Test C: DTCS C2797, C2798, C2800, C2801 and C2803 - Brake Pressure Transducer Circuit Failure
PINPOINT TEST C: DTCs C2797, C2798, C2800, C2801 AND C2803 - BRAKE PRESSURE TRANSDUCER CIRCUIT FAILURE
Normal Operation
The brake pressure transducer is attached to the brake master cylinder and they are serviced as an assembly. The transducer provides the trailer brake
control (TBC) module with the current brake pressure information. The TBC module supplies voltage to the transducer along circuit 3602 (TN/YE)
and ground along circuit 3600 (RD/WH). The voltage returned from the transducer along circuit 3601 (WH/RD) is used by the TBC module to
determine current brake pressure.
