DESCRIPTION
The multiplex tilt and telescopic ECU forms a network with the ECUs of other systems via CAN communication. Each ECU informs the other ECUs that it is connected to the network by sending a specified signal (periodic signal) onto the communication bus on a regular basis. The multiplex tilt and telescopic ECU receives vehicle speed signals from the combination meter assembly via the CAN communication bus to prevent improper operation of the auto away/return function while driving.
