      DTCs C051D-54 and/or C1210-54 are output. B

    Result: 

    A 

    END 

    Result: 

    B 

    See step  4

  4. CHECK YAW RATE AND ACCELERATION SENSOR INSTALLATION 
    1. Turn the engine switch off.
    2. Check that the yaw rate and acceleration sensor has been installed properly.

      Refer to INSTALLATION [09/2014 - ]

      OK

      The yaw rate and acceleration sensor should be tightened to the specified torque.

      The yaw rate and acceleration sensor should not be installed in a tilted position.

      Result

      Proceed to
      OK
      NG

    Result: 

    NG 

    INSTALL YAW RATE AND ACCELERATION SENSOR CORRECTLY. Refer to  INSTALLATION [09/2014 - ] 

    Result: 

    OK 

    See step  5

  5. READ VALUE USING TECHSTREAM (YAW RATE AND ACCELERATION SENSOR) 
    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Enter the following menus: Chassis / Brake / Data List.

      Chassis > Brake > Data List
