Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid electrical hazards.

2. Inspect and Replace ABS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the ABS fuse using a fuse puller.
Inspect the fuse for any signs of damage; if blown, replace it with a new fuse of the same amperage.
Reconnect the battery.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Check the sensor wiring for frays or disconnections.
Clean the sensor and surrounding area to remove any debris.
Reinstall the wheel and lower the vehicle.

4. Address Brake Fluid Level

Open the hood and locate the master cylinder.
Check the brake fluid level; if low, top it up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect for any leaks in the brake lines or around the master cylinder.

5. Reset ABS System

Reconnect the battery if it was disconnected.
Use the OBD-II scanner to clear any stored ABS error codes.
Test drive the vehicle to check if the ABS light remains off.
