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)

      *a

      Front view of wire harness connector

      (to Steering Angle Sensor)

      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.

      OK
      The connector is securely connected.

    3. Disconnect the I58 steering angle sensor connector.

    4. Check both the connector case and the terminals for deformation and corrosion.

      OK
      No deformation or corrosion.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      I58-5 (BAT) - Body ground Always 11 to 14 V
      I58-4 (IG1) - Body ground Power 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 (GND TERMINAL)


    1. A003O6TC33
      *a

      Front view of wire harness connector

      (to Steering Angle Sensor)

      Turn the power 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, turn the power 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
      I58-1 (ESS) - Body ground 1 minute after power switch off Below 1 Ω
      Result
      Proceed to
      OK
      NG

    OK
