Brake Shift Interlock Operation
WARNING: This page is about a different car, the 2021 Ford Police Interceptor Utility. However, it is still accessible from the selected car via links, so may be relevant.
The brake shift interlock actuator inhibits the selector lever movement from the PARK position by mechanically blocking the detent pawl of the selector lever mechanism. When the brake pedal is pressed (BPP switch closed) with the ignition key in the RUN position and the transmission in PARK, the brake shift interlock actuator is energized by the BCM, allowing the selector lever to be moved out of the PARK position.
The brake shift interlock system consists of:
- a brake shift interlock actuator that is integral to the selector lever assembly.
- an ignition switch.
- a BPP switch.
- a BCM.
