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 ; it 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 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 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 doodr - 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 door N50 and front passenger's door N51 , from pins 10 and 11 of connector F. Via the CAN line, the Body Computer M1 is connected to the instrument panel E50 , to which it sends a signal which, when necessary, lights up the 'doors open' warning light.
