INSPECTION PROCEDURE

Note

When replacing the yaw rate and acceleration sensor, perform zero point calibration Click here.

PROCEDURE


  1. CHECK YAW RATE AND ACCELERATION SENSOR INSTALLATION


    1. Check that the yaw rate and acceleration sensor has been installed properly Click here.

      OK
      The sensor is tightened to the specified torque.
      The sensor is not installed in a tilted position.

    NG

    INSTALL YAW RATE AND ACCELERATION SENSOR CORRECTLY Click here

    OK

  2. INSPECT YAW RATE AND ACCELERATION SENSOR (IG TERMINAL)

      (to Yaw Rate and Acceleration Sensor)

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

    2. Disconnect the yaw rate and acceleration sensor connector.

    3. Turn the engine switch on (IG).

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      J115-4 (IG) - Body ground Engine switch on (IG) 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (IG CIRCUIT)

    OK

  3. INSPECT YAW RATE AND ACCELERATION SENSOR (GND TERMINAL)

      Turn the engine switch off.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      J115-1 (GND) - Body ground Always Below 1 Ω

      Note

      Check the yaw rate and acceleration sensor signal after replacement Click here.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (GND CIRCUIT)

    OK
