DTC    C1432    Steering Angle Sensor Power Source Voltage Malfunction

for Preparation Click here


DESCRIPTION

Signals from the steering sensor (built in to the spiral cable) are sent to the skid control ECU (built in to the brake actuator assembly) through CAN communication.

DTC Code
DTC Detection Condition
Trouble Area
C1432
Steering angle sensor power supply malfunction signal is received from steering angle sensor.
  1. Steering angle sensor power supply
  2. Steering angle sensor (built into the spiral cable)

INSPECTION PROCEDURE

NOTICE:
  1. Do not remove the steering sensor from the spiral cable.
  2. When replacing the spiral cable, confirm that the replacement part is of the correct specification.
  3. Inspect the fuses for circuits related to this system before performing the following inspection procedure.

HINT:
  1. When U0073, U0123, U0124 and/or U0126 is output together with C1432, inspect and repair the trouble areas indicated by U0073, U0123, U0124 and/or U0126 first (Click here).
  2. 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 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.

1.INSPECT STEERING ANGLE SENSOR (BAT TERMINAL)

  1. Remove the steering wheel and the column cover lower.

  1. Make sure that there is no looseness at the locking part and the connecting part of the connectors.

  1. Disconnect the D20 steering angle sensor connector.

  1. Measure the voltage according to the value(s) in the table below.

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    D20-6 (BAT) - Body ground
    		Always
    		11 to 14 V
