Does an OBD2 scanner read maintenance required? This is a common question among car owners. While an OBD2 scanner is a powerful diagnostic tool, its primary function is to detect and report trouble codes related to emissions and powertrain systems. Let’s delve deeper into the capabilities of OBD2 scanners and explore how they can assist with vehicle maintenance.
Understanding OBD2 Scanner Functionality
OBD2 scanners, also known as diagnostic trouble code (DTC) readers, communicate with a vehicle’s onboard computer. They retrieve diagnostic trouble codes (DTCs), which indicate malfunctions within specific systems. These codes help mechanics pinpoint the source of a problem, streamlining the diagnostic process.
Do OBD2 Scanners Detect Maintenance Needs?
While standard OBD2 scanners excel at reading DTCs related to emissions and powertrain components, they generally don’t directly read maintenance reminders like “Maintenance Required” lights. These lights are often triggered by the vehicle’s internal computer based on mileage or time intervals, not necessarily due to a detected fault. obd2 emissions inspection
However, some advanced OBD2 scanners, especially professional-grade models, can access manufacturer-specific codes. These codes might provide more detailed information about the reason behind a “Maintenance Required” light, such as the need for an oil change or other scheduled service.
“Many modern vehicles use proprietary systems that go beyond basic OBD2 functionality,” explains automotive expert, John Miller, ASE Certified Master Technician. “These systems can offer deeper insights into maintenance needs, but require specialized scan tools to access.”
Using an OBD2 Scanner for Indirect Maintenance Insights
Even if your OBD2 scanner doesn’t directly read maintenance reminders, it can still offer valuable insights for preventative maintenance. For instance, detecting codes related to misfires or oxygen sensor issues could indicate the need for a tune-up or other preventative measures. obd2 p0251
How Can I Reset the Maintenance Required Light?
Resetting the “Maintenance Required” light usually involves a specific procedure outlined in your vehicle’s owner’s manual. It often involves a combination of key turns and button presses. Some advanced OBD2 scanners also have the capability to reset these lights.

“Remember, simply resetting the light without addressing the underlying maintenance needs is not a good practice,” warns Sarah Johnson, Lead Technician at Johnson Automotive. “It’s crucial to perform the necessary maintenance to ensure the proper functioning and longevity of your vehicle.” 38 pin to obd2 lead
Choosing the Right OBD2 Scanner for Your Needs
There are numerous OBD2 scanners available on the market, ranging from basic code readers to advanced professional tools. Consider your needs and budget when choosing a scanner. does 2015 chevy equinox have obd2 If you’re looking for more than just basic DTC reading, consider investing in a scanner that can access manufacturer-specific codes and potentially provide more detailed maintenance information.
Conclusion
So, does an OBD2 scanner read maintenance required? While not directly in most cases, an OBD2 scanner is a valuable tool for understanding your vehicle’s health and can offer indirect insights into maintenance needs. Choosing the right scanner can empower you to stay on top of your vehicle’s maintenance and address potential issues before they become major problems.
