C0265

Electronic Brake Control Module Relay Circuit

The internal relay in the ABS module is malfunctioning — a very common sign of EBCM failure.

C0267 / C0268

Pump Motor Circuit Open/Short

The module can’t control the ABS pump motor properly (either open or shorted circuit).

C0241 / C0242

Engine Torque Reduction Signal Error

The ABS module isn’t communicating correctly with the engine or transmission control modules.

C0110

Pump Motor Circuit Malfunction

Fault in the ABS pump circuit (could be the motor, wiring, or the module driver).

C1214

Relay Contact or Valve Circuit Stuck

Internal relay or valve inside the EBCM is sticking or burned out.

C1221 – C1225

Wheel Speed Sensor Circuit Faults

The module detects irregular or missing signals from wheel speed sensors (could be sensors or module input failure).

C1233 / C1234

Wheel Speed Sensor Signal Missing

Indicates communication issues or internal signal processing faults in the EBCM.

C0261 / C0262

ABS Motor or Relay Power Circuit Low Voltage

Often due to internal power failure in the module.

U0100 / U0121

Lost Communication with ECM / EBCM

The module has lost data connection with other control units (CAN bus issue or internal module failure).
