Description - BOOT AND FUEL FLAP OPENING - Alfa Romeo GT 1.8 T.SPARK


The boot open motor is operated by:the button on the dashboard;the remote control.The control unit built into the commands unit on the door controls the operation of the boot lock release: it receives the request to open the boot from the Body Computer or from the control signal from the relevant button on the dashboard., and consequently issues a command to an external relay, located under the dashboard behind the Body Computer.The boot opening logic is as follows:when the ignition is on, the control button causes the boot to open if the vehicle speed is 0 km/h;with the ignition off, or when one of the doors is opened, the control button operates for a timed period of 3 minutes.Whenever the control button is pressed, a confirmation beep is issued - via a signal transmitted on the CAN - by the instrument panel buzzer.The remote control receiver aerial is connected directly to the Body Computer which contains the electronics of the receiver proper: the remote control is located in the key, on which a specific button controls the boot release (a further two buttons control the door lock and release]). The Body Computer receives the boot open request from the remote control and, with the ignition off, sends the command to the unit on the door.The operation of the geared motor opening the fuel flap takes place via the special button in the centre console.The Body Computer controls the operation of the fuel flap release in accordance with the following logic: the control is disabled:with the ignition ON;if the doors are closed and locked from the outside.
