CENTRAL LOCKING - FUNCTIONAL DESCRIPTION

Functional description

The door lock command, inside the Body Computer

M1

- pin 1 of connector F - has the supply line protected by fuse F38 in the unit under the dashboard

B2

; also has a dedicated earth connection: pin 20 of connector F.

The Body Computer M1 receives as input:

• the ''lock'' signals from the handles (or key in the lock) at pins 24 (driver''s front door - N50) and 17 (front passenger''s door - N51) of connector E.
• the ''release'' signals from the handles (or key in the lock) at pins 34 (driver''s front door - N50) and 35 (front passenger''s door - N51) of connector E.
• the ''door open'' signals at pins 8 (driver''s door - N50) and 25 (front passenger''s door - N51) of connector E;
• the signal from the lock/release button, located in the controls unit H12, at pin 2 of connector D; (the button is lit when the doors are locked by the ignition-dependent line (INT) of fuse F49 of unit B2 );
• the signals coming from the aerial-receiver P93, which is connected to pins 21 and 31 of connector A.

In accordance with the control logic described above, the Body Computer

M1 controls the lock motors of the driver''s front door N50 and front passenger''s door N51, from pins 10 and 11 of connector F.

Body Computer

M1

connects to instrument panel

E50

via the CAN line. The computer sends a signal that turns on the door open warning light when required.

The intervention of the inertia switch

I50 is signalled to pin 12 of connector A of E50 via the CAN line, the instrument panel E50 is connected to the Body Computer M1 and this signal causes the unlocking of the doors.
