939011632 - E3051 ELECTRIC REAR WINDOWS - FUNCTIONAL DESCRIPTION (High setup)

FUNCTIONAL 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 of B2.Pins B1 and C8 of connector A and pin A1 of connector B of M63 are earthed.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 relays the signal for switching on the relevant LED in H44 (from pin 7 of connector C); the control unit M66 then transmits these signals to control unit M63 via the CAN.Similarly, the controls at the rear doors H53 and H54 send dedicated analogue signals to the control unit M63 to pins B5 of connectors A and B.The control unit M63 operates the motors N65 (left) - from pins A1 and C1 of connector A and N66 (right) - from pins A8 and C8 of connector B.The signals for the anti-crush sensors K19 and K24 reach pins A5 and B3 of connector A of M63 and pins A4 and A6 of connector B of M63.The control units M63 is also connected via the CAN line to the Body Computer M1 and to the instrument panel E50 to manage the signal if there is a failure in the anti-crush safety sensors.
