DTC C1210/36: Zero Point Calibration of Yaw Rate Sensor Undone; DTC C1336/98: Zero Point Calibration of Acceleration Sensor Undone [03/2017 - 09/2018]: Procedure

1. Perform zero point calibration of the yaw rate sensor.

   Refer to CALIBRATION [03/2017 - 05/2023]

   NOTE:

   Make sure to perform initialization and calibration of the linear solenoid valve after performing "Reset Memory" as the data stored during linear solenoid valve offset learning is cleared.

   HINT: 

   • When the stored zero point of the yaw rate sensor is cleared, steering sensor zero point will also be cleared.
   • If the zero point and output value of the yaw rate sensor and the output value of the speed sensors are not normal, steering sensor zero point cannot be acquired normally even if the vehicle is driven straight ahead at 35 km/h (22 mph) or more.
