DTC B2621 Communication Interruption

DESCRIPTION





The multiplex tilt and telescopic ECU forms a network with the ECUs of other systems through the communication bus. Each ECU informs the other ECUs that they are connected to the network by outputting a specified signal (periodical signal) to the communication bus at a regular basis. The multiplex tilt and telescopic ECU detects the connection of each ECU based on the signal.
