Shift Interlock Systems: Description

WARNING: Vehicle is equipped with Supplemental Inflatable Restraint (SIR) system. When servicing vehicle, use care to avoid accidental air bag deployment. SIR system-related components are located in various locations throughout interior and exterior of vehicle, depending on application. Do not use electrical test equipment on or near these circuits. If necessary, deactivate SIR system before servicing components. See AIR BAG DEACTIVATION PROCEDURES article in GENERAL INFORMATION.

The automatic transmission shift lock control system prevents the driver from shifting out of Park without depressing the brake pedal. The shift lock control solenoid is provided battery voltage when the ignition is in the ON position and the vehicle is in Park. The shift lock control solenoid is mounted near the floor shifter in the front floor console, and mechanically locks the shifter from moving. When pressure is applied to the brake pedal, the shift lock control solenoid is energized and releases the locking tab on the floor shifter.
