The Brake Pressure Transducer is attached to the brake master cylinder and is hardwired to the Trailer Brake Control (TBC) Module. The transducer and the master cylinder are installed new as an assembly. The TBC module supplies voltage to the transducer and ground along circuits. The voltage returned from the transducer and is used by the TBC module to determine current brake pressure. Trailer Brake Control (TBC) Module sets the OBDII code when the Brake Pressure Transducer is not to factory specifications.
