Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical shorts.

2. Retrieve Fault Codes

Connect an OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and note any ABS-related fault codes for further analysis.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Clean any dirt or debris from the sensors and connectors.
Check for damaged wiring or loose connections. Repair or replace as necessary.

4. Examine ABS Control Module

Locate the ABS control module, typically found near the master cylinder.
Inspect for corrosion or loose connections on the module.
If codes indicate a module failure, consider replacing the ABS control module.

5. Check Brake Fluid Level

Open the master cylinder reservoir cap.
Verify the brake fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4).
Inspect for any leaks in the brake lines.

6. Replace Faulty Components

If any components (sensors, fuses, or the ABS module) were found faulty, replace them with OEM or quality aftermarket parts.
Reassemble any disassembled components securely.

7. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and check if the ABS light remains illuminated.
If the light is off, conduct a test drive to ensure the ABS system is functioning properly.
