28SS Firefly I/O (G12) Board location

[WeQuit]

Our Firefly has ceased being able to see that the parking brake is set. Luckily, since slide and levelers have their own independent controllers, with apparently independent, parking brake inputs they're working from their respective panels. They just can't be controlled through multiplex. The awning, however, will not extend.

I'm hoping it's just a loose terminal on the board. I just can't find the board.

FYI on the newer RAM's, the parking break is now on their CANbus system....so it is a digital signal. It requires the Key to be in the ON position to see it.

So you are not getting a park brake signal with the key in the ON position?

I do know, we have a Y-cable now that is supposed to resolve this by getting it from a switch and NOT the CANbus.

We're pretty much fresh off the line, so should have the Y-cable installed. Awning behaved as such initially (RAM off, awning extended no problem). Slides and levelers still behave that way from their own control panels. Its just that Firefly can't see parking brake = ON anymore. I did try all key positions I could come up with just to see as part of my troubleshooting (key in ACC, key in On without brake so no engine start and engine start). I couldn't coax the awning to extend, but did manage to convince the levelers we were about to do something real dumb and they retracted.

As a side note, we do have 12V to awning because pressing retract does momentarily roll it up against its limit switch. Also, in the Firefly diagnostics screen it never shows the parking brake input coming on. So, I'm positive its something between RAM switch and Firefly I/O. I'll also try the key position test one more time when we get back to the RV Friday.
