This is.a Crown RC5535-35 Both drive and hydraulic are AC and unit is equipped with an factory installed extra infotainment display that has been inoperable for years. The battery was replaced with a new one 6 months ago and tests good. While being used unit died and a code 733 was reported by operator. Upon arrival unit will turn on and engage K2 relay but will not pull either contactor. The LCD section of the display is also completely blank (so no access to diagnostics, etc), but the BDI and all icons on display work. I replaced Access 7 as CAN readings were high but still have the issue. I am however getting a different flash code from the access 7 itself now. So my first question would be, is the flash code on the Access 7 the same as the unit fault codes? As I can't find any answer in the manual.
