I have a 2006 Honda Civic LX 4-door sedan. Rather than a fixed maintenance schedule, this car has a "maintenance minder" display on the dash which counts down the remaining "oil life" (based, I believe, on a combination of time, miles driven, and engine revs). When the oil life reaches 10%, the minder displays a code indicating which maintenance items are needed (oil change, fuel filter replacement, spark plugs, etc).
Right now, the oil life indicator is at 40%, so no codes are displayed. But I have a long trip coming up, and I'd like to consider having the next maintenance done early.
How can I find out what items will be needed at the next service? I don't have a code reader, but an answer involving one would still be useful, as it means my mechanic will be able to tell me.
