Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shorts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.

2. Inspect and Replace ABS Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.
Reconnect the fuse and check if the ABS light turns off.

3. Clean or Replace Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel.
Clean the sensors and their connectors with electrical cleaner to remove dirt and debris.
If damaged, replace the wheel speed sensors with new ones, ensuring proper alignment and securing them in place.

4. Check Brake Fluid and Brake Lines

Inspect the brake fluid reservoir for proper fluid level; top off with manufacturer-recommended brake fluid if low.
Check the brake lines for any visible leaks or damage; replace any faulty lines immediately.

5. Test and Reprogram ABS Module (if necessary)

If all previous checks are clear, connect the OBD-II scanner to the vehicle and check for ABS module error codes.
If needed, reprogram the ABS module following the manufacturer's guidelines; this may require specialized equipment.

6. Reconnect Battery and Reset ABS System

After completing repairs, reconnect the vehicle's battery.
Use the OBD-II scanner to clear any ABS error codes and reset the ABS system.
Test the vehicle to ensure the ABS light is off and the system is functioning correctly.
