Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and brake cleaner.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve any ABS fault codes and note them down.
Clear the codes using the scanner and check if the warning light returns after a short drive.

3. Inspect ABS Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Disconnect the wiring harness from the sensors.
Remove the sensors by unscrewing them from their mounts.
Clean the sensor tips with brake cleaner and inspect for damage; replace if necessary.

4. Check ABS Control Module Connections

Locate the ABS control module, typically found near the master cylinder.
Disconnect the wiring harness and inspect for corrosion or loose connections.
Clean the terminals with electrical contact cleaner and reconnect securely.

5. Inspect Brake Fluid and Wiring

Check the brake fluid reservoir; top it off with the recommended fluid if low.
Inspect the ABS wiring harness for frays or breaks; repair or replace damaged wiring as necessary.

6. Reassemble and Test

Reinstall the ABS wheel speed sensors and reconnect all wiring harnesses.
Lower the vehicle and start the engine.
Conduct a test drive to verify that the ABS warning light remains off and the braking system functions properly.
