DESCRIPTION - SUN ROOF - Fiat BRAVO 1.9 JTD 16v

The sun-roof provides a means of extra passenger compartment ventilation and ensures swift air exchange when necessary for improved passenger comfort.The extensive glazed sun roof is composed of two glass panels, one fixed and one moving, with two manuall operated sun blinds (front and rear).The system is operated by a dual switch located near the front courtesy light that controls a motor with two different operating modes: "hinged" raising of the roof and sliding opening of the roof.Roof movement is controlled manually and automatically in accordance with the following strategy:- if the button is pressed is between 60 and 300 milliseconds, operation is manual: the roof moves only with the key pressed;- f the key is pressed for longer than 300 milliseconds, operation is automatic: even if the button is released, the glass continues to move up/down until the end of travel position is reached or until the intervention of the anti-pinch safety system;- pressing the button again whilst the window is moving stops it in the position it is in;- if the button is pressed for less than 60 milliseconds, this is ignored (it is treated as an accidental knock).The electronic roof control circuit also includes an antipinch function: when the roof is closing, the movement is interrupted and reversed for about 10 cm if an obstacle is detected by means of a Hall effect sensor located on the motor.Sun roof movements via the control key are allowed only with key on.768Initialization of the system:If the power supply has been disconnected, the following reset procedure must be carried out for the roof:- turn the ignition key to the ON position;- press the closing button until the roof is completely shut; then release the button;- press the button and keep it pressed for at least 10 seconds and/or until the glass panel can be heard to move forwards; then release the button;- press the button again within 5 seconds of the previous action and keep it pressed: the panel will perform one complete opening and closing cycle;- release the button at the end of this cycle.The initialization cycle is complete.

FUNCTIONAL DESCRIPTION - SUN ROOF - Fiat BRAVO 1.9 JTD 16v

The services relay T13, located in the junction unit under the dashboard B2, supplies the sun roof control motor N35 - pin 6 - via the line protected by fuse F46 of B2 through the logic described above and controlled by the Body Computer M1 - pin 14 of connector F; the ignition-controlled supply (INT) for fuse F49 in the junction unit under the dashboard reaches pin 3 of N35.The same ignition-controlled supply (INT) for fuse F49 is sent to the control button H60, pin 4.The control signals from switch H60 are sent to pin 5 (opening) and to pin 10 (closing) of N35.The speedometer signal reaches pin 8 of N35 from pin 17 of connector D of the Body Computer M1; pin 1 of N35 is earthed.The Body Computer M1 receives a direct supply from the battery via the line protected by maxifuse B99 at pin 18 of connector F of the interface with the junction unit under the dashboard B2; the ignition-controlled supply (INT) reaches pin 9 of connector F of the interface with the junction unit B2.
