Brake Shift Interlock System

The brake shift interlock system prevents moving the selector lever from the PARK position until the brake pedal is applied. The brake shift interlock system consists of a Brake Shift Interlock Actuator (BSIA) mounted on the selector lever. When the ignition switch is in the RUN position and the selector lever is in PARK, the BSIA  is energized when the brake pedal is applied. This will allow the selector lever to be moved from the PARK position.

If the selector lever will not move out of the PARK position with the key in the ON position and the brake pedal applied, it will need to be unlocked manually. For additional information, refer to BRAKE SHIFT INTERLOCK OVERRIDE .
