Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Addressing Fault Codes

Use an OBD-II scanner to read and document any ABS-related fault codes.
Clear the codes and perform a test drive to see if the ABS light reappears.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel.
Disconnect the electrical connectors and clean the sensor tips with brake cleaner.
Reconnect the sensors and ensure they are properly seated.

4. Check ABS Fuse

Locate the fuse box and find the ABS fuse (refer to the owner's manual for the exact location).
Remove the fuse and inspect it for damage; replace if necessary with the same amperage rating.

5. Examine Brake Fluid

Open the master cylinder reservoir cap and check the brake fluid level.
If low, top off with manufacturer-recommended brake fluid type (e.g., DOT 3 or DOT 4).
Inspect the brake lines for leaks and repair any found.

6. Test the ABS Module

Use a multimeter to check the voltage and ground connections to the ABS module.
If the module is faulty, replace it according to the manufacturer’s specifications.
