W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage.
3. Has a problem been found?






Signal Circuit Inspection

Check voltages
1. IG "OFF" and disconnect CKPS connector.
2. IG "ON".
3. Measure voltage between low signal terminal of CKPS harness connector and chassis ground.
4. Measure voltage between high signal terminal of CKPS harness connector and chassis ground.

Specification : Approx. 1.4V





5. Is the measured voltage within specification?





Check open in harness
1. IG "OFF" and disconnect CKPS connector and ECM connector.
2. Measure resistance between low signal terminal of CKPS harness connector and CKPS low signal terminal of ECM harness connector.
3. Measure resistance between high signal terminal of CKPS harness connector and CKPS high signal terminal of ECM harness connector.

Specification : Below 1 Ohm





4. Is the measured resistance within specification?
