C1200 Wheel Speed Sensor Front-LH Open/Short - General Information

Component Location





General Description

The ESC system (It is equally said ESP system) is the shorten word of Electronic Stability Control system. This system recognizes a critical driving condition by Yaw-rate sensor, Lateral acceleration sensor and Steering angle sensor. And then it stabilizes the vehicle by a individual wheel braking and engine torque control through CAN communication. Among components of this system, the wheel speed sensor (WSS) is the essential component of the brake system. The ESC ECU (HECU, Hydraulic and Electronic Control Unit) uses the wheel speed sensor's signals to calculate a vehicle speed and also to determine whether a wheel lock occurs or not.

DTC Description

The HECU monitors the wheel speed sensor's circuit and If it's signal current is continuously out of the specified range, this DTC is set.
