Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect Brake Fluid

Locate the brake fluid reservoir.
Check the fluid level; if low, top off with the manufacturer's recommended brake fluid type.
Inspect for leaks around the reservoir and brake lines, repairing as necessary.

3. Inspect ABS Wheel Speed Sensors

Identify the location of the wheel speed sensors at each wheel hub.
Remove the wheel to access the sensor if needed.
Clean the sensor using a soft cloth and inspect the wiring for any fraying or disconnections.
Reconnect any loose connections and replace any damaged sensors.

4. Check ABS Control Module

Locate the ABS control module, usually found near the master cylinder.
Inspect the module for corrosion or damage on connectors and wiring.
Clean any corrosion with electrical cleaner and ensure all connections are secure.

5. Reconnect Battery and Reset System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes.
Turn the ignition on and check if the ABS light remains illuminated.
