Brake Pedal Position (BPP) Switch

The Brake Pedal Position (BPP) switch is mounted on the brake pedal bracket.

It switches the stoplights on and tells the PCM when the brakes are applied.

The signal of the Brake Pedal Position (BPP) switch is received by the TCM from the PCM and used for the following functions:

• to release the TCC when the brake pedal is depressed.
• to switch off the selector lever shift lock when the brake pedal is depressed in P.

No substitute signal is available for the BPP switch.

If the connection to the BPP switch is cut, the selector lever cannot be moved out of P.
