DTC C1210/36 Zero Point Calibration of Yaw Rate Sensor Undone; DTC C1336/98 Zero Point Calibration of Acceleration Sensor Undone: Description

WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.

The skid control ECU receives signals from the yaw rate and acceleration sensor through 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 is trouble 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) are output

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

DTC DETECTION CONDITION

DTC Code	DTC Detection Condition	Trouble Area
C1210/36	Vehicle is driven with zero point calibration of yaw rate sensor undone	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	Either of the following is detected The vehicle is driven 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 V and 2 62 V	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)
