Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, multimeter, socket set, safety goggles, and gloves.
Disconnect the battery to ensure safety while working on electrical systems.

2. Inspect ABS Sensors

Remove the wheel where the ABS light is indicated (if specific wheel is suspected).
Using a socket set, unbolt and remove the wheel speed sensor.
Clean the sensor and the area around it to remove any dirt or debris.
Reinstall the sensor and ensure it is securely attached.

3. Check ABS Fuse

Locate the fuse box (refer to the owner's manual for exact location).
Remove the ABS fuse and inspect it for continuity using a multimeter.
If the fuse is blown, replace it with a new fuse of the same amp rating.

4. Inspect Brake Fluid

Open the master cylinder reservoir cap.
Check the brake fluid level; if low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
Inspect the fluid for contamination; if dirty, consider a brake fluid flush.

5. Reconnect Battery and Clear Codes

Reconnect the battery.
Use the OBD-II scanner to clear any stored ABS trouble codes.
Start the vehicle and check if the ABS light remains off.
