Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, appropriate socket set, and safety gloves.
Ensure the vehicle is parked on a flat, stable surface and the ignition is off.

2. Connect OBD-II Scanner

Locate the OBD-II port, typically under the dashboard near the steering column.
Plug in the OBD-II scanner and turn the vehicle's ignition to the "ON" position without starting the engine.

3. Scan for ABS Module Codes

Navigate to the ABS section on the scanner.
Select the option to read DTCs.
Document any codes that are found for further analysis.

4. Analyze DTCs

Cross-reference the DTCs with a repair manual or online database to interpret the errors.
If codes indicate faulty components (e.g., wheel speed sensors), proceed to inspect those components.

5. Inspect ABS Module Connections

Disconnect the battery to ensure safety before working on electrical components.
Locate the ABS module and inspect its electrical connectors for signs of corrosion or loose connections.
Use a multimeter to check for continuity in wiring leading to the ABS module.

6. Repair or Replace Faulty Components

If any faulty components are identified, replace them with OEM parts.
Reconnect the wiring and connectors securely.

7. Clear Codes and Test Drive

Use the OBD-II scanner to clear the DTCs from the ABS module.
Test drive the vehicle to ensure the ABS system is functioning correctly and the warning light does not reappear.
