Did you unplug the EXUP servo motor?

That's the cause.
The missing servo motor is causing the warning light.

You can:

1) Mount and plug the servo motor back in (without the control cables in place).
2) Buy one of the servo eliminators on the market and plug that in.
3) Try the modification that uses a small resistor to do what the servo eliminator does.
4) Run it as-is.

I've check and I have a servo eliminator, but still sometimes the check engine get on.
It might be that the servo device isn't working properly?
There is nothing written on it so I don't know what is his brand, should I buy another one and change it?
If yes what brand is the most recommended?


Thanks

Solution (3) is a sticky right here on this site: http://wr250rforum.forumotion.com/t627-cheapest-diy-servo-bypass

It's simple, cheap, and it works; I used a 10k, 1/4W resistor.

Hey,
Finally I have checked the codes.
Those are the codes:
17
18
21
30
33
42

Also my battery shows 11.2 is that OK?
Thanks

11.2v is totaltally discharged, so no.
But it should recover fine when fully charged.

Hi, perhaps this can help you:
