C2807 Code: Meaning, Causes, and Symptoms | OBD2 Codes

C2807 – Trailer Brake Output Circuit Short To Ground

 

C2807 Possible Symptoms

 

Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)

 

C2807 Possible Causes

 

Faulty Trailer Brake Control (TBC) Module,Trailer Brake Control (TBC) Module harness is open or shorted,Trailer Brake Control (TBC) Module circuit poor electrical connection

 

C2807 Description

 

The braking energy that is provided to the trailer is varied with a Pulse Width Modulated (PWM) signal along the circuit that switches between 0 volt and battery voltage, the higher the duty cycle the more braking power available. The Trailer Brake Control (TBC) Module varies the PWM signal based on various inputs such as the brake pressure transducer, TBC module manual slider switch and the TBC module gain buttons. With the vehicle stationary and with the manual slider switch fully to the left with a gain of 10, there should be greater than 10-12 volts supplied to pin 3 of the 7-pin trailer tow connector. Every 4 seconds the TBC module sends a voltage pulse along circuit CAT19 (BU) to pin 3 of the 7-pin trailer tow connector to determine whether or not a trailer is connected.

C2795 Code: Meaning, Causes, and Symptoms | OBD2 Codes

C2795 – Brake Assist Unable To Initialize

 

C2795 Possible Symptoms

 

Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)

 

C2795 Possible Causes

 

Faulty Brake Pressure Transducer,Brake Pressure Transducer harness is open or shorted,Brake Pressure Transducer circuit poor electrical connection,Faulty Trailer Brake Control (TBC) Module

 

C2795 Description

 

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.
