Circuit Description

WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 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. Positive voltage is supplied via the ignition 1 voltage circuit to the automatic transmission shift lock control solenoid. The BCM controls the ground circuit of the automatic transmission shift lock control solenoid. When the brake pedal is depressed, the BCM removes the ground allowing the solenoid to disengage. This action allows the vehicle to be shifted out of the PARK position.
