Explanation
disconnection between output
transistor and component
exists.
DME final stage will set flag
whenever a short to ground, a
short to battery voltage or a
disconnection between output
transistor and component
exists.

During time out check no
signal was present within
specific time or faulty
information from serial
interface (parity, overrun,
etc.).
CAN message between
DME/EGS not received within
expected time.
