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?






Ground Circuit Inspection

Check for Open in Ground Circuit
1. IG KEY 'OFF'.
2. Disconnect FTPS harness connector and PCM harness connector.
3. Measure resistance between both ends of ground line.

Specification : Below 1 Ohm


4. Is resistance within specification?






Signal Circuit Inspection

Check for Open 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?





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

Specification : Approx. 0V


5. Is voltage within specification?
