A control system utilizes a multiplex communication system for switchably operating power windows, power seats, power door locks, power mirrors, accessory lighting, etc. Switches mounted on the driver door and elsewhere communicate with a door-mounted microcomputer, which scans the state of each switch, prioritizes the requests, and issues commands in accordance with algorithms to control the windows, door locks, etc. The system has three modes of operation: Asleep, Active, and Awake. In the Asleep mode electrical power consumption is very small, and only a selected few input sesors are periodically monitored as to status. If a door handle is lifted or other action starts, the system changes to an Active mode, in which many more sensors are periodically scanned, and most output motors can be operated. In the Awake mode, windows can also be operated.
