Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles.

2. Check and Replace ABS Fuse

Locate the fuse box, typically found in the engine compartment or under the dashboard.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the ABS fuse and check for continuity using a multimeter.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Inspect and Replace Wheel Speed Sensors

Lift the vehicle securely using a jack and jack stands.
Remove the wheel to access the brake components.
Locate the wheel speed sensor on the hub assembly.
Disconnect the sensor's electrical connector and remove the mounting bolt.
Inspect the sensor for damage or debris and replace it if necessary.
Reinstall the new sensor, reconnect the electrical connector, and reassemble the wheel.

4. Check and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the brake fluid level; if it’s low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect the brake lines for any signs of leaks or damage.

5. Inspect ABS Control Module

Locate the ABS control module, usually mounted on or near the master cylinder.
Check for any damaged wiring or corroded connectors.
If necessary, replace the ABS control module, ensuring to follow manufacturer specifications for installation.

6. Test Drive and Reset ABS Light

After repairs, reconnect the battery if it was disconnected.
Start the vehicle and check if the ABS light remains off.
Perform a test drive to ensure the ABS system engages properly during braking.
