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 to prevent electrical shock.

2. Scan for Codes

Reconnect the battery and turn on the ignition without starting the engine.
Use an OBD-II scanner to retrieve any stored ABS fault codes.
Document the codes for reference during repairs.

3. Inspect Wheel Speed Sensors

Remove the wheel on the affected corner for access.
Locate the wheel speed sensor, usually mounted near the brake rotor.
Clean the sensor and its connector with electrical cleaner.
Check the wiring for any frays or disconnections.

4. Check ABS Fuse and Relay

Locate the fuse box (usually in the engine compartment or under the dashboard).
Remove the ABS fuse and inspect it for damage; replace if blown.
Test the relay for the ABS system using a multimeter to ensure it operates correctly.

5. Examine Brake Fluid

Open the hood and locate the brake fluid reservoir.
Ensure the fluid is at the proper level; top up with recommended brake fluid (DOT 3 or DOT 4) if necessary.
Check for leaks around brake lines and connections.

6. Test ABS Control Module

If the above steps do not resolve the issue, inspect the ABS control module under the vehicle or in the engine compartment.
Ensure all electrical connections are secure and free from corrosion.
If necessary, use a diagnostic tool to perform an ABS system test to ensure the module communicates properly.

7. Clear Codes and Test Drive

After completing repairs, reconnect the battery and use the OBD-II scanner to clear any fault codes.
Start the engine and perform a test drive to ensure the ABS light does not re-illuminate.
