Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, basic socket set, replacement wheel speed sensors (if needed), brake cleaner, and safety gloves.
Ensure the vehicle is parked on a flat surface, and the ignition is off before starting work.

2. Check and Replace ABS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the ABS fuse by referring to the vehicle's manual.
Remove the fuse and visually inspect it for any signs of damage. If blown, replace it with one of the same amperage.

3. Inspect Wheel Speed Sensors

Raise the vehicle safely using jack stands and remove the wheel corresponding to the ABS warning.
Locate the wheel speed sensor on the brake assembly.
Clean any dirt or debris from the sensor and connector using brake cleaner.
If damaged, disconnect the sensor and remove it from the hub. Install a new sensor by reversing the removal process.

4. Check and Repair Hydraulic Unit

Inspect the ABS hydraulic unit for any signs of fluid leaks or physical damage.
If leaks are present, the hydraulic unit may need to be replaced. Follow manufacturer-specific guidelines for the replacement process.

5. Clear Error Codes and Test

Reconnect the OBD-II scanner to the vehicle and clear any stored ABS error codes.
Start the vehicle and check if the ABS light remains off.
Perform a test drive to ensure proper ABS functionality.
