Circuit Description

WARNING: This page is about a different car, the 2003 Pontiac Sunfire and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) controls the automatic transmission shift lock control solenoid. Battery positive voltage is supplied to the automatic transmission shift lock control solenoid. The BCM controls the automatic transmission shift lock control solenoid ground circuit. When the driver pressed the brake pedal the BCM removes the ground for the automatic transmission shift lock control solenoid. The solenoid de-energizes and releases the mechanical lock allowing the shift lever to be moved out of the PARK position.
