Inspection Procedure

Before proceeding with the inspection, explain to the customer that the output DTC is related to temporary loss of the steering angle zero calibration, such as when the power voltage drops when the battery is removed, and confirm that this condition occurred.
When U0073/94, U0123/62, U0124/95 and/or U0126/63 is output together with C1231/31, inspect and repair the trouble areas indicated by U0073/94, U0123/62, U0124/95 and/or 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 and deceleration 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.
When the steering angle sensor and/or yaw rate deceleration sensor is replaced, perform zero calibration for the applicable sensor(s).
When replacing the brake actuator assembly, perform zero point calibration.
