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 ?
YES
> Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
> Go to "Signal Circuit Inspection" procedure.

Signal Circuit Inspection

Check voltage
1. IG "OFF" and disconnect CKPS connector.
2. IG "ON" and ENG "OFF"
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.
A. Specification : Approx. 1.4V




5. Is the measured voltage within specification ?
YES
1) Go to "Component Inspection" procedure.
NO
1) Go to "Check open in harness" as follows.
Check open in harness
1. IG "OFF" and disconnect CKPS connector and PCM connector.
2. Measure resistance between low signal terminal of CKPS harness connector and CKPS low signal terminal of PCM harness connector.
3. Measure resistance between high signal terminal of CKPS harness connector and CKPS high signal terminal of PCM harness connector.
A. Specification : Below 1 Ohm




4. Is the measured resistance within specification ?
YES
1) Go to "Component Inspection" procedure.
NO
1) Repair open in harness, and go to "Verification of Vehicle Repair" procedure.
