Circuit/System Testing

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Ensure the transmission fluid temperature is between 50 and 80°C (122 and 176°F).
Operate the vehicle in M 1 long enough to ensure at least a 3°C (5°F) rise in TCM temperature.
Place the gear selector in D for 5 seconds and then idle vehicle for 5 seconds.
Observe the scan tool data parameter Shift Sol. 1 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.
