The boot opening function is controlled by the Body Computer M1 and activated by the central locking power module M80 controlled by the Body Computer M1.Body Computer M1 receives the following inputs:- door lock/release signals from the aerial-receiver of remote control unit P93, which are connected to pins 30 and 43 of connector B of M1;- the negative signal from the boot unlocking button, located in the control unit H90, at pin 22 of connector H of M1;- the negative signal from the button in the rear handle I33, from pin 47 of connector E of M1.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.The central locking power module M80 receives a power supply from the line protected by fuse F36 of the junction unit under the dashboard B2.Depending on the operating logic illustrated, the Body Computer M1 operates the central locking power module M80 which, in turn, activates the geared motor in the boot lock via a relay: the command is sent from pin 41 of connector E to the module M80 which, in turn, activates the motor for lock N57.Body Computer M1 is connected via the CAN line to instrument panel E50, to which it sends a signal that turns on the boot open warning light, where necessary, and activates the buzzer to give an acoustic signal.
