Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensor area using a soft brush.
Check the wiring harness and connectors for signs of wear or damage.
If a sensor is faulty, remove it using a socket set and replace with a new one.

3. Check Stability Control Module

Locate the stability control module, usually found under the dashboard or near the brake control unit.
Inspect the wiring harness for any signs of corrosion or loose connections.
If necessary, disconnect the module and perform a continuity check with a multimeter.
Replace the module if it is found to be defective.

4. Inspect Brake System

Check the brake fluid level and top up if low using the manufacturer's recommended brake fluid type.
Inspect brake lines and fittings for leaks or damage.
If any leaks are found, replace the affected components.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and observe if the stability control light turns off.
Perform a test drive to check for proper stability control operation.
