Trying to read sensor data from 2000 c3500 5.7.
Diagnostic port has power and can read codes only from an AutoZone reader. Service manual says test for continuity for purple wire going to pcm from obd2 port.
And says to replace the entire pom if there is continuity, confirming that there are no wiring issues. Is there any chance of repairing it or should I just get a pre flashed unit from flagship one?
