841004212 - E3050 FRONT ELECTRIC WINDOWS OPERATIONAL DESCRIPTION

Operational Description

When excited by Body Computer M001, service relay R13, located in underfacia junction unit B002, supplies the front window controls on the two driver side door and passenger side door control units (M066 and M067) by means of two lines protected by fuses F47 and F48 respectively.Front driver side door control unit M066 communicates via the B-CAN network with instrument panel E050 and with other control units involved in the function via pins 31 and 32 of connector C.Driver side window motor N060 (and also passenger side window motor N061) is connected to the relevant door control unit at pins 8 and 9 of connector B. The antipinch sensor on the front driver''s side door K022 (K023 for the passenger side) is connected to the door control unit at pin 7 of connenctor A and 39 of connector C. Any sensor faults are sent via the B-CAN network to the instrument panel (pin 3 and 4 of connector A), which indicates a message on the display.Climate control unit M070 (Wiring diagram E6020 AIR CONDITIONER) communicates the presence of exhaust gas to Body Computer M001 (pins 24 and 25 of connector D) via the B-CAN network. At this point, door control units M066 and M067 download the commands and activate window closure while internal air recirculation is activated.    See E6020 AIR CONDITIONINGA signal from rain and dusk sensor K125 leaves via the A-BUS line from pin 4 of connector B of ceiling control unit M062. The signal is processed by the Body Computer M001 and sent (pin 7 of connector F) to the door control units.The central lock/open signal reaches pins 21 and 31 of connector B of the Body Computer from the remote control unit via alarm and door lock aerial P093. This signal is sent via the B-CAN network from the Body Computer (pins 5 and 7 of connector H) to front door control units M066 and M067 (pins 31 and 32 of connector C).Body Computer M001 receives an INT/A (key-on) signal from ignition switch H001 at pin 27 of connector D via fuse F31 of underfacia control unit B002.
