W/Harness Inspection

Automatic Transaxle(DCT)
P1786 Inhibitor Switch Circuit High - Inspection/Repair:_:W/Harness Inspection

Terminal & 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?






Power Circuit Inspection

1. Disconnect "INHIBITOR SWITCH" connector.
2. Ignition "ON" & Engine "OFF".
3. Disconnect "INHIBITOR SWITCH" connector.
4. Measure voltage between "Power supply" teminal of the sensor harness connector and chassis ground.

Specification :approx. 12V

5. Is voltage within specifications?






Signal Circuit Inspection

1. Ignition "OFF".
2. Disconnect "INHIBITOR SWITCH" and "TCM" connector.
3. Measure resistance between each teminal of the sensor harness connector and TCM harness connector as below.

Specification :approx. 0 Ohms

4. Is resistance within specifications?
