ABS Diagnostics

The Anti-lock Braking System (ABS) prevents wheel lock-up during emergency braking, allowing the driver to maintain steering control. The system uses wheel speed sensors at each wheel to monitor rotation speed, and an ABS control module that modulates brake pressure to each wheel independently when it detects imminent lock-up. When the ABS warning light illuminates, the system has detected a fault and has disabled itself, reverting to conventional braking without anti-lock protection.

At Luxury Auto Care Dubai, we use manufacturer-level diagnostic equipment to read ABS fault codes, check live data from all wheel speed sensors, and test the ABS hydraulic actuator and control module. Common ABS faults include failed wheel speed sensors (often caused by contaminated or damaged reluctor rings), damaged wiring in the sensor harness, faulty ABS control modules, and hydraulic actuator valve failures. We check each component systematically to identify the root cause.

After diagnosis, we provide a detailed report showing the fault codes, affected components, and recommended repairs. Wheel speed sensor replacement is the most common ABS repair and can usually be completed within a few hours. For control module failures, we can reprogram or replace the module and perform the required system calibration. Every ABS repair includes a full system test to verify that all four wheel speed sensors are reading correctly and the ABS system activates when required.
