Just your typical Cady CTS No Start 

This is where experience pays off. Thanks for bringing us along on this one. I look forward to your videos!

From a ECM standpoint the class 2 bus circuitry is very simplistic as compared to an HSCAN interface IC, and probably uses part of an off-the-shelf logic chip or transistor (for example a CMOS hex Schmitt inverter) in the circuitry. If so, the logic IC can be taken out by static electricity if one of the ceramic SMT input ESD caps are cracked (failed) which is not uncommon depending on where they are on the PCB in relation to the connector, and if subjected to any mechanical flexing, or perhaps the ECM is loose and can vibrate the connectors and the harness. This is an excellent opportunity to see if we can repair the ECM.

Your videos all have very useful, high quality graphics and editing. I wish you many more subscribers!

Great tip on the data references, never new that! Thank you!

Thanks for this video. I found myself chuckling along with you. Kind of made my day a bit more fun. Thanks for Sharing!

Thank you for another great video and walking those of us who don't have your experience through the diagnostic process in order for us to make the right diagnosis. Nobody explains your thought process better than you do. Thanks again.

And that was toooo easy, lol. Loved the way you did this diagnostics, so well explained and slow, not rushing anything. 👍

Thank you Jake. Good job. Have a great week.

Thanks for sharing. Have a good one Artie 👍

Awesome info! Thanks for sharing 👍

Nit pick. If the buss is fast enough, you can run into problems if the termination is missing. The reflections off the unterminated end can corrupt the data. This can lead to odd things like A can talk to B and C, but B and C can't talk to each other. It's all about where they are along the buss and how the reflections hit them.

Those Bosch Motronics are terrible ECMs not only on GMs, also on VWs, Volvos and Mercedes-Benzs. The first cars that have the GM High Feature V6 uses only those Motronics before GM swapping them for Delphi or Delco; I think heat is going to be the most common issue, as well as Vibrations because they are mounted in the upper portion of the engine.

Sound thought process! Of course, your experience with these faults, makes the diagnostic faster :-) Wonder if those ECMs are repairable, all having a similar fault.

Thank you sir

Nice ❤ is there any bonus footage for this one ??

Grasias

👍👍👍

tks

😊👍👍

is that the new im608 pro 2 ?

I noticed the ground for your data signal wasn't quite zero, it was ~0.5V, but with key off the baseline was clearly zero at 7:27. Is that non zero ground a result of the internal defect within the PCM? Or, is that level of subtle difference often seen and not relevant?

Do you have any luck with rebuilt ECMs? It seems to be hit and miss.

I was hoping you were going to pull it apart.

I get new ones from the dealer and they still fail

It took me watching several of you vids before I subscribed and added you to the all star list of Ivan PHD , Eric O SMA , Eric Advanced level auto , Super Mario diagnostics and last but not least Keith DeFazio I'm 70 years old and suck this stuff in like a sponge 🧽 Everyone in my extended family calls me first before shooting the part's Cannons I appreciate sharing your knowledge thank you very much

Thanks for sharing Jake.

Thanks for sharing your knowledge with us My Mentor Automotive Diagnostics Programming SUBSTANTIAL Automotive Diagnostics Programming From Nick Ayivor from London England UK 🇬🇧 ⏰️ 15:17 good Afternoon

That has to be one of the worst cars ever made.
