SUN ROOF OPERATIONAL DESCRIPTION

Operational Description

The controls for the centre sun roof N155 and the rear sun roof N156 receive a supply, at pin 6, from the line for fuses F35 and F34, respectively, located in the additional fuse box B098.

The controls for the front sun roof N036, on the other hand, receive a supply at pin 6 of the body computer node M001 (pin 10 connector F) from the line protected by fuse F09.

Pins 1, 8 of N155, 1, 7 of N156 and 1 of N036 are earthed.

The electric motors N036, N155 and N156 interface with the CAN, from pins 4 and 5, communicating with the body computer node M001 at pins 11, 13 of connector I; they also receive a supply via the CAN, at pin 10, from the line protected by fuse F01 of the body computer M001.

The three sun roofs are opened and closed via switches H061, I120, I121 and I122.

Switch H061 controls the opening/closing of the front sun roof N036. Pin 2 receives a positive signal coming from pin 2 of the sun roof motor N036. By pressing the switch in position A, a signal is sent from pin 3 of H061 to pin 3 of N036, controlling the opening of the roof. In position B, the signal is sent from pin 6 of H061 to pin 9 of N036, controlling the closing of the sun roof.

Switch I120 controls the opening/closing of the centre sun roof N155. Pin 2 receives a positive signal coming from pin 2 of the sun roof motor N155. By pressing the switch in position A, a signal is sent from pin 3 of I120 to pin 3 of N155, controlling the opening of the roof. In position B, the signal is sent from pin 6 of H120 to pin 9 of N155, controlling the closing of the sun roof.

Switch I121 controls the opening/closing of the rear sun roof N156. Pin 2 receives a positive signal coming from pin 2 of the sun roof motor N156. By pressing the switch in position A, a signal is sent from pin 3 of I121 to pin 3 of N156, controlling the opening of the roof. In position B, the signal is sent from pin 6 of I121 to pin 9 of N156, controlling the closing of the sun roof.

A positive signal is supplied by pin 2 of the front sun roof N036 to pin 2 of the actual switch.

Pressing the switch in position A sends a signal from pin 3 of I122 at pin 3 of the centre sun roof motor N155 and from pin 1 of I122 to pin 3 of the rear sun roof motor M156, controlling the opening of both. Pressing the switch in position B sends a signal from pin 6 of I122 at pin 9 of the centre sun roof motor N155 and from pin 4 of I122 to pin 9 of the rear sun roof motor M156, controlling the closing of both.

Switch I122 controls the opening/closing of both the centre sun roof N155 and the rear sun roof N156.

Using the driver''s front switches H051, it is possible to disable both the opening/closing of the rear windows < R1 > and the controls for the centre and rear roofs.

See E3051 ELECTRIC REAR WINDOWS

The signal is supplied from pin 2 connector B of H051 to pin 11 connector A of the door node M066. The door node M066 informs the body computer node M001, via the CAN, of the command to exclude the rear windows and roofs.
