Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the ignition is off.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Retrieve Diagnostic Codes
  • Connect the OBD-II scanner to the vehicle’s diagnostic port.
  • Turn the ignition to the "ON" position without starting the engine.
  • Record any trouble codes related to the VSC system for further analysis.
3. Check Brake Fluid Level
  • Locate the brake fluid reservoir under the hood.
  • Inspect the fluid level; it should be between the "MIN" and "MAX" lines.
  • If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
4. Inspect Wheel Speed Sensors
  • Raise the vehicle and secure it on jack stands.
  • Visually inspect the wheel speed sensors located at each wheel hub.
  • Check for any signs of damage or corrosion on the wiring and connectors.
  • Clean any debris or dirt from the sensors.
5. Test VSC System Fuse
  • Locate the fuse box and identify the fuse related to the VSC system.
  • Remove the fuse and check for continuity using a multimeter.
  • Replace the fuse if it is blown, ensuring to use the correct amperage.
6. Check ABS Module Connections
  • Inspect the ABS module connections for corrosion or loose wiring.
  • Ensure all connectors are seated securely.
  • If necessary, remove and clean the connections before reattaching.
7. Clear Codes and Test Drive
  • After addressing any issues, use the OBD-II scanner to clear the trouble codes.
  • Reconnect the negative battery terminal.
  • Start the vehicle and take it for a test drive to check if the VSC light remains off.
