my Igen4 started giving me 9-1100's out of nowhere... so. restart, clean everything... cleaner,etacs etc... wont pass 951. So restart again comes back with 06-4201. something to do with ROS? reboot full with power off... now i'm not getting the board status page... just "software initializing" next step?
According to my dusty notes that is a "ROS 1 (Magenta) Miscellaneous RCM Fault" Never had it happen on my 150, but it kinda sounds like something is going bad inside the ROS electronics. But if your board startup screen is not popping up it might just be a bad CRIM? Totally spit-balling on this.
