If you've recently used your Innova OBD2 scanner and found yourself staring at a bunch of red icons, you might be feeling a bit overwhelmed.

It's natural to worry when you see red lights, especially when it comes to your vehicle's health. However, there's no need to panic. These red icons serve a specific purpose, and in most cases, they don't indicate severe problems with your car.

What Do the Red Icons Mean?

The red icons on your Innova 5610 are part of the emissions monitors. These monitors are essential for ensuring your vehicle meets environmental and performance standards. Each red icon represents a specific emissions monitor that hasn't completed its check. This doesn't necessarily mean there's a major issue with your car; it just means some systems need further evaluation.

Importance of Emissions Monitors

Emissions monitors play a crucial role in maintaining your vehicle's performance and environmental compliance. They check various aspects of your car's exhaust and fuel systems to ensure everything is working correctly.

Keeping these monitors in check is not only important for your car's performance but also for adhering to legal emissions standards.

Common Types of Emissions Monitors

Here are a few common emissions monitors you might see on your Innova scanner:

  • Oxygen Sensors (O2): These sensors monitor the oxygen levels in your exhaust to help maintain the right fuel-to-air ratio.
  • Catalytic Converter Efficiency (CAT): This monitor checks the efficiency of your catalytic converter in reducing harmful emissions.
  • Evaporative Emission Control System (EVAP): This system detects leaks in your vehicle's fuel system.
  • Exhaust Gas Recirculation (EGR): This monitor ensures that your exhaust gases are being recirculated properly to reduce nitrogen oxide emissions.

Why Are the Icons Red?

The red icons indicate that the emissions monitors haven't completed their checks. This is a normal part of the diagnostic process and doesn't automatically mean there's a severe problem with your vehicle. It's similar to a computer running a virus scan: just because the scan isn't finished doesn't mean your computer is infected.

How to Interpret and Address Red Icons

Understanding what each red icon means can help you address any potential issues without unnecessary stress. Here are a few steps you can take:

  • Check Fuel and Ignition Systems: Make sure your vehicle's fuel and ignition systems are functioning properly.
  • Ensure Gas Cap is Tight: A loose gas cap can trigger some emissions monitors.
  • Drive Under Varying Conditions: Driving your vehicle in different conditions can help the monitors reset and complete their checks.


Seeing red icons on your Innova 5610 OBD2 scanner can be alarming, but they are a normal part of the diagnostic process. These icons are there to help you keep your vehicle running smoothly and ensure it meets emissions standards. Regularly using your scanner and addressing any red icons calmly can help maintain your vehicle's health and give you peace of mind.

Remember, red icons don't necessarily mean big problems; they're just part of keeping your car in top shape.
