BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1433: Steering Angle Sensor Internal Circuit
C1433 - Steering Angle Sensor Internal Circuit

DESCRIPTION

Steering angle sensor signals are sent to the skid control ECU via the CAN communication system. When there is a malfunction in the CAN communication system, it is detected by the steering angle sensor zero point malfunction diagnostic function.





WIRING DIAGRAM

Refer to DTC C1432 C1432.

INSPECTION PROCEDURE

HINT
* When any of the speed sensors or the yaw rate and acceleration sensor has trouble, DTCs for the steering angle sensor may be stored even when the steering angle sensor is normal. When DTCs for the speed sensors or yaw rate and acceleration sensor are output together with DTCs for the steering angle sensor, inspect and repair the speed sensor and yaw rate and acceleration sensor first, and then inspect and repair the steering angle sensor.

PROCEDURE

1. CHECK DTC

(a) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
