Re: Failed Mass auto inspection
I'm not sure what a used PCM will set you back. If the cost is significant,
you may want to ensure that all the wires to the DLC have continuity to
wherever they go. It may sound like a daunting task but, IIRC, less than
half the pins on the 16 pin DLC are actually used and even less than that
are required for PCM network communication.
You can start by looking for pushed out pins in any connectors.
I'm off to school tomorrow night for three days so it will be difficult for
me to find time to write up a pin out (and my job prohibits me from doing a
cut and paste on shop manual content)... this may be a time where an AllData
subscription might help you.
As an afterthought.... Blue Streak (Standard Motor Products) used to offer a
reconditioning service. I'm not sure if they still do but it's worth a look.
I only tried them once and was disappointed but that may be the result of
the nature of the concern I was addressing.
