planet... hey! My keyboard quit working. I'll try again. From the planet... No Keyboard again! OK. I give up guys. You win.
You found an 08 equinox that still runs at all? Wow.
Yeah because it's a V6, not the weaksauce 2.4 oil burner lol
Hang in there buddy you can't keep a good man down perseverance
A no crank, start, no crank. Hmmm. Looking forward to P2. Thanks!
Intro blurb: "120 ohms"
*this is gonna be good*
Oh no you "fixed" the the broken wire while testing.
That 93kr reading was the bad wire don't worry tho we all get tricked from time to time.
very likely yes ;)
haven't watched that far into 1st video yet, I see the seconds says comeback lol
To start at the OBD2 connector under the dash.. you put the ohm meter on the can high speed and can low speed to start and if you get 120?
Amazing!! At least it runs! Lol. Can’t wait for part 2!!!!!!
I just ran into a similar issues on a 2020 Equinox. Wouldn't recognize the key fobs, wouldn't unlock or lock, alarm kept going off, wouldn't even go into accessory mode. BcM dropped LIN comm, replaced BCM, reprogrammed it and problem was solved
Would your car start before you replaced it?
Also how much did you pay to reprogram?
Someone pull the fuse to try to get a better deal for themselves at the auction maybe?
or someone pulled the fuse so methhead meg couldn't drive it and sold to shady scrapper that sent it to auction lol
Mr. Reed! Arm the Forward Parts Cannons!
Привет Иван!
Интересно, спасибо за видео!
Какое странное решение - последовательная схема CAN. Противоречит и здравому смыслу и самой сути сети CAN.
_____________________
Смотрю с интересом, Денис!
great video man ....thanks a lot for sharing ....pkease give us part two
Maybe the new ebcm needs programmed through sps? Or it’s pin figment on the connector to the ebcm
These cars that have been screwed with by multiple shops can be a nightmare, are they worth your time? Plus the shop isn't going to pay you fare? I guess you take the good with the bad with these.
I wouldn't bother with it because you the mechanic or technician deserve to get paid in full for tidying up there sloppy work
A very interesting plot. The video will pay off all the costs and time spent.
@@engeneer_ru5827 the minute I saw the missing fuse I was thinking are they trying to test iven out
Who benefits from arranging tests for Ivan? Where does the video take place, in some kind of workshop?
@@engeneer_ru5827 These are cars no one else can fix, so with Ivan's diag skills and equipment the fixes can be easy, but I bet most are not. He'll know when to walk, he's a smart guy in more ways then 1.
great job
Wish I could search comments in case it was asked already. What did the dash lights and guages do prior to the no start condition? I'm curious because I'm dealing with one now (01/05/23). Dash lights, guages, and accessories all seem to function normally. My guess is CAN communication is good. Going for the starter and stater relay (easy stuff 1st).
Did you ever figure it out?
Stay tuned for part 2 tonight or tomorrow. That car probably has some wonderful quality gas in it from sitting that long. Tune in next time for the case of who took the fuel pump fuse🤣.
The launch will cause the needle issue. I have seen it.
you moved and wiggled way too many connectors and harness, it may have been wiser to watch meter/scope (hooked at the breakout) and move around gently wiggling each plug, then harness just past each plug, one at a time! that's how I usually find broken wires in the middle of nowhere harness-land lol
Of course that Equinox is a used car. I'm thinking it's possible that the fuel pump fuse is missing because the car lot pulled it as a theft prevention measure.
Hey man I have a 2009 equinox with the exact same problem and I think I have the same problem as you, but, i'm a teenager fixing his first car And I don't have access to all the tools you have on the video. I had a multimiter and some pins as piercing probes, still this video helped me a lot, it was a shame I didn't found it before I had the complete dash dissasembled, canged BCM and ECM. And at the end i think all the car has is an intermitent bad EBCM, why, because the car would start and then all comunications will be coming and going away untill the car would just shut off in the middle of the road. But I have a question. I know it is not safe to drive with a bad ABS module, But if i bypass the comunication as you did in the video could the car drive as normal? At least untill I can afford a new ABS module.
