Yamaha fault codes

Hi,

Yesterday a little sign of an engine started to flash on the rev counter gauge, it was flashing twice, then 8 times in a row, then twice again and repeat.

I have had a look in the manual but cannot see this mentioned, engine seems to be running fine except idling around 300 rpm more than normal. Does anyone know what this means? Engine is a Yamaha 200 hpdi.

Cheers

Fault code

28 in -gear start. May have been started or cranked in gear , or not quite in neutral.
Once isolated fault code will disappear on tacho....but remain on system.
Can only be cleared with laptop YDS system in history. Not a problem ,not a must as would be done in service.
For info 13 = coil input
15 = water temp sensor
18 = tps
19 = battery + voltage
23 = air intake temp
29 = air intake pressure
33-44 computer processing info
( 33) = ign timing corrected ( cold eng )
( 37) = intake pass air leak
(44) = stop switch control operating

Hope of some interest !

Hi, thanks, that is really helpful and I am going to make a note of those other codes just in case.

In gear start would make sense as the engine was a bugger to get in an out of gear, I have been told I need to adjust the gear shift cable. I assume I do this from the engine end.

Cheers
