Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool down if it has been driven recently.

2. Inspect and Replace ABS Fuse

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

3. Check and Clean Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate the ABS wheel speed sensors on each wheel hub.
Disconnect the wiring harness from each sensor.
Clean the sensor and mounting area with brake cleaner to remove dirt and debris.
Reconnect the wiring harness securely.

4. Inspect ABS Control Module and Wiring

Trace the wiring harness from the ABS control module to each wheel speed sensor.
Look for any signs of damage, such as fraying or corrosion.
Repair or replace damaged wiring as necessary.

5. Refill Brake Fluid and Bleed System

Check the brake fluid reservoir and top it off with the manufacturer's recommended brake fluid.
If any leaks were found earlier, address them and bleed the brake system to ensure no air is present.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light is still illuminated.
Conduct a test drive to confirm that the ABS functions properly and the light remains off.
