C1231
DTC C1231/31 Steering Angle Sensor Circuit MalfunctionDESCRIPTION
DTC DETECTION CONDITION:
The skid control ECU inputs the steering angle sensor signal through the CAN communication. When a malfunction occurs in the communication line with the steering angle sensor, DTC U0126/63 (malfunction in communication with steering angle sensor) is output.
WIRING DIAGRAM:
HINT:
^ When U0126/63 is output together with C1231/31, inspect and repair the trouble areas indicated by U0126/63 first.
^ When the speed sensor or the yaw rate and deceleration sensor has trouble, DTCs for the steering angle sensor may be output even when the steering angle sensor is normal. When DTCs for the speed sensor or yaw rate sensor are output together with other DTCs for the steering angle sensor, inspect and repair the speed sensor and yaw rate and deceleration sensor first, and then inspect and repair the steering angle sensor.
