Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools, and a brake fluid tester.
Ensure the vehicle is on a level surface, parked securely, and the engine is off.
Disconnect the battery negative terminal to ensure safety.

2. ABS Fuse and Relay Inspection

Locate the fuse box and remove the cover.
Using a multimeter, test the ABS fuse for continuity. Replace if blown.
Check the ABS relay function by swapping with a similar relay (if applicable) or testing it with a multimeter.

3. Wheel Speed Sensor Inspection

Raise the vehicle securely using jack stands.
Locate each wheel speed sensor (usually near the brake rotor).
Clean the sensor area to remove dirt or debris.
Check the wiring and connector for signs of wear or corrosion. Replace the sensor if damaged.

4. Brake Fluid Check

Remove the brake fluid reservoir cap and check fluid levels.
Use a brake fluid tester to verify fluid quality; replace the fluid if contaminated or below recommended levels.

5. ABS Module and Wiring Inspection

Examine the ABS control module for physical damage or water intrusion.
Inspect the wiring harness connected to the ABS module for frays or loose connections.
Repair or replace damaged wiring or connectors as necessary.

6. Resetting the ABS Light

Reconnect the battery terminal.
Use the OBD-II scanner to clear any ABS fault codes.
Start the vehicle and check if the ABS light remains off.
