Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Make sure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the battery to reset the system (optional, but recommended).
2. Addressing Diagnostic Trouble Codes (DTCs)
  • Connect the OBD-II scanner and retrieve any stored DTCs.
  • Note the codes and refer to the repair manual for specific troubleshooting related to each code.
  • Clear the codes using the OBD-II scanner to see which, if any, reappear after a test drive.
3. Fluid and Battery Check
  • Fluid Levels: Top off any low fluids (engine oil, brake fluid, coolant) as needed. Use the manufacturer's recommended fluids.
  • Battery Inspection: Check battery terminals for corrosion and ensure a tight connection. Clean terminals if necessary.
4. Brake System Inspection
  • Inspect brake pads for wear and replace if necessary.
  • Check the brake fluid level in the reservoir; if low, top it off with the recommended fluid.
  • If the brake warning light remains on after addressing fluid levels, a brake system inspection may be required.
5. Tire Pressure Assessment
  • Use a tire pressure gauge to check each tire's pressure.
  • Inflate tires to the recommended pressure levels indicated on the driver's door jamb.
6. Final Steps
  • Reconnect the battery if it was disconnected.
  • Start the vehicle and observe if the warning lights stay off after the engine is running.
