INSPECT STEERING ANGLE SENSOR (GROUND TERMINAL)

DTC C1432 Steering Angle Sensor Power Source Voltage Malfunction


DESCRIPTION

Steering angle sensor signals are sent to the skid control ECU via the CAN communication system. When there is a malfunction in the CAN communication system, it is detected by the steering angle sensor zero point malfunction diagnostic function.

DTC Code
DTC Detection Condition
Trouble Area
C1432
Steering angle sensor power supply malfunction signal is received from steering angle sensor.
  1. Steering angle sensor power supply
  2. Steering angle sensor

INSPECTION PROCEDURE

HINT:
  1. When U0073, U0123, U0124 and/or U0126 is output together with C1432, inspect and repair the trouble areas indicated by U0073, U0123, U0124 and/or U0126 first (RAV4_ACA30 RM000000YUO0AQX.html).
  2. When the speed sensor or the yaw rate and deceleration sensor has trouble, DTCs for the steering angle sensor may be output even when the steering angle sensor is normal. When DTCs for the speed sensor or yaw rate and deceleration sensor are output together with DTCs for the steering angle sensor, inspect and repair the speed sensor and yaw rate and deceleration sensor first, and then inspect and repair the steering angle sensor.

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

  1. Make sure that there is no looseness in the locking part and connecting part of the connectors.

  1. Disconnect the steering angle sensor connector.

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

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    E95-4 (IG) - Body ground
    		Ignition switch ON
    		11 to 14 V
    E95-5 (BAT) - Body ground
    		Always
    		11 to 14 V

  1. Turn the ignition switch off.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    E95-1 (ESS) - Body ground
    		Always
    		Below 1 Ω
    HINT:
    If troubleshooting has been carried out according to the Problem Symptoms Table, refer back to the table and proceed to the next step (RAV4_ACA30 RM000000OS7035X.html).
