CENTRAL LOCKING - FUNCTIONAL DESCRIPTION

5 door

FUNCTIONAL DESCRIPTION

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.
