my Ram 1500 DT (2019-Present) has a dashboard warning light on what does it mean

Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, multimeter, tire pressure gauge.
• Ensure the vehicle is parked on a flat surface with the engine off.
• Disconnect the battery to ensure safety during inspection.

2. Address Error Codes

• Plug in the OBD-II scanner and retrieve the diagnostic trouble codes (DTCs).
• Note the codes and consult the repair manual for specific troubleshooting based on the codes.

3. Inspect & Repair Components

• Electrical Inspection:
  • Check battery terminals for corrosion and clean them if necessary.
  • Use a multimeter to test battery voltage (should be around 12.6 volts).
• Fluid Levels:
  • If fluid levels are low, top them up with the appropriate fluids (engine oil, coolant).
• Brake System:
  • Inspect brake pads and rotors for wear. Replace if needed.
  • Check brake fluid level; if low, top up with the correct fluid.
• Tire Pressure:
  • Use a tire pressure gauge to check all tires. Inflate tires to the manufacturer’s specifications.

4. Clear Codes and Test Drive

• After addressing the issues, use the OBD-II scanner to clear the error codes.
• Start the engine and monitor for any warning lights.
• Conduct a test drive to ensure the vehicle operates normally without warning lights.
