Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

Locate the fuse box; refer to the owner's manual for the ABS fuse location.
Remove the fuse and inspect it for continuity.
If blown, replace it with a new fuse of the same amperage.

3. Check and Replace Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor wiring harness and remove the mounting bolts.
Inspect the sensor for damage; replace if necessary with a new sensor.
Reinstall the new sensor and reconnect the wiring harness.

4. Inspect ABS Control Module

Locate the ABS control module, usually near the brake master cylinder.
Check for corrosion or loose connections in the wiring.
If damage is found, consider replacing the ABS control module.

5. Reconnect Battery and Clear Codes

Reconnect the battery after all repairs are completed.
Use the OBD-II scanner to clear any stored ABS fault codes.
Test drive the vehicle to ensure the ABS light remains off.
