Solution

1. Preparation

Tools Required: OBD-II scanner, basic hand tools, multimeter, brake cleaner, torque wrench.
Safety Warnings: Disconnect the battery before starting repairs to prevent electrical shorts.

2. Retrieve and Analyze Fault Codes

Connect the OBD-II scanner to the vehicle's port located under the dashboard.
Turn the ignition to the "ON" position without starting the engine.
Retrieve any ABS-related fault codes and note them down for analysis.
Clear the codes, then take the vehicle for a short test drive to see if the ABS light reappears.

3. Inspect ABS Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel on the affected corner (if specific codes indicate a wheel issue).
Clean the ABS sensor with brake cleaner and inspect for damage or misalignment.
Reinstall the wheel and lower the vehicle.

4. Check ABS Module and Wiring

Inspect the ABS module mounted near the master cylinder for any visible damage or corrosion.
Disconnect the wiring harness and check for any loose connections or frayed wires using a multimeter.
Reconnect the wiring and ensure all connections are secure.

5. Verify Brake Fluid Levels

Open the hood and locate the master cylinder reservoir.
Check the brake fluid level, ensuring it is within the recommended range.
If low, top off with the manufacturer-recommended brake fluid type and check for leaks in the brake system.
