Communication Method; Multi-Distribution Input/Output By Circuit - Mitsubishi LANCER EVOLUTION-VII 2001 Technical Information Manual

COMMUNICATION METHOD

The exclusive signal lines for transmitting the multi-distribution data are connected as follows between
the ETACS-ECU, column switch (incorporated inside the column ECU), front ECU, power window main
switch (incorporated inside the power window ECU) and power window motor assemblies (incorporated
inside the power window motor ECU) for internal communication.
