W/Harness Inspection

P0773 Shift Control Solenoid Valve \'E\' Electrical (Low Coast Brake Solenoid)

Inspection/Repair - 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. Ignition "OFF".
2. Disconnect "A/T SOLENOID VALVE" connector and "PCM/TCM" connector.
3. Measure resistance between "RED SOLENOID POWER" terminal of the ATM SOLENOID VALVE harness connector and "RED SOLENOID POWER" terminal of the PCM/TCM harness connector.

Specification :Approx. 0 Ohms








4. Is resistance within specifications?






Signal Circuit Inspection

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

Specification :Approx. 0 Ohms








(4) Is resistance within specifications?





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

Specification :Infinite








(4) Is resistance within specifications?
