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 operation.
