[@billyyoder8171]

Keith, I know you know this. You are so appreciated. Really enjoy watching your videos. Better than anything on cable tv. Bless you and your family. Have a good night.

[@kimbowles8553]

Sir, our 2015 is at the dealer currently with the exact symptoms as in the video. The dealer has called me twice today, and asked what I saw and did...Service writer stated they dont have communication with the ECU and are calling GM for advice...Tire air system low light indicator on, Air bag Service light on, key fog doesnt work, dash lights out, no volts shown on the gauge, when turning the key to on/start... Thank you for being a true professional in the industry!!

[@EXOVCDS]

Huge pleasure to watch you work!

Outstanding vid Keith - love watching the comm issue diagnosing.

[@phprofYT]

Oh, dang. A Chevy Traverse. Dump that crap fast. My brother-in-law has a friend that use to work on those all day long at a Chevy dealer. He was low man for 2-3 years and so they stuck him with all the "fun" jobs. He can't even remember how many transmissions on less than 3 year old Traverses he replaced. He quit that job and is now working for a heavy equipment place and is much happier. He's dang good at Cummins engine work as well.

[@michaelsanchez4202]

Just ran into this today I was dumb founded and was about to send it to the dealership. I used this as a reference point following your step with a multimeter and found the climate control also was the issue. No start,no communication,no radio,no hvac,no gauges working intermittently, and inop key fob. Thanks for the info sure was a lot of help.

[@NewLevelAuto]

Glad I was able to help!

[@SmittySmithsonite]

Real fine system automakers have created. And everyone wonders why I love cars built before 1996 ... This was GREAT, Keith! Learned alot on this one. It really isn't as complicated as my mind makes it out to be, once you isolate and test each leg like you did. Of course, the right tools make all the difference too - I'm still working on that part of it. 😊 LOVED the vid - THANK YOU!👍

[@NewLevelAuto]

Smitty Smithsonite awesome, glad you liked it !

[@mechanic_marky]

I love videos like this. You are excellent at what you do. A friend of mine called me on an 08 Acadia that I cant communicate with the engine ecm or hatch module. Has loss of communication codes stored. I bought a pico scope and want to use it. You have had multiple videos using that GM low CAN plug with the jumper connector. I think that is super useful to know to "separate" the circuits and narrow down a problem. I understand why your stuff is quick and to the point but man it would be awesome to learn it all. Then again i know experience is key. I work on heavy construction equipment and not automotive so seeing you and select others on KZbin helps a lot.

Holy hell. If I hadn't seen it I probably wouldn't have believed it. No start due to climate control module. Unreal. Awesome diag Keith. Thanks!

Never disappoints, i wish every car had splice packs. Great share Keith. But u lost the race 🏁🤣

[@goodautodiagnosticsllc7475]

Good video Keith! The OTC BOB works great with the flashing LED's. Makes it easier to see if you have com on a network. Splice packs cut diag time down as well.Especially when they are at an easy access point.

Thank God they at least give you an accessible splice pack :) Imagine telling the customer "your HVAC module was causing a no-start"...wow. Beautiful diagnosis Keith!

[@chadharmon5716]

Pine Hollow Auto Diagnostics hey Ivan

[@joneskey3950]

This makes it clear why Honda/Acura for example use a F-CAN network for their powertrain, drivetrain, brake/abs modules for fast bus-data and a separate B-CAN network for the rest of the body related modules; hvac, audio, door locks, windows, seats etc. Wait why am I comparing GM to Honda

[@pontiacsrule8761]

That's the problem with today's cars. I know they are trying to save wires. But a HVAC module shouldn't stop the car from starting. Didn't think the low speed LAN would keep the car from starting, only the high speed. Thanks for making this informative video.

[@Papadooskiss]

Very nice diagnosis sir. Show us more of this please.

[@AutoFocus-se]

Good work, I got a cheap DLC-BOB on the way, i will find out how well it works 😂 cheers.

