Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt and debris using a soft brush or cloth.
Check the sensor connectors for corrosion and clean with electrical contact cleaner if needed.
Reconnect the sensors securely.

3. Check Brake Fluid and ABS Module

Inspect the brake fluid reservoir; top up with the recommended brake fluid if low.
If any leaks are detected in the brake lines, replace the faulty components promptly.
Use the OBD-II scanner to check for ABS module fault codes, clear any codes if necessary.

4. Test Drive

Reconnect the battery and start the vehicle.
Conduct a test drive in a safe area to see if the stability control light remains off and the vehicle handles normally.
