Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts or shocks.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Inspect and Replace ABS Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse; if it's blown, replace it with a new fuse of the same amperage.

3. Clean or Replace Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector and remove the sensor.
Clean the sensor and mounting area with brake cleaner, or replace it if damaged.
Reinstall the sensor and reconnect the electrical connector.

4. Inspect and Repair ABS Module

Locate the ABS module, usually near the master cylinder.
Check for any fluid leaks around the module.
If leaks are found, replace the ABS module according to the manufacturer's specifications.
Reconnect all electrical connectors securely.

5. Check Brake Fluid Level

Open the master cylinder reservoir cap.
Inspect the brake fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4).
Check for any leaks in brake lines or connections.

6. Reconnect Battery and Test Drive

Reconnect the battery terminals securely.
Start the vehicle and check if the ABS light is still illuminated.
Test drive the vehicle in a safe area to ensure the ABS engages properly.
