Freightliner Century, no dashboard display

[Poptest]

I have Freightliner Century class which has no display on all dashboard gauges. Servicelink tool shows complete display on pc. I beleive ICU (instrument cluster unit) is ok due to the presence of display.

Please give me wiring info to check from ICU to gauges.

Many thanks!!!!!

Century instruments cluster works with data link j1587, if you have data link in the diagnostic port most is going to be a bad ICU. a little more info would be better, in the lcd display shows no data link? wich gaches works?
check the data link cables on the ICU.
