VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1432

DTC Code DTC Name
C1432 Steering Angle Sensor Power Source Voltage Malfunction

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.

DTC No.

Steering Angle Sensor Power Source Voltage Malfunction

A steering angle sensor power supply malfunction signal is received from the steering angle sensor.

  • ECU-B fuse

  • ECU-IG NO. 1 fuse

  • Steering angle sensor power supply

  • Steering angle sensor (Spiral cable sub-assembly)

WIRING DIAGRAM

C200080E25

CAUTION / NOTICE / HINT

Note:

  • Do not remove the steering angle sensor from the spiral cable.

  • When replacing the spiral cable sub-assembly, confirm that the replacement part is of the correct specification.

  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

Tip:

When the speed sensor 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 sensor 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.
