Solution
1. Preparation
  • Gather tools and ensure a clean workspace.
  • Disconnect the vehicle’s battery to prevent electrical shorts or shocks.
2. Scan and Clear Error Codes
  • Use an OBD-II scanner to read and record any stored error codes.
  • Clear the error codes and note if they return upon restarting the vehicle.
3. Inspect Battery and Charging System
  • Check battery voltage with a multimeter; it should read around 12.6 volts when fully charged.
  • Inspect battery terminals for corrosion and ensure they are securely connected.
  • Test the alternator output while the engine is running; it should be between 13.7 to 14.7 volts.
4. Check Brake System
  • Inspect brake fluid level in the reservoir; refill with the proper DOT fluid if low.
  • Examine brake lines and pads for wear or leaks.
  • If the brake warning light persists, replace any faulty brake components.
5. Inspect ABS System
  • Locate the ABS module and inspect wiring and connectors for damage.
  • Check each wheel for the presence of the ABS sensor and clean or replace as necessary.
6. Examine Airbag System
  • Remove the airbag module if necessary to inspect connections and wiring.
  • Ensure all connectors are secure and free of corrosion.
  • Replace any faulty airbag components as indicated by error codes.
7. Check Traction Control System
  • Inspect wheel speed sensors at each wheel for damage or disconnections.
  • Clean any debris or rust from sensor mounting points.
  • Replace any malfunctioning sensors.
