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.

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.

These ECMs are not repairable without special equipment. In was hoping they would approve getting a module so I could show the internals and why they are so unreliable but they decided to scrap the car. This ecm is used in a lot of vehicles, even Ferrari used 2 of them in one of their cars(v12 engine I believe) and they suffer failure all the time as well. It was a terrible design internally.

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.

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.

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?
