Solution

1. Preparation

Gather tools and parts needed for repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace the ABS Fuse

Locate the fuse box under the dashboard or hood.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse with a fuse puller or pliers and inspect it for continuity.
Replace the fuse with a new one of the same amperage if it is blown.

3. Inspect and Clean Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor's electrical connector.
Clean the sensor and the area around it to remove debris.
Reconnect the sensor and reinstall the wheel. Repeat for all wheels.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, add the manufacturer's recommended brake fluid type.
If the fluid is contaminated, flush the brake system and replace with new fluid.

5. Inspect ABS Module and Wiring

Locate the ABS module, typically near the master cylinder.
Visually inspect for any signs of leaks, corrosion, or damage to the wiring harness.
Repair or replace any damaged components as necessary.

6. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light is still illuminated.
Conduct a test drive to ensure the ABS system is functioning correctly.
