Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace ABS Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the ABS fuse based on the diagram on the fuse box cover.
Remove the fuse using a fuse puller and inspect it for continuity.
- If blown: Replace it with a new fuse of the same amperage.
- If not blown: Reinstall the fuse.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and support it with jack stands.
Remove the wheels to access the wheel speed sensors.
Clean the sensors and surrounding areas using brake cleaner.
Reconnect any disconnected wiring and ensure the sensors are securely mounted.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
- If low: Add the recommended brake fluid type (DOT 3 or DOT 4).

5. Test ABS Module

Reconnect the battery terminal.
Use the OBD-II scanner to clear any existing error codes.
Start the vehicle and check if the ABS light remains illuminated.
If the light turns off, conduct a test drive to ensure the ABS system is functioning correctly.
