Engine Warning Light - Silverleaf Message

2005 County Coach Intigue - Earlier today while checking in at the campground that we're staying at the engine warning light came on while parked outside the office. The Silverleaf display had the following message.


Engine Diagnostics

ID FMI N Description
84 2 1 Invalid VEH SPD Signal

0 0 0 NO Code


Once I put the Allison transmission in drive, it showed a 1 instead of the usual 5.

Finally, once we were parked we were unable to get the HWH Leveling System to level the coach either in the automatic or manual.

Any idea what the engine code means and is it related to the HWH System? Might there be a small leak in the system that is preventing the system from leveling and maybe restricting the transmission to first gear only. As we were arriving to the park, we haven't try to take it back on the road yet.

Thanks for any input.

sounds like the speed sensor went out if it is showing the coach is moving when its parked then it will not let you level it. you can try unplugging it then try to level or call someone to scan it. hope this helps

I just Googled the entire phrase and it came up with a couple of different references. I don't know what type of engine you have so I can't point you in the precise direction, but it does seem to indicate, for the couple I looked at, that it has something to do with a speed sensor. This is what I put in Google;

Try it and see if what comes up makes sense to you.

Hope this helped a bit,
