Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety during repairs.
2. Inspect Wheel Speed Sensors
  • Remove the wheel covers or wheels if necessary.
  • Clean the wheel speed sensors and their connectors using electrical contact cleaner.
  • Ensure sensors are properly aligned and securely mounted.
3. Check Brake Fluid Level
  • Open the hood and locate the brake fluid reservoir.
  • Inspect the fluid level; if low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
  • Check for any visible leaks in the brake lines or around the master cylinder.
4. Inspect ABS Control Module Connections
  • Locate the ABS control module, typically found near the brake master cylinder.
  • Disconnect the electrical connector and inspect for corrosion or damaged pins.
  • Clean the connections and reconnect securely.
5. Test Stability Control Switch
  • Locate the stability control switch, usually near the driver's side dashboard.
  • Press the switch to see if the stability control system can be reset.
  • If the switch is faulty, replace it with a new part.
6. Reconnect Battery and Clear Codes
  • Reconnect the negative battery terminal.
  • Use the OBD-II scanner to clear any stored DTCs.
  • Conduct a test drive to ensure the stability control light does not re-illuminate.
