DTC C1283-54: Lateral G Sensor/Longitudinal G Sensor/Yaw Rate Sensor - Signal Error: General Description
The yaw rate sensor, lateral G sensor, and longitudinal G sensor are packaged in the Inertial Measurement Unit (IMU).
If the yaw velocity reaches the specific velocity after IMU detects the vehicle's yawing, the ESC control is activated.
IMU is installed in SRSCM and it interchanges signals with IEB module through extra CAN line which is only used for communication between IEB module and the IMU.
