Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery to avoid electrical shorts.

2. Scan and Clear Codes

Use an OBD-II scanner to read and note any stored error codes.
Clear the codes from the system and take the vehicle for a short test drive to check if the light reappears.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris surrounding the sensors.
Check the wiring harness for signs of damage or loose connections.
If damaged, replace the wheel speed sensor with a new one. Torque to manufacturer's specifications.

4. Check Brake System

Inspect brake fluid levels in the master cylinder reservoir; refill with appropriate brake fluid if low.
Examine brake pads and rotors for wear; replace any worn components.
Ensure the brake lines are free from leaks.

5. Verify Tire Conditions

Check tire pressure using a tire pressure gauge; inflate to the recommended PSI.
Inspect tires for uneven wear or damage; replace if necessary.

6. Test Stability Control Switch

Locate the stability control switch on the dashboard.
Ensure it is functioning properly by toggling the switch on and off while observing the dashboard light.
If defective, replace the switch.
