Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Check and Replace Fuses

Locate the fuse box (usually near the driver's side dashboard).
Remove the ABS fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace it if it’s blown with a fuse of the same amperage.

3. Inspect and Clean ABS Wheel Speed Sensors

Raise the front and rear of the vehicle using a jack and secure with jack stands.
Locate the ABS wheel speed sensors mounted on the wheel hubs.
Disconnect the sensor wiring harness.
Remove the sensor from the hub and clean it with brake cleaner to remove any debris.
Reinstall the sensor and connect the wiring harness securely.

4. Test and Repair Wiring

Visually inspect the wiring harness leading to the ABS control module.
Use a multimeter to check for continuity in the wiring.
Repair any damaged wires with electrical tape or replace sections of wire as necessary.

5. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, fill it with the recommended brake fluid type (usually DOT 3 or DOT 4).
If the fluid is contaminated, consider performing a brake fluid flush.

6. Reconnect Battery and Clear Codes

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