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 "Power Circuit Inspection" procedure.

Power Supply Circuit Inspection

1. IG "OFF"
2. Disconnect APS connector.
3. IG "ON" & ENG "OFF".
4. Measure voltage between terminal 3 of APS harness connector and chassis ground.
5. Measure voltage between terminal 6 of APS harness connector and chassis ground.
A. Specification : Approx. 5V




6. Is the measured voltage within specification?
YES
- Go to "Signal Circuit Inspection" procedure.
NO
- Repair or replace as necessary and then, go to "Signal Circuit Inspection" procedure.

Signal Circuit Inspection

1. IG "OFF".
2. Disconnect APS and PCM connector.
3. Measure resistance between terminal 1 and 2 of APS harness connector.
A. Specification : Infinite




4. Is the measured resistance within specification?
YES
- Go to "Component Inspection" procedure.
NO
- Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedure.
