CUSTOMER CONCERN After a driver-side wheel impact and suspension repairs, DTCs C1231, C1A47, and C1626 remain stored for the steering-angle system. CAUSE The steering-angle sensor was confirmed faulty after the collision damage. CORRECTION Remove and replace the failed steering-angle sensor, clear DTCs C1231, C1A47, and C1626, and verify steering-angle data and system operation.

CUSTOMER CONCERN DTC C1231 repeatedly returns after curb-impact steering and suspension repairs, even after steering-angle calibration. CAUSE The confirmed repair identified a failed steering-angle sensor after power, ground, CAN communication, and calibration checks. CORRECTION Remove and replace the failed steering-angle sensor and perform the supported steering/yaw-rate calibration.

CUSTOMER CONCERN DTC C1231 returns immediately after clearing for a steering-angle-sensor fault. CAUSE The steering angle sensor failed after its battery feeds, ground, and CAN circuits were identified as the required checks. CORRECTION Remove and replace the failed steering angle sensor, perform the required steering-angle calibration, clear DTC C1231, and verify the code does not return.

CUSTOMER CONCERN After left steering-knuckle service, ABS DTC C1231 is stored and the steering-angle reading is fixed at 850 degrees. CAUSE The steering-angle sensor signal remained stuck at 850 degrees after CAN-bus, power, and ground checks, confirming a failed steering-angle sensor. CORRECTION Remove and replace the failed steering-angle sensor, perform the required steering-angle calibration, clear DTC C1231, and verify a responsive steering-angle reading and normal ABS o
