DTC C1210/36: Zero Point Calibration of Yaw Rate Sensor Undone; DTC C1336/98: 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 a built-in acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2).

If there are any problems in the bus lines between the yaw rate and acceleration sensor and the CAN communication system, DTCs U0123/62 (Lost Communication with Yaw Rate Sensor Module) and U0124/95 (Lost Communication with Lateral Acceleration Sensor Module) will be output.

The DTCs will also be output when calibration has not been completed.

DTC Code	INF Code	DTC Detection Condition	Trouble Area
C1210/36	336	Yaw rate sensor zero point calibration is unfinished.	Skid control ECU Yaw rate and acceleration sensor Zero point calibration undone (Perform zero point calibration and check for DTCs. If this DTC is not output again, the sensor is normal)
C1336/98	318	Either of the following is detected: The vehicle is driven in normal mode with zero point calibration unfinished. Zero point calculation is not within specified range (2.38 to 2.62 V) when zero point calibration is finished.	Skid control ECU Yaw rate and acceleration sensor Zero point calibration undone (Perform zero point calibration and check for DTCs. If this DTC is not output again, the sensor is normal)
