VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1432

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

DESCRIPTION

The skid control ECU (brake actuator assembly) outputs this DTC when it receives a sensor power source malfunction signal from the steering angle sensor.

DTC No. DTC Detection Condition Trouble Area
C1432 Steering angle sensor power supply malfunction signal is received from steering angle sensor.

  • ECU-B fuse

  • ECU-IG NO. 2 fuse

  • Steering angle sensor (Spiral with sensor cable sub-assembly)

  • Wire harness or connector

WIRING DIAGRAM

B007VA4E01

INSPECTION PROCEDURE

Note


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

  • When replacing the steering angle sensor (spiral with sensor 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 U0073, U0124 and/or U0126 is output together with C1432, inspect and repair the trouble areas indicated by U0073, U0124 and/or U0126 first Click here.

  • When the speed sensor or the yaw rate sensor (airbag sensor assembly) has trouble, DTCs for the steering angle sensor (spiral with sensor cable sub-assembly) may be output even when the steering angle sensor is normal. When DTCs for the speed sensor or yaw rate 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 sensor (airbag sensor assembly) first, and then inspect and repair the steering angle sensor (spiral with sensor cable sub-assembly).

PROCEDURE


  1. CHECK TERMINAL VOLTAGE (POWER SOURCE CIRCUIT)


    1. Turn the ignition switch off.

      (to Steering Angle Sensor (Spiral with Sensor Cable Sub-assembly))

      Remove the steering wheel and the column cover.

    3. Make sure that there is no looseness at the locking part and the connecting part of the connector.

    4. Disconnect the H92 steering angle sensor (spiral with sensor cable sub-assembly) connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      H92-5 (BAT) - Body ground Always 11 to 14 V
      H92-4 (IG) - Body ground Ignition switch ON 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)

    OK

  2. CHECK HARNESS AND CONNECTOR (ESS TERMINAL)

      Turn the ignition switch off.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      H92-1 (ESS) - Body ground Always Below 1 Ω
