Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery negative terminal to prevent any electrical issues.

2. Check and Replace ABS Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Use a fuse puller or pliers to remove the ABS fuse.
Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.
Locate the wheel speed sensors mounted on the brake assembly.
Clean the sensors gently with a soft cloth to remove dirt and debris.
Check the wiring and connector for damage; repair as necessary.

4. Brake Fluid Check and Replacement

Inspect the brake fluid level in the master cylinder reservoir.
If low, top off with manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
If the fluid is contaminated, drain and replace it:
- Open the bleed valve on one wheel at a time and use a vacuum pump or gravity bleed method to replace old fluid.
- Ensure no air is trapped in the lines.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light remains illuminated.
Perform a test drive to ensure the ABS system functions correctly under braking.
