Engine light on help with error codes

HI all! I noticed my bike's engine light was on while riding. Runs fine. I did the diagnosis thing  by pressing 1 and reset buttons on the console. I found that I had an error code 30. I think it is a tilt sensor thing. the memory said I have 2 errors.  I tried to  reset the code. I cannot erase the error codes. I can't see the other code. I there an algorithm I can follow ? Should I run the bike again to see if they re post to the bikes memory?
Any help will be greatly appreciated!

You need to flip the killswitch to erase the codes.

Ok so my bike has no exup servo. It has an aftermarket fmf exhaust and a megabomb on the header. I have been riding her for about 500 miles since I got her and had no engine light on or error code 17 . When I flip the kill switch the error code does not erase. I am now looking for where the servo used to be so maybe I can check if there was an electric bypass or maybe a plug that does the same. Need help finding out where the plug is or was.

Awesome! thanks! Now I need to figure out why the bike ran so long without cel coming on . There is no plug attached to the servo plug, like an exup eliminator, Just a bare yellow plug. I don't mind buying an exup eliminator plug but would like to make darn sure that it will surely do the trick. The 17 error code indicates an open circuit or a short. How would I go about checking for an open or short circuit. I have an ohm meter but don't know how to check the yellow plug. Any help greatly appreciated!!!

This thread describes how you can eliminate the EXUP CEL with just one resistor connected to the plug: https://wr250rforum.forumotion.com/t627-cheapest-diy-servo-bypass
