Honda Maintenance Minder System

As the automakers compete to bring the best to the market, Honda isn’t left behind. Honda decided to research and come up with a solution for a digital service reminder instead of a maintenance schedule in the owner's manual. Additionally, there is no need for the next service record on the record papers. Honda Maintenance Minder System uses an onboard computer to monitor the engine operating conditions. Conditions monitored include the temperature, speed, time, and vehicle use to determine the actual time for regular maintenance.

That aside, the cars are programmed with different codes based on the service type needed. The codes vary depending on the honda vehicle model and the trim level. For instance, when the honda civic is serviced, it starts to show engine oil life in percentage. At the start, the oil life percentage is at 100%. But as the service mileage nears, the percentage decreases. Once the oil life gets to 15%, the maintenance minder light will illuminate. And when it gets to zero, it will signal you the oil life is over. Below are examples of the warnings you will see once your engine oil life reaches a critical level:
HONDA ENGINE OIL LIFE (%) DASHBOARD MESSAGE ACTION TO TAKE
