CAN-bus / GMLAN
 
Anybody know if all VUEs made after a certain year use either the CAN-bus or GMLAN protocol? If so, what year did they make that switch?

Also, does the instrument cluster for the VUE (assuming CAN-bus or GMLAN is used) connect directly to the bus? or if not, how is it connected to receive its speed, tach, fuel, and temp information?

Thanks for your help.

This data bus stuff is over my head ... but I've got nothing better to do until temp climbs above zero and I can go outside and throw a frozen Frisbee to my idiot brain dog.

I've attached extract from 05 Vue FASM with data-bus information as well as BCM data related stuff.

I had a copy of IPC schematic but it continues to elude.

It looks like any '02-'07 uses the class 2 data bus to communicate between the BCM and the cluster. '08+ is low-speed GMLAN.
