VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1432

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

DESCRIPTION

Spiral cable sub-assembly (steering sensor) signals are sent to the skid control ECU (brake actuator assembly) via the CAN communication system. When there is a malfunction in the CAN communication system, it will be detected by the steering sensor zero point malfunction diagnostic function.

DTC NO. DTC Detection Condition Trouble Area
C1432 Steering sensor power supply malfunction signal is received from spiral cable sub-assembly (steering sensor).

  • Steering sensor power supply

  • Spiral cable sub-assembly (steering sensor)

WIRING DIAGRAM

A005KP8E04

CAUTION / NOTICE / HINT

Note


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

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

PROCEDURE


  1. CHECK TERMINAL VOLTAGE (IG, BAT)

      (to Spiral Cable Sub-assembly (Steering sensor))

      Remove the steering wheel and the lower column cover.

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

    3. Disconnect the F30 spiral cable sub-assembly (steering sensor) connector.

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      F30-5 (IG) - Body ground Ignition switch ON 11 to 14 V
      F30-6 (BAT) - Body ground Always 11 to 14 V

    5. Reconnect the F30 spiral cable sub-assembly (steering sensor) connector.

    6. Reinstall the steering wheel and the lower column cover.
