Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the electrical components.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve any stored ABS fault codes.
Document the codes for troubleshooting.
Clear the codes and recheck if the ABS light reappears after a test drive.

3. Inspect ABS Components

ABS Fuse Check: Locate the fuse box, find the ABS fuse, and inspect it for continuity. Replace if blown.
Brake Fluid Level: Check the brake fluid reservoir; refill with the manufacturer-recommended DOT fluid if low.
Wheel Speed Sensors: Locate the wheel speed sensors on each wheel, clean with a soft cloth if dirty, and check for proper connections. Replace if damaged.

4. Check Wiring and Connectors

Inspect the wiring harness leading to the ABS module for any signs of wear, fraying, or corrosion.
Ensure all connectors are securely fastened and free of moisture.
