What E91 reports

E91 stands for a user interface protocol incongruence error: the interface and the rest of the electronics are not speaking the same protocol.

Applies to

  • Current generation

Communication between boards is examined by a technician, not by the owner.

Look-alike codes

  • E92: protocol incongruence between the user interface and the mother board
