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. CHECK DTC (CAN COMMUNICATION SYSTEM) 
    1. Check for DTCs (Refer to DTC CHECK / CLEAR [08/2015 - 08/2019] ).
      RESULT

      Result Proceed to
      CAN DTC is not output A
      CAN DTC is output B

    Result: 

    GO TO CAN COMMUNICATION SYSTEM (HOW TO PROCEED WITH TROUBLESHOOTING) 

    (Refer to HOW TO PROCEED WITH TROUBLESHOOTING [08/2015 - 08/2019] )

    Result: 

    See step  2

  2. 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  3

  3. PERFORM TEST MODE (SIGNAL CHECK) 
    1. Turn the ignition switch off.
    2. Perform the signal 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  4

  4. CHECK YAW RATE AND ACCELERATION SENSOR INSTALLATION 
    1. Turn the ignition switch off.
    2. Check that the yaw rate and acceleration sensor has been 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  5

  5. 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.: -18.183 m/s2 , Max.: 18.183 m/s2 - Changes continuously during acceleration/deceleration.
      Deceleration Sensor2 Acceleration sensor 2/ Min.: -18.183 m/s2 , Max.: 18.183 m/s2 - Changes continuously during acceleration/deceleration.
      Yaw Rate Sensor Yaw rate sensor/ Min.: -128°/s, Max.: 127°/s Vehicle stationary: 0°/s
      Right turn: -128 to 0°/s
      Left turn: 0 to 127°/s
      -
      Yaw Rate Sensor2 Yaw rate sensor 2/ Min.: -128°/s, Max.: 127°/s Vehicle stationary: 0°/s
      Right turn: -128 to 0°/s
      Left turn: 0 to 127°/s
      -
    6. Check that the yaw rate and acceleration sensor output value is 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 MASTER CYLINDER SOLENOID 

    (Refer to DISASSEMBLY [08/2015 - ] )

    Result: 

    NG 

    REPLACE YAW RATE AND ACCELERATION SENSOR 

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