Circuit Description

The brake actuator receives signals from the yaw rate sensor via the CAN communication system.

The yaw rate sensor has a built-in deceleration sensor.

If there is trouble in the bus lines between the yaw rate sensor and CAN communication system, the DTC U0123/62 (yaw rate sensor communication trouble) and U0124/95 (deceleration sensor communication trouble) are output.

YAW RATE SENSOR

DTC No.	DTC Detecting Condition	Trouble Area
C1210/36	Zero point calibration of yaw rate sensor undone	Yaw rate (deceleration) sensor Zero point calibration undone (Perform zero point calibration and check for a DTC. If DTC is not output again, the sensor is normal)
C1336/39	When any of the following (1 to 2) is detected: Drives in normal mode before completing zero point calibration. Zero point voltage is not within 2.38 V and 2.62 V at zero point calibration.	Yaw rate (deceleration) sensor Zero point calibration undone (Perform zero point calibration and check for a DTC. If DTC is not output again, the sensor is normal)
