Hi,

If anyone has information regarding the diagnosis of the average speed and =
miles per gallon function not working, I'd appreciate some help.  Also, the=
 cruise control doesn't work and the differential lock works but doesn't di=
sengage above 15 mph.  It kind of points to a bad sensor somewhere.

Any BTDT's would be great.  Thanks for the help.

Mike
