Solution

1. Preparation

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

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any error codes related to the stability control system.
Clear the fault codes and turn the ignition on to check if the light reappears.

3. Inspect Wheel Speed Sensors

Remove the wheel covering the sensor.
Disconnect the sensor connector and inspect for corrosion or damage.
Clean the sensor and the mounting area with brake cleaner.
Reconnect the sensor and reinstall the wheel.

4. Brake Fluid Check

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the minimum and maximum lines.
If the fluid is low, top it up with the recommended brake fluid type (usually DOT 4).

5. ABS Module Testing

Using a multimeter, test the voltage and ground connections at the ABS module.
If necessary, replace the ABS module if it fails to communicate with the OBD-II scanner.

6. Wiring Inspection

Visually inspect the wiring harness connected to the stability control system for frays or breaks.
Repair or replace any damaged wiring found during the inspection.

7. Wheel Alignment and Tire Check

Take the vehicle to a professional for a wheel alignment if necessary.
Inspect tires for uneven wear, which can affect stability control, and replace if needed.
