Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery before working on electrical components.

2. Inspect and Clean ABS Wheel Speed Sensors

Remove the wheel and tire to access the ABS wheel speed sensors.
Clean each sensor with a soft cloth and suitable cleaner to remove dirt and debris.
Inspect the wiring for any signs of fraying or damage, repairing or replacing as necessary.

3. Test and Replace ABS Fuse

Locate the ABS fuse in the fuse box (consult the owner’s manual for exact location).
Use a multimeter to check for continuity in the fuse.
If the fuse is blown, replace it with a fuse of the same amperage.

4. Brake Fluid Check and Replacement

Inspect the brake fluid reservoir for proper fluid level; add fluid if low.
If brake fluid is dirty or contaminated, perform a brake fluid flush and replace with manufacturer-approved fluid.

5. Reconnect Battery and Test Drive

Reconnect the battery terminals.
Start the vehicle and perform a test drive to ensure the ABS light is off and the system functions correctly.
