DESCRIPTION - CENTRAL LOCKING - Fiat GRANDE PUNTO 1.4 16v
The simultaneous operation of the four door locks takes place via:- the remote control;- the key inserted in the catch on the driver''s door;- the locking/unlocking button in the centre console.The remote control unit has 3 buttons that allow the operation of the central locking system: a button for unlocking the doors, one for locking the vehicle and one for releasing the boot
FUNCTIONAL DESCRIPTION - CENTRAL LOCKING - Fiat GRANDE PUNTO 1.4 16v
The door lock/release function is controlled by Body Computer M1.Body Computer M1 receives the following input:- lock/release signals from the aerial-receiver of remote control unit P93, which are connected to pins 1 and 2 of connector K of M1;- lock/release signals from the key pawl located in lock N50, at pin 29 of connector A of M1;- the negative signal from the lock/release button, located in control unit H90, at pin 39 of connector D of M1; a reference earth reaches pin 5 of H90 from pin 49 of connector D.Body Computer M1 - connector G - is supplied directly from the battery from a line protected by maxifuse F2 of engine compartment control unit B1. It is supplied by an ignition-operated supply (INT) at pin 32 of connector D; pin 10 of connector H of M1 provides the Body Computer with a reference earth.According to the control logic illustrated, Body Computer M1 controls the geared motors for the four door locks: the joint power supply for the motors is sent from pin 19 of connector E; the locking/unlocking motors (B/S) are operated from pin 17 of connector E; the dead lock motors (DL) for locks N50, N51, N5 and N56 are operated from pin 18 of connector E.The signal LED in control unit H90 is turned on by a signal from pin 1 of connector D of M1.The activation of the inertia switch I50 is indicated at pin 23 of connector A of the Body Computer M1 : this signal, as described previously, causes the opening of the doors.Body Computer M1 is connected via the CAN line to instrument panel E50, to which it sends a signal that turns on the door open warning light, where necessary, and activates the buzzer to give an acoustic signal.
