Brake Switch (Cruise Control): Description and Operation
Brake Pedal Position (BPP) Switch
BRAKE PEDAL POSITION (BPP) SWITCH
Typical BPP Switch
The BPP switch is sometimes referred to as the stoplamp switch. The BPP switch provides a signal to the PCM indicating that the brakes are applied.
The BPP switch is normally open and is mounted on the brake pedal support. Depending on the vehicle application the BPP switch can be hardwired as
follows:
-
BPP switch is hardwired to the PCM supplying battery positive voltage (B+) when the vehicle brake pedal is applied.
-
BPP switch is hardwired to the Anti-Lock Brake System (ABS) Module, Lighting Control Module (LCM), or Rear Electronic Module (REM), the
BPP signal is then broadcast over the network to be received by the PCM.
-
BPP switch is hardwired to the anti-lock brake system (ABS) traction control/stability assist module. The ABS module interprets the BPP switch
input along with other ABS inputs and generates an output called the driver brake application (DBA) signal. The DBA signal is then sent to the
PCM and to other BPP signal users.
