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. Check voltage
(1) IG "OFF".
(2) Disconnect the main relay.
(3) IG "ON" and ENG "OFF"
(4) Measure the voltage between terminal 30 of main relay harness connector and chassis ground.
(5) Measure the voltage between terminal 85 of main relay harness connector and chassis ground.
A. Specification : B+




(6) Is the measured voltage within specification ?
YES
- Go to "Check short in harness" procedure.
NO
- Repair Short in power harness and go to "Verification of Vehicle Repair" procedure.
2. Check short in harness
(1) IG "ON".
(2) Measure the voltage between terminal 38, 39, 40 of PCM harness terminal and chassis ground.
A. Specification : B+




(3) Is the measured voltage within specification ?
YES
- Go to "System inspection" procedure.
NO
- Repair short in power harness and go to "Verification of Vehicle Repair" procedure.
