ADIRU 2 and APU Bleed

Why does the BLEED PSi go to double-amber Xs on the APU page when ADIRU 2 is offline?

Eight Air Data Modules (ADM) convert pneumatic data from the
Pitot and Static probes into numerical information for the ADIRU's, without knowing the ambient pressure it can not give you an accurate bleed pressure.
