WARNING: This page is about a different car, the 2008 GMC Yukon and 2008 Chevrolet Tahoe. However, it is still accessible from the selected car via links, so may be relevant.

The scan tool data parameter PC 4 Sol. CKT Status normally displays 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 and if no concerns are found replace the control solenoid (w/body and TCM) valve assembly.
