DTC C1210: Zero Point Calibration of Yaw Rate Sensor Undone; DTC C1336: Zero Point Calibration of Deceleration Sensor undone [02/2019 - 12/2021]: 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 UTILITY [02/2019 - 12/2021]

      Result

      Result Proceed to
      DTCs C1210 and/or C1336 are output. A
      DTCs C1210 and C1336 are not output. B

      HINT: 

      • These DTCs are stored because zero point calibration has not been completed.
      • End the procedure if the same DTCs are not stored after completion of zero point calibration.

    Result: 

    B
