Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to avoid electrical shorts.

2. Inspect ABS Sensors

Remove the wheel for access to the ABS sensor.
Check the wiring and connector for frays or corrosion.
Clean or replace the ABS sensor if damaged.
Reinstall the wheel and torque lug nuts to manufacturer specifications.

3. Check ABS Module

Locate the ABS module, typically near the master cylinder.
Inspect the wiring harness for loose connections or damage.
If applicable, reset the ABS module using the scanner and clear any stored codes.

4. Brake Fluid Check

Remove the brake fluid reservoir cap.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the appropriate brake fluid type as specified in the owner’s manual.

5. Final Check and Reconnect Battery

Reconnect the battery terminals.
Start the vehicle and observe if the ABS light goes off.
If the light persists, consider further diagnostics or professional assistance.
