The yaw-rate sensor and lateral and longitudinal G sensor [Yaw Sensor] is installed on the passenger seat under floor.
The Yaw Sensor detects acceleration of the vehicle around its vertical axis, while the G sensor detects lateral acceleration of the vehicle.
It sends messages to HECU through CAN communcation line.
The HECU checks the CAN communcation lines for normal ESP control, and sets this code if an Yaw Sensor message is not received within predefined time.
