C5 Vette Dissassembly?

[lionelhutz]

OK, the PCM monitors the F and L signals. I want to know exactly what the PCM is doing.

The service manual does not contain the information I'm looking for because it doesn't describe the PCM fault detection logic (you know, the exact tests, levels, timing etc in use - or a flow diagram for the piece of code that detects faults).

I can troubleshoot connection issues and failed alternators just fine. I can't troubleshoot this fault message that appears only on engine-start without knowing what the PCM is doing.
