Power Circuit Inspection

WARNING: This page is about a different variant/trim than selected.

■ Open Circuit Inspection 

  1. Ignition "OFF".
  2. Disconnect "ATM solenoid valve" connector and PCM/TCM connector.
  3. Measure resistance between power of ATM solenoid valve connector and power of PCM TCM connector.

    Specification:  Approx. 0 Ω

  4. Is the measured resistance within specifications?

    YES 

    • Go to "Circuit short Inspection" procedure below.

    NO 

■ Short Circuit Inspection 

  1. Ignition "OFF".
  2. Disconnect "ATM solenoid valve connector and PCM/TCM connector.
  3. Measure a resistance between power of ATM solenoid valve connector and chassis ground.

    Specification:  Infinite

  4. Is the measured resistance within specifications?

    YES 

    • Substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

    NO
