Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal.

2. Check and Replace ABS Fuse

Locate the fuse box (usually under the dashboard or hood).
Remove the ABS fuse and inspect it. Replace it if blown (consult the owner's manual for the correct fuse specification).

3. Inspect and Clean Wheel Speed Sensors

Lift the vehicle securely using jack stands.
Locate the wheel speed sensors (usually mounted near the brake caliper).
Disconnect the sensor connector and clean the sensor tip with brake cleaner.
Check the sensor wiring for any signs of wear or damage; repair as necessary.
Reconnect the sensor and ensure it is securely mounted.

4. Brake Fluid Inspection and Replacement

Check the brake fluid reservoir for the correct fluid level.
If low, add brake fluid compatible with the vehicle (DOT 3 or DOT 4, as specified in the manual).
If the fluid is contaminated, perform a brake fluid flush and replace it with fresh fluid.

5. Test Drive and Scan for Codes

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light remains on.
If the light is off, take the vehicle for a test drive to ensure the ABS operates correctly.
Re-scan for error codes; clear any existing codes if the issue is resolved.
