2002 Foreman Rubicon D1/D2/ESP flashing

looking for some insight or previous posts to troubleshoot my issue.

They ATV is a 2002 rubicon 500 with just under 600 miles on it. i spent the weekend riding and put on about 75 miles without one issue. I came home, unloaded the four wheeler and gave my son a few laps around the yard. I pulled it into the back to wash it down with a hose(not pressure washer). After drying it off i started and noticed a few things.

1- D1/D2/ESP all flash and it will not display the gear position or drive mode. L D N R or gears 1-5.
2- It will move forward but feels as though you are trying to start out in 4th gear as the motor seems very loaded and slow to start moving.
3- Trying to move in reverse and the motor will pop, spit and sputter.

It WAS NOT/HAS not been in any deep water and as i said ran perfect up until i hosed it down. I am wondering if it is possible something got wet during the washing process?

any input would be appreciated.

If there is no pauses in the blink pattern (giving a code) check the fuses and the connectors at the ecm (above tool box).

it probably got some moisture in the electrical system, being a 2002 with only 600 miles it should be like new... you may want to put some dielectric grease on the electrical connections. it does help. i would park it out in the sun to dry out.

Check code

Can you run it through a diagnostics and see what error code you get? That may help narrow things down. Some of the items work off resistance so having water in a connector or part would change the resistance of that item and may throw it into limp mode.

1. Turn ignition to off
2. place tranny in nuetral
3. put on parking brake so the quad does not move.
4. Press both shift buttons (up and down), and hold them in, while turning the key to on. Make sure the N appears for gear position. Release the buttons.
5. wait 5 secs,and then press both the switches again.and hold them in for at least 3 seconds, then release the switches.
The codes should flash if there are any.

To delete an old code, do the above and when the code appears, that you want to delete, press the switches.
