2007 Honda bf 225 intermitent buzzer when slowing down or at idle. The alarm never comes on while running. only when coming down trolling to 1000-1500 rpm or at idle. i have replaced sparks, thermostats, battery terminals, air temp sensor, oxigen sensor a while ago, water is cold out of water pump. MIL blinks one short, delay, one long. Need all your help. Thanks
 
It looks like you only have the two-light key switch. I think the procedure for pulling fault codes only works with the 4-light key switch. You may have a separate panel with the overheat and oil pressure indicator lights. If so, then you are getting a Code "1" and a code "10".

Code 1 is usually the HO2 sensor, but a Code 1 is also triggered by a misfiring plug, a failing coil, or fuel pressure out of spec.

Code 10 is the IAT (Intake Air Temperature) sensor. Check the IAT wiring and plug.
