Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor and connector.
Check the wiring for frays or disconnections.
If a sensor is damaged, replace it with a new one.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, top off with the correct type of brake fluid (DOT 4).
If the fluid level is consistently low, check for leaks in the brake lines or calipers.

4. Examine Stability Control Module

Use the OBD-II scanner to clear any fault codes related to the stability control system.
If codes reappear, inspect the wiring and connectors for the stability control module for damage.
Replace the module if it is determined to be faulty.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and observe if the stability control light has turned off.
Perform a test drive to ensure stability functions are working correctly.
