INSPECTION PROCEDURE

Tech Tips


  • 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 Click here.

  • When the speed sensor or the yaw rate and acceleration 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 acceleration sensor are output together with DTCs for the steering angle sensor, inspect and repair the speed sensor and yaw rate and acceleration sensor first, and then inspect and repair the steering angle sensor.

PROCEDURE


  1. INSPECT STEERING ANGLE SENSOR (POWER SOURCE TERMINAL)


    1. A017BFRE10

      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.

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

      Standard voltage
      Tester Connection Switch Condition Specified Condition
      D13-4 (IG1) - Body ground Ignition switch on (IG) 11 to 14 V
      D13-5 (BAT) - Body ground Always 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)

    OK

  2. INSPECT STEERING ANGLE SENSOR (GROUND TERMINAL)


    1. A017BFRE11

      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
      D13-1 (ESS) - Body ground Always Below 1 Ω
