I have a 4.1-C adapter, running firmware 3.23 and Blue-fire app software 11.2.2 on a 10" iPad Pro.I receive no fault info, although there is a check engine light and the 2000 Winnebago Journey is in limp mode.  One time while in the settings screen, the fault icon blinked a couple of times, but when I opened the fault screen, the screen froze and I had to close the app and restart it to escape the frozen screen.  How can I get the fault code, please?
