W/Harness Inspection

Terminal and 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. Connect "A/T SOLENOID VALVE" connector and install device for measuring waveform.
2. Turn on the Engine and operate Damper clutch.
3. Measure waveform between TCC solenoid valve terminal of the sensor harness connector and chassis ground.









4. Is voltage within specifications?






Signal Circuit Inspection

Check Signal Circuit Open Inspection
1. Ignition "OFF".
2. Disconnect "A/T SOLENOID VALVE" connector and "PCM/TCM" connector.
3. Measure resistance between TCC solenoid valve terminal of the ATM SOLENOID VALVE harness connector and TCC solenoid valve" terminal of the PCM/TCM harness connector.

Specification : Approx. 0 Ohm









4. Is resistance within specifications?





Check Signal Circuit Short Inspection
1. Ignition "OFF"".
2. Disconnect "A/T SOLENOID VALVE" connector and "PCM/TCM" connector
3. Measure resistance between TCC solenoid valve terminal of the ATM SOLENOID VALVE harness and chassis ground.

Specification : Infinite









4. Is resistance within specifications?
