why? no reason,just kicks?
vic, ( jeeps name for dah cluster)? veh. info center?
vic is upgrade over gdm base.
with means unplugged, sure.
93 no vic.
if you mean drive car with no cluster?
well, why not unplug it ,drive and tell us.?(holding breath)lol
the pcm programing on all years is a very complex topic.
issues, vss, and odometer sync,
got immoblizer, vtss or skim?
the fsm is here
but mostly they dont cover hacking. (your hacking right?)
this says that the cluster shows last odometer , if ccd fails.
so implies it runs to me... but?:

i can only guess at your cars options, so will get all this wrong.
but ill look at wring to vic.
the cluster 8w-40 chapter
is 100% digital in that all data is sent from pcm to cluster
via serial bus, ccd paired network
so the question is,when the pcm boots, and the cluster is dead
how angry will pcm be, answer, is wild guessing, no skim
is it runs. and barfs dtc errors, like mad(it will)
one way to kill pcm is if that pcm/bcm (some do) can not sync
the odometer, so it sees that is hacking (miles total) and shuts you down. some years do, mine does.
but all years and all options, dang you stumped me;.
as you may not know, added security options cause most jeeps
to go to ligher levels of crosschecking
and then cuts fuel if hacking is detected.
