Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Check 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.
Inspect the fuse for continuity. Replace with a new fuse of the same amp rating if blown.

3. Inspect and Replace Brake Fluid

Check the brake fluid reservoir for the correct fluid level.
If low, top up with the appropriate brake fluid (DOT 3 or DOT 4 as specified).
If fluid is contaminated, drain and replace the fluid throughout the brake system.

4. Inspect ABS Wheel Speed Sensors

Lift the vehicle safely and remove the wheels as needed to access the sensors.
Visually inspect the ABS wheel speed sensors and harness for damage.
Clean any dirt or debris from the sensors and connectors.
Replace any damaged sensors with new ones.

5. Test and Replace ABS Control Module

Reconnect the battery and use the OBD-II scanner to clear any existing codes.
Perform a test drive to see if the ABS warning light returns.
If it reappears, test the ABS control module's functionality according to the manufacturer’s service manual.
Replace the ABS control module if it fails testing.
