2009 Grizzly 550 EPS FI ER-1 CODE

My new 2009 EPS 550 stalled and then would turn over but would not stay running. The display read ER-1 I dis-connected the battery and re-connected then it started right up with no error code. Everything seams fine, does anyone know what the ER-1 code means?

Er-1, ECU internal malfuntion (output signal error). No signal recieved from ECU. Sounds like you did the right thing to correct the problem. Make sure battery is fully charged, connections are tight, and you keep it on a "Battery Tender" when stored. If it keeps happening I would have the dealer check it out. Good Luck.

Thanks for the reply, The ATV is only 1-month old and the battery bolt on the positive does seam to be stripped. The aluminum nut doesn't grab the bolt anymore. Can I use stainless steel?

That is a special type of contained nut. I would swing by a battery shop and pick up one. They'll probably just give you one. You would have problems keeping a standard type nut from turning while you tighten the screw.

How old is your battery. Mine had the same problem on Sunday. Mine was also throwing code 46....means low power output. Got a Deka battery coming this week to solve the problem.
