DTC C1210/36: Zero Point Calibration of Yaw Rate Sensor Undone; DTC C1336/98: Zero Point Calibration of Acceleration Sensor Undone [08/2013 - ]: Description

WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.

The skid control ECU (brake booster with master cylinder assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via the CAN communication system.

The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition using 2 circuits (GL1, GL2).

If there are any problems in the bus lines between the yaw rate and acceleration sensor (airbag sensor assembly) 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 stored.

These DTCs (C1210/36 and C1336/98) will also be stored when zero point calibration has not been completed.

DTC No.	INF Code	DTC Detection Condition	Trouble Area
C1210/36	-	Yaw rate sensor zero point calibration is incomplete.	Zero point calibration undone Yaw rate sensor (Airbag sensor assembly) Skid control ECU (Brake booster with master cylinder assembly) (Perform zero point calibration and check for DTCs. If no DTCs are output again, the sensor is normal.)
C1336/98	-	Either of the following is detected: The vehicle is driven normally without zero point calibration completed. After completing zero point calibration, zero point voltage of the sensor is not within the range of 2.38 to 2.62 V.	Zero point calibration undone Acceleration sensor (Airbag sensor assembly) Skid control ECU (Brake booster with master cylinder assembly) (Perform zero point calibration and check for DTCs. If no DTCs are output again, the sensor is normal.)
