Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on the electrical components.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wire brush, brake cleaner.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position (do not start the engine).
Retrieve any stored ABS-related error codes and note them for further analysis.

3. Inspect and Clean Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris using a wire brush and brake cleaner.
Check the sensor connectors for corrosion; clean if necessary.
Reconnect the sensors and ensure they are securely fastened.

4. Check ABS Control Module

Locate the ABS control module (typically near the master cylinder).
Inspect for any signs of corrosion, loose connections, or physical damage.
If damaged, replace the ABS control module according to the manufacturer's instructions.

5. Verify Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if it is low, top up with the recommended brake fluid type (DOT 4).
If the fluid appears dirty or contaminated, consider flushing the brake system.

6. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and check if the ABS light is still illuminated.
Perform a test drive to ensure that the ABS system is functioning properly.
