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