VSS Error - Throttle Run Away!

[Rando]

This morning, when I went to start my Spyder, it fired up and immediately died. There was a scrolling VSS error message. I turned the key off, waited a few minutes and did a restart. The VSS error message was gone but it was idling higher than normal. When I checked to see if the throttle was stuck, it started revving higher when I tried to back off the throttle! I quickly hit the kill switch as it was continuing to rev even higher.

I shut it off, waited about 5 minutes and after a restart everything was normal and I had an uneventful ryde to work.

Very strange to say the least!

I had that happen when I put an aftermarket Ebay HID kit in that didn't get along with the bike well. Do you have any aftermarket electrical mods that could be pulling alot of power??? Also I suspect a week battery or connection can cause this.

Same thing here. I added a kit from HIDsquad for the fog lights and when the battery was a little low, I got an error message and the rpms climbed up on restart. Now I just keep the fog lights off till over idle on start-up.

SE5 or SM5?

Perhaps a battery tender would be a good investment for you. I keep mine plugged in overnight a few times a week--- and all winter long.

Happened to Roaddog a while back. Throttle position sensor was no good, and the throttle bodies had to be synced......

Yepper :agree:

Full battery works wonders...

My 08 SM has some peculiar quirks when the battery charge is down some. I use a Deltran battery tender over night about every 10 days. This seems to resolve the "not so" funny stuff. This is part of the reason that I am changing over to LEDs except for the headlights. On one of my two wheelers I had a pair of bulbs drawing 54 watts. This total is the draw of both the running and brake lights. I have changed them to LEDs which are much brighter and the power draw is about 12 watts.

For those that may not know Magic Man has some top quality LEDs. I have compared his to two other brands. His are brighter and on close examination the quality of construction is far superior.
