DTC C1432 Steering Angle Sensor Power Source Voltage Malfunction


DESCRIPTION

Steering angle sensor (Spiral with sensor cable sub-assembly) signals are sent to the skid control ECU (master cylinder solenoid) 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.

INSPECTION PROCEDURE

NOTICE:
  1. When replacing the steering angle sensor (spiral with sensor cable sub-assembly), confirm that the replacement part is of the correct specification.
  2. Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
When the speed sensor or the yaw rate and acceleration sensor (airbag sensor assembly) has trouble, DTCs for the steering angle sensor (spiral with sensor cable sub-assembly) may be stored even when the steering angle sensor is normal. When DTCs for the speed sensor or yaw rate and acceleration sensor (airbag sensor assembly) are output together with DTCs for the steering angle sensor (spiral with sensor cable sub-assembly), inspect and repair the speed sensor and yaw rate and acceleration sensor (airbag sensor assembly) first, and then inspect and repair the steering angle sensor (spiral with sensor cable sub-assembly).