Actually I managed to fix the comunication problem but now my transmission is overheating, Any tips? It sat for a very long time

The CAN can't do the Cancan.
Hi
Would like to see a fast dc charging system for the ev cars I know it goes through the can bus
But can’t find any information on it
It tells the dc how hard to hit the battery by raising the dc voltage
The ac charge is pretty simple it sends a 1khz tone with a duty cycle witch tells he charger how hard to charge
I want to build a dc charging system but have to figure out the canbus
Any information you can find would be helpful

Is this a customer car that was there for months or one of there own?
What is that kit you are using
Why is the shop/garage full of lots of cars for mouths on end
Because they don't have a decent diagnostic tech of their own.
I deal with some similar places.
They fix what they can by swaptronics or firing the cannon and the rest get left until they run out of room.
The cars have probably cost them well under market value so they're not fussed about them sitting for some time.
At this point they call a diagnostic tech in and maybe get a lot of them diagnosed in one go.
I've got non-runners sorted that have sat for 15-18 months at some places!
@@simonparkinson1053 you wouldn't what your car back in a hurry you'd have to own have 2+ cars to be bringing your car to these kind of garage
@@neilmurphy845 They will most likely be auction vehicles rather than customers vehicles.
So many end up at auction because others can't fix them
@@simonparkinson1053 thank you
Oops...Got to be 110% sure before firing the parts cannon...I recently did a mistake by ordering a intake cam sensor instead of an exhaust cam sensor by getting in a hurry...
I hate to say fixing this thing may be easy $$$ for Ivan, and to keep his skills sharp, but IMO in reality this toilet should just be flushed at the scrapper.
This is exactly why I drive older junk. Easier to fix.
Nice video
What reason is there for American cars to have these gongs ?
I’m really lost in this diag video as I don’t really understand the can bus high and low system. Can you or someone help me direct on where I can get a base knowledge about can bus system? I’d appreciate it. The video that you put out is always awesome but you lost me on this loo
which launch do you like best sometimes see you with small like cell phone and sometimes like tablet. and did u upgrade memory with larger sd card. i just got the 8"
giggity....
I use both, but honestly the small one is just so convenient!
i really like my launch my snapon solus was old bought a vantage legend couple weeks ago am trying to learn scopes biggest worry is when to use attenuator and when i don't need it wish you would do a video on scope basic hookups like that
did they put the vin in the new ebcm
Uh oh 😆😆🙈🙈🙈
i also forgot to ask i know you have made trips to south have you met any utubers that do diag in the south. im in southeast alabama and have small shop and thinking about doing some utube. but mainly looking for people in the south that do what you and eric do thanks
Hmm good question. Just met some fans, but not other diagnostic techs
Nnooo dont keep me in suspense. I need to know lol.
What's a ctean on a 2017 Chevy equinox please my car was dieing at stops
A CT they calling it on my equinox 2017 it's dieing
What's a CT on 2017 equinox SUV please
I love your videos, but I hate all these annoying warning sounds the cars make when you turn the key on
Like #131
Thanks for the video!
Ditto - red flag.
❤❤❤❤❤❤
You only get a full tank of gas when the tank has to be dropped ........
Lost me on this video. Why should you have 60 ohms, how did you know that?
👍🏻👍🏻👍🏻🌷
Wow, the worst vehicle ever produced!! Wow, staten Island problem!!! Haha Wow. Unreal! I'm surprised that you're working on it and not getting mad not finding the problem!!
Wouldn't ever touch anything with the GM logo ever again massive history of electronic glitches on a large range of vehicles , spanning back 20 years and yet nothing's improved , be smart buy Asian car
This video gave me a headache. I'm sure it gave you one lol
A case study on a gm electrical problem? 🤦🤦🤦🤦 Nothing new.
Today's JOKE : The guy brings his car to a shop and tells them " I have CAN 🚐 BUS trouble " . The shop , who is not well trained says " I don't know anything about the bus to Canada . Why don't you call Greyhound !
Fire the parts cannon
Daewoo chevy... Go figure... Junk it
It's just another 'grusty mistake' that is over priced and under engineered.
Avoid all these mistakes and don't buy one!!! It's an alphabet soup of
errors; or, a P.O.S.
First
