2401147 - E3051 ELECTRIC REAR WINDOWS - Functional description

Functional description

The services relay T13, located in the unit under the dashboard B2 , supplies with the above-mentioned logic and controlled by the Body Computer M1 - pin 14 of connector F - the rear electric windows unit M82 - pins A8 of connector A and pin B8 of connector B, via two lines, protected by the fuses F33 and F34. The control unit is connected via the CAN line to the front driver's door control unit M66. Unit H44 contains the rear window controls and the LOCK key: appropriate analogue signals are sent to pin 27 of connector B and 1 and 3 of connector C of M66 (pin 33 of connector A provides a reference earth). When the LOCK key is pressed, control unit M66 turns on the relevant led, again in H44 (from pin 7 of connector C ). Control unit M66 communicates via the CAN line with control unit M63 , which controls motors N65 (left) and N66 (right). Similarly, the controls on the rear doors H53 and H54 send special analogue signals to the control unit M63 to operate motors N65 and N66. Pins A5 and B3 of conector A of M63 and pins A4 and A6 of connector B of M63 receive signals from anti-crush sensors K19 and K24. The control unit M63 is also connected, via the CAN line, to the Body Computer M1. and to the instrument panel E50 to manage the general failure warning light if faults are detected in the anti-crush safety sensors. The aerial-receivier P93 sends the Body Computer M1 the signal to open/close the doors and also windows and sunroof, by connecting to pins 21 and 31 of connector B  See E3040  CENTRAL LOCKING .
