184002088 - E3051 ELECTRIC REAR WINDOWS - FUNCTIONAL DESCRIPTION

Operational description

The services relay T13, located in the junction unit under the dashboard B2, supplies the luggage compartment junction unit (which manages the rear electric windows) M63 pin A8 of connector A and pin B8 of connector B, with the logic described above and controlled by the Body Computer M1 pin 14 of connector F, via two lines protected by fuses F33 and F34.The junction unit is connected via the CAN line to the driver''s front door control unit M66.The unit H44 also incorporates the controls for the rear windows and the LOCK button: special analogue signals are sent to pins 27 of connector B and 1 and 3 of connector C of M66 (pin 33 of connector A provides the reference earth).With the LOCK button pressed the control unit M66 switches on the LED, located in H44 (from pin 7 of connector C). The control unit M66 converses via the CAN with control unit M63 which operates the motors N65 (left) and N66 (right). Similarly, the controls on the rear doors H53 and H54 send special analogue signals to control unit M63 to activate the motors N65 and N66.The control unit M63 is also connected to the Body Computer M1 via the CAN line and the instrument panel E50 to manage the "general failure" warning light if a problem is detected with the anti-crush sensors (function present up to June 2004).The RF aerial-receiver P93 sends the Body Computer M1 the opening/closing signal for the doors and for the windows and the sun roof as well, connecting to pins 21 and 31 of connector B    See E3040 CENTRAL LOCKING.
