E3060 Sun roof

Description

The sunroof offers extra ventilation for the interior compartment and ensures a rapid air exchange, if required, thus increasing passenger comfort.

The system is operated by a knob, located near the front courtesy light.

The operating logic of the roof is controlled by a specific control unit which receives the signals from the control knob and roof operating motor.

By turning the knob in the direction shown by the arrow, the roof slides open: you can choose between 5 available open positions; to close the roof, return the knob to the central position.

The sunroof has a blind which slides manually; however, it is towed by the roof when the roof is opening; during closure, the blind comes out partially so that the grab handle is accessible.

When the knob is turned in the opposite direction to that shown by the arrow, the rear part of the roof opens upwards: you can choose one of 3 available open positions; to close the roof, return the knob to the central position.

Pressing the knob interrupts any movement (inhibition position).

The roof's control electronics also has an anti-collision function: during roof closure, the movement is stopped and reversed by about 10 cm if - via a Hall-effect sensor located on the engine - an obstacle is detected.

This function can be excluded - for safety reasons - by pressing the knob as described above.

The circuit is protected by a specific fuse in the additional fusebox.

The roof is automatically closed - with a signal which reaches via the CAN network - also if the climate control unit is set to recirculation and the ignition is ON (recirculation can be activated manually or by the exhaust gas sensor Wiring diagram E6020 AIR CONDITIONER ).

The roof is also automatically closed - if left open - via a specific prolonged command (over 4 seconds) sent by the remote control button, if the ignition is off; for more details Wiring diagram E3040 DOOR LOCKING DEVICE .

Description of operation

The sunroof control unit M83 is supplied at pin 4 by the line protected by fuse F60 of the fuse box B98, via the line protected by fuse F46.

The automatic roof closure signal arrives from 10 of connector E of Body Computer M1, in accordance with the above-mentioned logic.

The speedometer signal, used by the internal logic of the control unit M83, arrives from pin 23 of connector C of Body Computer M1.

Via the CAN line, the Body Computer M1 is connected to the climate control unit M70, from which it receives the recirculation signal Wiring diagram E1050 CAN CONNECTION LINES .

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 A.
