How to Reset the Engine Hour counter on the oval Polaris MFD display

[K447]

I did try the Hour reset procedure you described above on my 1999 SLX to no avail.

It would not enter calibration mode...

Apparently MFD 3280307 (1999 SLX, 12-pin Deutsch connector) does not respond to the same button press methods as the other MFD models. I do not know if there is a different method of triggering Calibration or Engine Hour reset modes on this MFD model.

MFD 3280307 has curved graphical fuel and oil level indicator bars.
This 12-pin MFD apparently also used on the 1999 and 2000 Pro 785 and 2000 SLX, but not the Pro 1200.

So somehow I was replacing my battery and tinkering with things in my 04 virage and my hours went from 120.xx to 553.5 not sure how this happen but it's really worrying me

K447 Do you have info on how to fix faded digits?

See this thread;

When resetting the hours do you have to set the RPMs at 1200? How do you accomplish this on the bench?

Tachometer input is not required, per the info in post #1.

Were you able to watch the video for resetting engine hour counter?

Yes I did, I was just confused about the next part. So it's only required if I want to reset the distance?

Tach input is not required for anything, IIRC. Just that IF there is tach input, the display acts a little different.

It has been a few years since I did the research, built the MFD testing/calibration rig and posted the videos. Am I forgetting something?

Distance Reset is a normal MFD function, as outlined on this page of the Polaris instructions.
