DESCRIPTION
The multiplex tilt & telescopic ECU forms a network with the ECUs of other systems through the communication bus. Each ECU informs the other ECUs that it is connected to the network by outputting a specified signal (periodical signal) onto the communication bus on a regular schedule. The multiplex tilt & telescopic ECU receives vehicle speed signals from the combination meter via BEAN to prevent improper operation of the auto away/return function during driving.| DTC No. |
