W/Harness Inspection

Terminal and Connector inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) 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?






Power Circuit Inspection

1. IG KEY 'OFF'.
2. Disconnect FTPS harness connector.
3. IG KEY 'ON'.
4. Measure voltage between power terminal of FTPS harness connector and chassis ground.

Specification : Approx. 5V


5. Is voltage within specification?






Signal Circuit Inspection

Check for Short to Ground in Signal Circuit
1. IG KEY 'OFF'.
2. Disconnect FTPS harness connector.
3. IG KEY 'ON'.
4. Measure voltage between signal terminal of FTPS harness connector and chassis ground.

Specification : Approx. 5V


5. Is voltage within specification?
