Hi !
I bought a 2006 Honda Aquatrax that was parked for several years. It only has 32 hours when I bought it.
It runs smooth for a while, and then it's begins to fail.
I replace oil and spark plugs with 4 brand new IMR9D-9H, but it keeps failing.
I jumped dianostic terminal ( green and brown cables ) and press SET + MODE for 5 seconds and it starts beeping.
The Service manual I've download says somethuing about long beeps and short beeps, but it makes only short beeps, folowed by a long pause.
This are the codes it beeps:

The "---" is a long pause...
I see a pattern, the 1 2 3 and 4 beeps are numbers below 6, then 11/12/13 twho times, and then a closing 7/8...

Does anybody understands this fault codes?
