■ Check for Open in Harness 

  1. Ignition "OFF"
  2. Disconnect PCM and IDB main harness connector.
  3. Measure resistance between Pin No. 9 (CCP-CAN-HIGH) terminal of VMCU harness connector and Pin No. 27 (CCP-CAN-HIGH) terminal of IDB harness connector.
  4. Measure resistance between Pin No. 34 (CCP-CAN-LOW) terminal of VMCU harness connector and Pin No. 26 (CCP-CAN-LOW) terminal of IDB harness connector.

    Specification:  Approx. 1Ω

  5. Is the measured resistance within specification?

    YES 

    • Fault is intermittent caused by poor contact in the sensor's and/or PCM's connector or was repaired and PCM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
