C1241 - FAULT CODE - OBD2

C1241 BUICK, CADILLAC, CHEVROLET, GMC, PONTIAC: VARIABLE EFFORT STEERING CIRCUIT MALFUNCTION

The VES (Variable Effort Steering) System is used by the EBCM (Electronic Brake Control Module) to provide a control and feedback circuit for the VES actuator. A 0-619 mA voltage signal is sent from the EBCM, taking into account the voltage input received by the vehicle’s speed and steering position sensor. The control and return currents are compared by the EBCM to detect possible faults in the operation of the VES actuator or the VES actuator circuitry.

DTC C1241 OBDII for Buick, Cadillac, Chevrolet, GMC, and Pontiac vehicles is set when a malfunction is detected by the Variable Torque Steering system circuit.

• Check Engine light ON.
• The Anti-lock Braking System (ABS) warning turns on.

The C1241 OBD2 fault code C1241 is set for one of the following reasons:

• The wiring of the Variable Strain Steering actuator may be damaged.
• The VES actuator circuit may be shorted.
• The Variable Effort Steering actuator may be in poor condition.
• The EBCM may have shortcomings.

The steps to follow to correct the C1241 OBDII diagnostic code are:

• As a first step, we recommend that you consult the Technical Service Bulletins.
• Check the Variable Strain Steering actuator wiring for damage due to corrosion or burns. If one of these conditions is discovered, make repairs or changes as required.
• Check the VES actuator circuit for shorts or damage to the actuator. Follow the manufacturer's recommendations to carry out this diagnosis and if any inconsistencies are detected, make the necessary corrections.
