DTC C1210/36 Zero Point Calibration of Yaw Rate Sensor Undone; DTC C1336/39 Zero Point Calibration of Acceleration Sensor Undone: Description

The skid control ECU receives signals from the yaw rate and acceleration sensor via the CAN communication system.

The yaw rate sensor has the built in acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2). If there is trouble in the bus lines between the yaw rate and acceleration sensor and the CAN communication system, the DTCs U0123/62 (yaw rate sensor communication trouble) and U0124/95 (acceleration sensor communication trouble) are output.

The DTCs are also output when the calibration has not been completed.

DTC DETECTION CONDITION CHART

DTC Code	DTC Detection Condition	Trouble Area
C1210/36	Zero point calibration of yaw rate sensor undone.	Brake actuator assembly (Skid control ECU) Yaw rate and acceleration sensor Zero point calibration undone (Perform zero point calibration and check DTC. If DTC is not output again, the sensor is normal)
C1336/39	When either of the following is detected: The vehicle runs in the normal mode with zero point calibration undone. After the zero point has been obtained, the zero point voltage of the sensor is not between 2.38 and 2.62 V.	Brake actuator assembly (Skid control ECU) Yaw rate and acceleration sensor Zero point calibration undone (Perform zero point calibration and check DTC. If DTC is not output again, the sensor is normal)
