Attention: TDR Forum Junkies I am getting an arc in the voltage from the PDC. I am wonder what is the voltage regulation circuity in the PCM. What tests can be done to see if it is bad???
If the P-1693 code comes up, is the companion code that should come up ( ECM/PCM ) not coming up is that the one that is bad ????
