Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the wheel to access the sensor if necessary.
Visually inspect the sensors for dirt, damage, or disconnection.
Clean any debris from the sensor area with a soft cloth.
Reconnect any loose connectors and ensure a secure fit.

3. Check Brake System

Inspect brake fluid reservoir; top off with the recommended fluid if low.
Examine brake lines for leaks or damage.
If any components are damaged, replace them as needed.

4. Verify ABS Functionality

Turn the ignition key to the "On" position without starting the engine.
Listen for the ABS pump operation and check for any warning lights.
If there are warning lights, further diagnostics of the ABS module may be required.
