B2621 - Communication Interruption
DESCRIPTION
The multiplex tilt and telescopic ECU forms a network with the ECUs of other systems through the CAN communication bus. Each ECU informs the
other ECUs that it is connected to the network by outputting a specified signal (periodic signal) onto the CAN communication bus on a regular
schedule. The multiplex tilt and telescopic ECU detects the connection of each ECU based on the signal.
