The maintenance required light on your dashboard can be a source of anxiety. Is it a serious problem? Do you need to rush to a mechanic? Understanding what triggers this light and how to address it is key to maintaining your vehicle. This article will delve into the functionality of the maintenance required light and address the common question: Does An Obd2 Scanner Read Maintenance Required?

While the specific process for resetting the maintenance required light varies among car manufacturers and models, the underlying principle remains consistent: it serves as a reminder for routine servicing based on mileage or time intervals. Common services triggered by this light include oil changes, tire rotations, and general inspections.
Ignoring the maintenance required light can lead to performance issues, decreased fuel efficiency, and potentially more serious problems down the road. Addressing it promptly ensures your vehicle remains in optimal condition.
How the Maintenance Required Light Works
The maintenance required light is typically programmed to illuminate after a specific mileage interval, often every 5,000 miles. However, some newer vehicles use algorithms that factor in driving conditions and other data to determine when maintenance is due. This light is not indicative of a specific problem but rather a general reminder for upkeep. Think of it as your car’s way of saying, “Time for a check-up!”
Using an OBD2 Scanner to Diagnose the Maintenance Required Light
So, does an OBD2 scanner read maintenance required? The answer is: it depends.
An OBD2 scanner’s primary function is to read diagnostic trouble codes (DTCs) related to the engine and emissions systems. The maintenance required light, however, is often not associated with a specific DTC. It’s more of a reminder system than a fault indicator.
In most cases, a basic OBD2 scanner will not read the maintenance required light or provide information about why it’s illuminated. These scanners focus on identifying active problem codes, not scheduled maintenance reminders.
However, more advanced professional-grade OBD2 scanners often have the capability to read manufacturer-specific codes and access the maintenance reminder system. This allows mechanics (and some advanced DIYers) to diagnose the reason for the light, reset it after service, and sometimes even customize the maintenance schedule. Tools like the ANCEL DS300 fall into this category.
Resetting the Maintenance Required Light
The process for resetting the maintenance required light varies depending on the make and model of your vehicle. Consulting your owner’s manual is the best way to find the specific procedure for your car.
Common methods involve a sequence of key turns and button presses on the dashboard. Some vehicles might require a specific tool or a visit to a service center for reset.
Beyond the OBD2 Scanner: Other Ways to Address the Maintenance Required Light
If you’re unsure about using an OBD2 scanner or prefer a simpler approach, there are other options:
-
Consult Your Owner’s Manual: Your owner’s manual will have detailed instructions on how to reset the maintenance required light for your specific vehicle model.
-
Visit a Mechanic or Service Center: A professional mechanic can quickly diagnose and reset the light, as well as perform any necessary maintenance.
Conclusion
While a basic OBD2 scanner may not read the maintenance required light, it’s a valuable tool for diagnosing other potential car problems. Understanding the function of the maintenance required light and knowing when to seek professional help are crucial aspects of car ownership. Regular maintenance is key to keeping your vehicle running smoothly and preventing costly repairs in the future. If you’re experiencing issues beyond the maintenance required light, an OBD2 scanner can be an invaluable diagnostic tool. For more complex needs, consult a professional mechanic or your vehicle’s owner’s manual.
