DTC C1285-04: Uncalibrated Ax Signal: General Description

The yaw rate sensor, lateral G sensor, longitudinal G sensor are packaged in the IMU (Inertial Measurement Unit).

If the yaw velocity reaches a certain point after IMU detects the vehicle's yawing, the ESP (ESC) control is activated.

IMU is installed in SRSCM and it interchanges signals with ESP (ESC) through extra CAN line which is only used for communication between IBAU and the IMU.
