Is resistance within the specification?
YES
- Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Check PCM for contamination, deterioration, or damage. Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
