Component Location





General Description

The Wheel Speed Sensors (WSS)are an essential component the ABS system. The WSS signals are used to calculate vehicle speed and to determine whether wheel lock occurs.
The Wheel Speed Sensors are active hall-sensor type.

DTC Description

The ABS ECU monitors the wheel speed sensor signal continuously.
This code is set when the sensor air gap is out of specified range or when the ABS control cycle is continued abnormally.
The HECU checks for air gap malfunctioning by monitoring the sensor signal at speeds between 2Km/h to 10 Km/h.
Warning lamp is turned OFF unless additional faults are detected when the IG KEY is turned ON again, and wheel speed is more than 10 Km/h (6.2mph).
