Even with the Maintenance Minder all anyone has to do reset it without doing that maintenance. Example I had service last week at Honda Dealer Service.
The service manager called me on the phone and asked did I want to have the Transmission Fluid Replaced. The Maintenance Minder system was showing the code for it. But we many times go over by as much as 2K before getting service so it's saying past due. The tire shop rotates the tires so dealer never does it. Service manager pulled up service history on computer and said I had Trans Service done at some mileage interval was not time to get done again.
But unless you can find a service history from a dealer or records from some other source it's a guessing game.

Unless the system is not functioning, you will only get service notifications when the MM thinks it is time for a particular service interval which are mileage based. Otherwise your screen will only show your total mileage, trip miles, outdoor temp, etc. It is likely the TB code (if it is 4, I dont know without looking at my manual) did in fact fire back around 105k miles, and the owner or dealer reset it. We don't know if the service was actually done, the MM relies on the human input to reset it.

#4 is replace spark plugs & check adjust valves also. Don't forget water pump should be replaced if Timing Belt was done.
