ABS/ESC
C1647 CAN Hardware Error - Sensor Channel - General Information

Component Location





General Description

When the vehicle is turning, the yaw rate sensor detects the yaw rate electronically by the vibration change of plate fork inside the yaw rate sensor. If the yaw velocity reaches the specific velocity after it detects the vehicle's yawing, the ESC control is reactivated. The lateral G sensor senses the vehicle's lateral acceleration. A small element inside the sensor is attached to a deflectable leverarm by lateral acceleration. Direction and magnitude of lateral acceleration loaded to vehicle can be known by electrostatic capacity changing according to lateral acceleration. It interchanges signals with HECU through extra CAN line which is only used for communication between HECU and the sensor.

DTC Description

The HECU checks the sensor CAN H/W for normal ESC control, and sets this code if a sensor CAN H/W malfunction is detected.
