Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Reset Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any stored error codes.
If codes are related to temporary issues, reset the codes and check if the stability control light reappears after a test drive.

3. Check Wheel Speed Sensors

Locate each wheel speed sensor (usually near the brake assembly).
Clean any dirt or debris from the sensor area.
Test each sensor's resistance using a multimeter; replace any sensors that are out of specification.

4. Inspect ABS Module and Wiring

Visually inspect the ABS module and all related wiring harnesses for any signs of damage or corrosion.
Ensure all connectors are secure and free from moisture.
If necessary, replace damaged wiring or connectors.

5. Tire and Alignment Check

Measure tire pressure and ensure all tires are inflated to the manufacturer’s recommended levels.
Inspect tire tread for uneven wear patterns that might indicate alignment issues.
If alignment is off, take the vehicle to a professional alignment service.

6. Reconnect Battery and Test

Reconnect the battery and ensure all connections are tight.
Start the vehicle and check if the stability control light remains off.
Conduct a test drive to confirm the stability control system is functioning properly.
