VEHICLE STABILITY CONTROL SYSTEM (for Vacuum Brake Booster), Diagnostic DTC:C1432

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

DESCRIPTION

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

DTC Code DTC Detection Condition Trouble Area
C1432 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 circuit

  • Steering angle sensor (Spiral cable sub-assembly)

INSPECTION PROCEDURE

Note


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

  • 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.

Tech Tips


  • When DTC U0073, U0123, U0124 and/or U0126 is output together with DTC C1432, inspect and repair the trouble areas indicated by DTC U0073, U0123, U0124 and/or U0126 first Click here.

  • 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.

PROCEDURE


  1. CHECK TERMINAL VOLTAGE (BAT)


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

    2. Disconnect the G33 steering angle sensor connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      G33-6 (BAT) - Body ground Always 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK TERMINAL VOLTAGE (IG)


    1. Disconnect the G33 steering angle sensor connector.

      G33-5 (IG) - Body ground Ignition switch ON 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. CHECK HARNESS AND CONNECTOR (ESS CIRCUIT)


    1. Disconnect the G33 steering angle sensor connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      G33-2 (ESS) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK
