Solution

1. Preparation

Gather necessary tools and components.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the battery for safety.

2. Check ABS Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the ABS fuse and inspect it for continuity using a multimeter.
If blown, replace with a new fuse of the same amperage.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor wiring harness and inspect for corrosion or damage.
Clean the sensor and surrounding area with brake cleaner.
Reconnect the sensor and replace the wheel.

4. Inspect ABS Control Module Wiring

Locate the ABS control module under the hood.
Visually inspect the wiring harness for frays, cracks, or loose connections.
Repair any damaged wiring and ensure all connectors are firmly attached.

5. Check Brake Fluid Level

Open the master cylinder reservoir cap.
Inspect the brake fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).

6. Reconnect Battery and Test Drive

Reconnect the battery terminals.
Start the vehicle and check if the ABS light is still illuminated.
Perform a test drive to ensure the ABS system functions correctly.
