CAUTION / NOTICE / HINT

Note

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

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (POWER SOURCE TERMINAL)


    1. B002EV6C33
      *a

      Front view of wire harness connector

      (to Steering angle sensor (Spiral cable with sensor sub-assembly))

      Remove the steering wheel and column cover.

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

    3. Disconnect the K28 steering angle sensor (spiral cable with sensor sub-assembly) connector.

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      K28-8 (BAT) - Body ground Always 11 to 14 V
      K28-4 (IG1) - Body ground Engine switch on (IG) 11 to 14 V
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)

    OK

  2. CHECK HARNESS AND CONNECTOR (GROUND TERMINAL)


    1. B002EV6C34
      *a

      Front view of wire harness connector

      (to Steering angle sensor (Spiral cable with sensor sub-assembly))

      Turn the engine switch off.

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

      Note

      Before measuring the resistance of the steering angle sensor (spiral cable with sensor sub-assembly), turn the engine 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
      K28-1 (ESS) - Body ground Always Below 1 Ω
      Result
      Proceed to
      OK
      NG
