How did the u0100 lose communication with the PCM?
U0100 Lost Communication with Powertrain Control Module (PCM) – Bus messages not received from the Powertrain Control Module (PCM) for approximately two five seconds. With the ignition on. Battery voltage between 10 and 16 Volts. Ignition Off Draw (IOD) fused installed.
What to do if your PCM is not working?
Now these 2 problems combined would lead to think that there is some electrical connection problem with the PCM.
