Inspection Procedure

NOTE:

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 source voltage drops when the battery is removed, and confirm that this condition occurred.

HINT:

When DTC U0073/94, U0123/62, U0124/95 and/or U0126/63 is output together with DTC C1439/66 and/or C1445/66, inspect and repair the trouble areas indicated by DTC U0073/94, U0123/62, U0124/95 and/or U0126/63 first, refer to DTC U0073/94: Control Module Communication Bus OFF; DTC U0123/62: Lost Communication with Yaw Rate Sensor Module; DTC U0124/95: Lost Communication with Lateral Acceleration Sensor Module; DTC U0126/63: Lost Communication with Steering Angle Sensor Module; DTC U0293/59: Communication Error from HV ECU .
When the speed sensor or the yaw rate and acceleration 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 the yaw rate and acceleration sensor are output together with other DTCs for the steering angle sensor, inspect and repair the speed sensor and the yaw rate and acceleration sensor first, and then inspect and repair the steering angle sensor.