[@DylanRabier]

Just watched this video again Keith like you told me. One question though why is there no activity on pin 2 that goes to the other splice pack. With all the modules that are on it I wouldn't expect a zero flatline.

[@daveyio87]

i had one of these last spring that was the issue, ended up finding that the terminal next to the data line is either power or ground and had bad contact melting the connector causing the fault. had to get a new module then build a new connector since a pig tail isn't available

[@3babyghost]

Great video sir, I'm working on a 2014 gmc traverse. No start only module not communicating is the immobilizer control module. I picked up a used one plugged it in and still nothing. Took it to the bench and desoldered the eeprom 95040 and transferred to donor. Still no comms. I have comms with everything else in the vehicle.

[@3babyghost]

Checked power at the plus for the immo module and have power sporadic 1.5v. Cannot find a wiring diagram for this module

[@hjs3rd]

I see you switched CAN breakout boxes from the AES LineSPI (SMART BOB) to the OTC (3415) CAN Test Box ... reason why?

Dang...Good one to know about.!! Thanks Keith. 😉😀

[@dylankinch2735]

Thats was an awesome video keith. My question to u is. I have a shop behind my house with 3 bays just 1 lift right now and im doing quite a bit of automotive stuff on the side of my full time job. I have been using all data diy up to this point when i need diagrams but i would love to get your view on info platforms. If u had to have 1 in my type of situation where diag is obviosly a part of what i do but also lots of repairs. Rusty ones cause up in northern ny utica area. Lol. Just wanted your valued opinion on what would be the best for my money

[@kieramosley2540]

im having this issue with traverse. how much does this usually cost to fix

[@freedom9783]

hey im trying to diagnosse a u0073 on a 07 equinox i have communication with the low speed modules nothing on the high speed side ive checked resistance in 6 and 14 getting a 5.27 mega ohms no crank no start trying to figure out how to gain communication again any help you be greatly appreciated its been driving me nuts! thank you so much !

[@mbarry9737]

How does the scan tool communicate with the radio, for example, when you have the junction connector jumper removed? Doesn't that isolate all the modules?

[@pricemanj]

Can you test for this with just a volt meter? My car shut off while driving after the dash light up and radio shut off.

[@nkonyanechristopher]

you've got yourself a new subscriber...

[@Schnippen_Schnappen1]

Do you know where is the other bus bar located?

[@RobertHancock1]

If manufacturers would stop making modules that would crap out and take down the whole data bus, that would be great..

[@guayaco-dm3vu]

Hey Keith do you have the other style breakout box ? Gateway I believe..

[@Diagnosedan]

I've got the same break out box but there is another brand on it. Nice wiring diagrams any good for Euros? Great work Keith i Really enjoyed this one!

[@MILO20121]

Thx u don't stop making these videos

[@arcadeuk]

The stuck-in-the-past people will complain about how it's possible for the HVAC to cause a no-start, when their Ford Model-T didn't have this problem, it does however make perfect sense from a technical standpoint in relation to how things are necessarily networked on modern cars. What does not make sense however, is why a bad module is able to short the network data line to supply voltage. Any reasonable network transceiver should be designed to fail open circuit, and should have opto, or even better magnetic isolation. The fact this module can fail short circuit on the data bus is just pure crappy/lazy/cost saving, poor engineering, in this case you can't help buy hate GM for being deliberately irresponsible, when an extra 10cents spent could avoid this situation entirely.

[@DylanRabier]

Why does it read 0 volts when jumping pin 2 Keith.

[@jeffreyherbert91]

Hi keith...have watched twice but am struggling to grasp the reason why connecting the scope to the various pins caused communication to start or stop....i know i am probably being a bit thick but could you help me out understanding the placement of the scope probes and what they show/ caused to change ....thanks Update.........watched third time and all became clear.....i was indeed being a bit of a thicky....thanks again

[@NewLevelAuto]

jeffrey herbert ahhh ok. I wasn't moving the scope around. It stayed on same pin at dlc. The pins I was moving were just jumpers to put the LAN terminals together in the splice pack
