I'm working on a Carrier 40x, (engine driven) and the cab command will not power up in standby or road modes.
I've checked continuity through the emergency switch (it works) swaped out cab commands, data cables, and even the micro.
The unit has 14vdc when plugged in into the micro and power in and out of the mp34 and mp40 wires. I even tried suppling power to the s.key wire, still nothing.
I'm out of ideas, anyone else?
