Hi Abdullah,

If they performed diagnosis to ensure the sensor and wiring are okay, there is a chance it could be the ABS module itself. However, the wheel speed sensor and wiring must be checked before you do the ABS or you will not fix it.

Here is a guide on how to test the wheel speed sensor. This code is for the left front speed sensor:

Let me know if this doesn't make sense and I can clarify any questions you have. Thanks.
