Is it possible to operate the ZE-NC4612 with the ignition of the vehicle (ACC) in the Off position?

Answer: No, this ZENEC E>GO device requires ignition (and CAN net) to be powered on to operate.

CAN data is only present in the vehicle, when ignition status is on – for this reason operation of the unit is not possible when ignition of the car has been set to its off position.
