VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1432

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

DESCRIPTION

This DTC is stored when the skid control ECU (brake actuator assembly) receives a +B line open signal from the steering angle sensor (spiral with sensor cable sub-assembly).

DTC No. DTC Detection Condition Trouble Area
C1432 With the +BS terminal voltage between 9.6 and 16.5 V, a steering angle sensor power supply circuit malfunction signal is received from the steering angle sensor.

  • Steering angle sensor (spiral with sensor cable sub-assembly) power supply

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

CAUTION / NOTICE / HINT

Note

Inspect the fuses for circuits related to this system before performing the following procedure.

PROCEDURE


  1. CHECK TERMINAL VOLTAGE (BAT TERMINAL)


    1. Turn the ignition switch off.

    2. Remove the steering wheel and column cover.

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

    4. Disconnect the D166 steering angle sensor (spiral with sensor cable sub-assembly) connector.

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

      Note

      Before measuring the resistance of the steering angle sensor, turn the ignition switch off and leave the vehicle for 1 minute or more without operating the key or switches, or opening or closing the doors.

      Standard Resistance
      Tester Connection Condition Specified Condition
      D166-2 (ESS) - Body ground 1 minute after turning ignition switch off Below 1 Ω
