Circuit/System Testing
- Ensure the transmission fluid temperature is between 50-80°C (122-176°F).
- Operate the vehicle in 2nd gear long enough to ensure at least a 3°C (5°F) rise in TCM temperature, then operate the vehicle in Park for 5 seconds.
- Observe the scan tool data parameter Line PC Sol. CKT Status, the parameter should display OK.
- If the parameter displays Open, Short to Volts, Short to GND or if the DTC resets, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection .
- If no concerns are found during the inspection, replace the control solenoid (w/body and TCM) valve assembly.
