Component Inspection

  1. Turn "OFF" the ignition switch.
  2. Measure resistance between High signal terminal and Low signal terminal of ECM connector (ECM side).

    Specification  : Approx. 110~130Ω

  3. Is the measured resistance within specification?

    YES 

    • Check for poor connection between ECM 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 ECM for contamination, deterioration, or damage. Substitute with a known-good ECM and check for proper operation. If the problem is corrected, replace ECM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
