Shift Interlock Systems: Description

WARNING: Vehicles are equipped with Supplemental Inflatable Restraint (SIR) systems. See AIR BAG SERVICE PRECAUTIONS article in APPLICATIONS & IDENTIFICATION before attempting adjustments or repairs on or around steering column and components.

The transmission shift interlock system prevents driver from moving gear selector from Park unless ignition switch is turned to ON position, and also prevents ignition key from being removed until gear selector is returned to Park. Brake Transmission Shift Interlock (BTSI) solenoid locks gear selector in Park while ignition is on until brake pedal is depressed. This prevents accidental movement of gear selector from Park while engine is running. BTSI solenoid is located on floor shifter.
