Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
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 sensors.
Check the wiring harness for fraying or disconnection.
If damaged, replace the sensors with new ones.

3. Check Stability Control Module

Locate the stability control module, usually near the brake booster or under the dash.
Inspect the module for physical damage or corrosion.
Ensure all connectors are properly seated and free from dirt.
If necessary, reprogram or replace the module.

4. Tire Inspection

Check each tire for proper inflation and tread depth.
Inflate tires to the recommended pressure if low.
Replace any tires that are excessively worn or damaged.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Turn on the ignition and check if the stability control light remains illuminated.
Perform a test drive to ensure the system operates correctly and the light does not reappear.
