Question about Cars & Trucks
Yes -- but to find that out you have to run the fault codes
Unless you have had a serious fault (battery connected wrong-power surge ),the ECM is the last item to check
battery was flat or replaced the normally resetting the ECM and CPU programs with a scanner will fix ECM problems.

Testimonial: "my volvo "check engine light"problem solved after replacing MAF sensor. thanx to FixYa!!!!!!!!! "
It means either, what it means is this, the Transmission Control module (TCM) has requested the Powertrain control module (PCM) to turn on the check engine light because the TCM has detected a ****** fualt is present, this can be any of a bout 20 problems, that is all it means. What must be done now is to have the TCM scanned for the fault code(s) that alerted the PCM to turn on the CEL.
