Electronic shift issues

Thanks in advance for any and all help! I’ve been creeping on here for a while, and finally bought a used Honda. It runs fine usually, but now I’m having some issues....

I have a 2012 Foreman 500FPE. The shifting is intermittent. Codes 22 and 23 are showing up. I have tested the angle sensor and it appears to be within specs. I have reset the codes when the shift buttons are responsive, and I get the same codes.

Sometime I walk up to the machine, and it shifts fine. Other times I get no response from the shift buttons upon startup, but it is responsive when the key is on with the engine not running. Other times the buttons are not responsive with the engine off and key on. If I pull the curse in the back, it shifts for a moment, then flashes.

So far I have:
1. Checked fuses-all are good. Also, when I get no response from the shifting buttons, pulling fuses resets something, and allows me to shift for a moment. Then it freezes again.
2. Checked the wiring connection from the harness the shift motor. It is clean with no corrosion.
3. Verified that the battery is at full charge.

Not really sure where to go from here, just hoping someone has some insight!

fish, ya trying to break the newbie,s in right. :devil
ya forgot,, a case of bud, an a manual. the case of bud is so ya read the pages correctly.

I was given a manual with the machine, but it hasn’t arrived yet. It’s also for a 2006 model not a 2012. I have been told the transmission/shifting section is nearly identical for each respective manual.

Hopefully the 30 rack of Busch Light in the fridge will be interchangeable with the Bud Light.

Clean thoroughly and dielectric grease every harness connector pair on the bike and you'll probably fix it. Clean and grease the shift switches too. Don't forget to polish and grease the motor and frame grounds... welcome to the forums!

I’m going to pick up some grease this weekend. Sounds like a tedious task, but I’m sure it’s for the better regardless. When you say shift switches, are you referring to the module on the handlebars with the up/down arrows?

Ok, so my manual came today. It’s a 2009 but I’m told for the shifting issues it will work. I also got the dielectric grease. I plan on greasing all connections this weekend, as well as taking the switch apart and lubing it up.
I also noticed today that the machine jerks forward pretty significantly from neutral to forward. Much more than any manual I’ve ever driven. Because the machine is EFI, I don’t believe I can turn down the idle. So I am assume I need to adjust the clutch, which from other threads seems easy enough. Is lurching forward a foot or so typical?
