Maintenance Minder Systems
Starting in 2007, all Honda and Acura models came equipped with a maintenance minder system. This system calculates the life of the engine oil, transmission fluid, air and micron filters, coolant, spark plugs, timing belt (if equipped), and rear differential fluid. Because the computer is calculating the life span of the different items, a scheduled maintenance list based on mileage is no longer used.
The computer determines the life of each item based upon the driving conditions of the vehicle. If the engine runs at higher temperatures and rpm, or at low temperatures during short trips, the oil life will deplete faster than an engine running under normal conditions. It will indicate a percentage of oil life on the vehicles display.
This system is unique in that it has the ability to move up or delay other services so when it’s time to have an oil change it will tell you the other services are needed at the same time to keep the service visits to a minimum.
A percentage will show up on the display starting off at 100% and diminishing as the vehicle is driven. Once the percentage gets to 15% a wrench on the dash is illuminated letting the owner know that service is due soon. At 5% the service is due now and at 0% the service is overdue. The system will count in negative numbers the past due mileage.
The first code is either A or B, A requires an oil change only and B requires an oil and filter change. The second code (Sub Item) will contain letters 1-6:
- Tire rotation
- Air Filter and Micron filter (Cabin Filter) replacement, and check the drive belt
- Transmission fluid, and transfer fluid (if equipped)
- Spark plug replacement, timing belt replacement (if equipped), inspect water pump and valve clearance
- Engine coolant replacement
- Differential fluid replacement (where applicable)
Once the vehicle is serviced, it’s important for the technician to reset the maintenance minder system so it can start the calculation process all over again.
