Interbus...On our cars all the controls are modular and are connected together on a service called Interbus. When the module for the air looses communication it shuts the whole card down, skips over it. That card controls the inputs and outputs of the air, that is why nothing works...until it reconnects to the service. Mine did the same thing. They do this to make it easier to add or remove different options.
