VEHICLE STABILITY CONTROL SYSTEM(for TMC Made), Diagnostic DTC:C1432

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

DESCRIPTION

Steering angle 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 angle sensor zero point malfunction diagnostic function.

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

  • Steering angle sensor power supply

  • Steering angle sensor (Spiral cable sub-assembly)

WIRING DIAGRAM

A01VLCUE01

CAUTION / NOTICE / HINT

Note


  • Do not remove the steering sensor from the spiral cable.

  • When replacing the spiral cable, 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 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 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 cable sub-assembly).

PROCEDURE


  1. CHECK TERMINAL VOLTAGE (BAT TERMINAL)


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

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

    3. Disconnect the steering angle sensor connector.
