DTC C1210: Zero Point Calibration of Yaw Rate Sensor Undone; DTC C1336: Zero Point Calibration of Acceleration Sensor Undone [08/2015 - 08/2019]: Procedure

  1. PERFORM ZERO POINT CALIBRATION OF YAW RATE AND ACCELERATION SENSOR 
    1. Perform zero point calibration of the yaw rate and acceleration sensor (Refer to CALIBRATION [08/2015 - 08/2019] ).

    Result: 

    NEXT 

    See step  2

  2. PERFORM TEST MODE (SIGNAL CHECK) 
    1. Turn the ignition switch off.
    2. Perform the sensor check in the test mode procedure (Refer to TEST MODE PROCEDURE [08/2015 - 08/2019] ).

      OK

      All test mode DTCs are cleared.

    Result: 

    OK 

    END 

    Result: 

    NG 

    See step  3

  3. CHECK YAW RATE AND ACCELERATION SENSOR INSTALLATION 
    1. Turn the ignition switch off.
    2. Check that the yaw rate and acceleration sensor is installed properly (Refer to INSTALLATION [08/2015 - 08/2019] ).

      OK

      The sensor is tightened to the specified torque.

      The sensor is not installed at an angle.

    Result: 

    NG 

    INSTALL YAW RATE AND ACCELERATION SENSOR CORRECTLY 

    (Refer to INSTALLATION [08/2015 - 08/2019] )

    Result: 

    OK 

    See step  4

  4. READ VALUE USING TECHSTREAM (YAW RATE AND ACCELERATION SENSOR) 
    1. Turn the ignition switch off.
    2. Connect the Techstream to the DLC3.
    3. Turn the ignition switch to ON.
    4. Turn the Techstream on.
    5. Enter the following menus: Chassis / ABS/VSC/TRAC / Data List.
      ABS/VSC/TRAC

      Tester Display Measurement
      Item/Range
      Normal Condition Diagnostic Note
      Deceleration Sensor Acceleration sensor/ Min.: -18.525 m/s2 , Max.: 18.387 m/s2 - Changes continuously during acceleration/deceleration.
      Deceleration Sensor2 Acceleration sensor 2/ Min.: -18.525 m/s2 , Max.: 18.387 m/s2 - Changes continuously during acceleration/deceleration.
      Yaw Rate Sensor Yaw rate sensor/ Min.: -128°/s, Max.: 127°/s Vehicle stopped: 0°/s
      Turning right: -128 to 0°/s
      Turning left: 0 to 127°/s
      -
    6. Check the yaw rate and acceleration sensor output value displayed on the Techstream.

      OK

      The yaw rate and acceleration sensor output value is normal.

      NOTE:

      Check the yaw rate and acceleration sensor signal after replacement (Refer to TEST MODE PROCEDURE [08/2015 - 08/2019] ).

    Result: 

    OK 

    REPLACE BRAKE ACTUATOR ASSEMBLY 

    (Refer to REMOVAL [08/2015 - 08/2019] )

    Result: 

    NG 

    REPLACE YAW RATE AND ACCELERATION SENSOR 

    (Refer to REMOVAL [08/2015 - 08/2019] )
