P2763 Torque Converter Clutch Control Solenoid Valve Circuit High (SLU) - 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?






Control Circuit Inspection

1. Engine "OFF" IG KEY "OFF".
2. Disconnect solenoid valve connector.
3. Engine "OFF" IG KEY "ON"
4. Measure voltage between "Torque convertor clutch control solenoid valve (SLU)" terminal and chassis ground.

Specification : Approx. 2 V








5. Is voltage within specifications?






Ground Circuit Inspection

1. IG KEY "OFF".
2. Disconnect TCM connector.
3. IG KEY "ON" & Engine "OFF"
4. Measure the voltage between signal wiring of "Torque convertor clutch control solenoid valve (SLU)" and chassis ground.(Test 1)
5. Measure the voltage between signal wiring of "Torque convertor clutch control solenoid valve (SLU)" and ground circuit.(Test 2)

Specification : Teat1 - Test2 = below 200 mV

Test 1









Test 2








6. Is voltage within specifications?
