W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminal condition. 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" and disconnect APS connector.
2. IG "ON" & ENG "OFF"
3. Measure voltage between harness terminal 4 of APS and chassis ground.
A. Specification : Approx. 5V




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

Signal Circuit Inspection

1. Check short to ground in harness
(1) IG "OFF".
(2) Disconnect APS & PCM connector.
(3) Measure resistance between terminal 2 of APS harness connector and chassis ground.
(4) Measure resistance between terminal 2 and 5 of APS harness connector.
(5) Measure resistance between terminal 2 and 6 of APS harness connector.
A. Specification : Infinite Ohms








(6) Is the measured resistance within specification ?
YES
- Go to "Check open in harness" as follows.
NO
- Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedure.
2. Check open in harness
(1) IG "OFF"
(2) Disconnect "APS" and "PCM" connector.
(3) Measure resistance between terminal 2 of APS harness connector and terminal 54 of PCM harness connector.
A. Specification : Approx. below 1 Ohm




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