Brake Shift Interlock System: Notes
WARNING: This page is about a different variant/trim than selected.
The BSIA (brake shift interlock actuator) inhibits the selector lever movement from the P 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/START position and the transmission in P, the BSIA is energized by the BCM, this allows the selector lever to be moved out of the P position.
