Code 81

[billymx815]

Yesterday I went to start my sled (it was very cold out) it fired up then stalled right out. I turned the ignition again and it fired right up and seemed to be running great but code 81 was flashing. I rode the machine for about 10 minutes and the code went away. haven't seen it since. Why would this happen? My hand warmers work great. I have the Yamaheater w/boost so why would this happen and why would it have cleared the code on it's own?

Is this information:

Possible Code 81: (Handwarmers disconnected)
There can be a few causes of this. The first 2 are most common.
1) A loose connection. "Tug Test" all connections into the connectors, make sure they are solid.
2) Low Idle/Low Battery Voltage Makes sure WARM idle is 1300-1400 RPM (See owners manual)
3) The Power Control Relay contacts have to "break-in" This will disappear after riding for a while.
4) Normal G-forces from riding. Random & generally rare.
5) AutoWarm mode is used with SLEDSTART remote start. This is normal to protect your ECU. Restart to clear.
6) The unit itself could have failed, we don't see many of these, yet it IS possible. Return for replacement after calling.

Code 81 is a Minor error code on your sled, it indicates a possible problem with your handwarmers.
It has no effect on your sled other than turning your grips off.
Your YamaHeater will default to High Heat mode if this should occur so you still have warm grips.
The code is easily cleared by shutting off your sled & re-starting.
Trickle charge your battery overnight, most times issue will resolve itself.

Thanks a million Crewchief...It had to be the low idle warning at initial start-up because of the extreme cold etc causing it to tall the first attempt.
