Windows: Description and Operation

With the ignition switch in the ON or START position, power is supplied
^ from 7.5 A fuse (No. (12) ,located in the fuse block in the HEC)
^ to BCM terminal (29).
Driver door control unit (LCU01) terminals (1) and (2) are connected to BCM terminals (38) and (33) by DATA LINES A and B. Also, driver door control unit terminals (11) and (12) are connected to front power window regulator LH terminals (2) and (1) respectively.
Rear LH door control unit (LCU04) and rear RH door control unit (LCUO3) terminals (1) and (2) are connected to BCM terminals (38) and (33) by DATA LINES A and B. Also, rear LH and RH door control unit terminals (15) and (16) are connected to rear power window regulator LH and RH terminals (2) and (1) respectively.
Passenger door control unit (LCU02) terminals (1) and (2) are connected to BCM terminals (38) and (33) by DATA LINES A and B. Also, passenger door control unit terminals (11) and (12) are connected to front power window regulator RH terminals (2) and (1) respectively.
BCM terminals (38) and (33) connected to multi-remote control unit (LCU05) terminals (1) and (3) by DATA LINES A and B.
When a power window switch is pushed, a signal is sent to BCM by DATA LINES. BCM sends a signal to all door control units and all door control units supply power and ground to all power window regulators

Control by remote controller
When multi-remote control unit receives DOWN signal from remote controller, the signal is sent to all door control units through BCM by DATA LINES. When door control units receive the signal, power and ground are supplied to all power window regulators.
