COMMUNICATION OUTLINE
Communication is made among the instrument, power seat, remote control mirror, and telescopic ECUs.
When the ECU receives a signal from related switches, i.e., the driving position memory SW, the instrument ECU sends signals to the power seat, remote control mirror, and telescopic ECUs, and moves each part to the position set by the driving position memory SW.
For details, please refer to the new car features and/or the repair manual.
