Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat, stable surface and secure it with wheel chocks.
Disconnect the battery negative terminal to prevent electrical shorts.

2. Inspect the ABS Fuse

Locate the fuse box (refer to the owner’s manual for exact location).
Remove the cover and check the ABS fuse.
If blown, replace it with a new fuse of the same amperage.

3. Check Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor's electrical connector.
Inspect the sensor for dirt or damage; clean it if necessary or replace if defective.

4. Inspect Wiring and Connectors

Trace the wiring from the ABS module to the wheel speed sensors.
Look for any signs of wear, fraying, or corrosion.
Repair or replace any damaged sections of wiring or connectors.

5. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level.
If low, top it off with the recommended brake fluid type (e.g., DOT 3 or DOT 4).
If the fluid is contaminated, flush the brake system and replace with fresh fluid.

6. Reset the ABS System

Reconnect the battery terminal.
Use the OBD-II scanner to clear any ABS-related trouble codes.
Perform a test drive to confirm the ABS light is no longer illuminated.
