Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace ABS Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Remove the ABS fuse using a fuse puller.
Inspect the fuse visually; if it's blown, replace it with a new fuse of the same amperage.

3. Inspect and Clean ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel assembly.
Remove any dirt or debris around the sensors using a clean cloth.
Check the sensors for physical damage; replace if damaged.
Reconnect any disconnected or loose connectors.

4. Inspect Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
If the fluid is contaminated, consider a brake fluid flush.

5. Test and Replace ABS Module (if needed)

After ensuring all connections and components are in order, reconnect the battery terminal.
Reconnect the OBD-II scanner to clear any existing fault codes.
Test drive the vehicle to see if the ABS light remains off.
If the light remains on, further diagnostic testing of the ABS module may be required, and replacement might be necessary.
