FUNCTIONAL DESCRIPTION

The locking/unlocking of the doors function is controlled by the Body Computer M001.

The Body Computer M001 - connector A - receives a direct powr supply from the battery through the line protected by maxi fuse F01 of the engine compartment junction unit B001.

The Body Computer M001 receives an ignition-controlled (INT) power supply at pin 11 of connector E, whilst pin 9 of connector E of M001 provides the Body Computer with a reference earth.

Body Computer M001 receives the following inputs:

- the lock/release signals from the aerial-receiver of remote control P093, which are connected to pins 31 and 46 of connector F of M001;

- the lock/release signals from the pawl and/or lever located in the lock N050, at pin 51 of connector B of M001.

- the negative signal from the locking/unlocking button, located in control unit H090, at pin 39 of connector D of M001.

According to the control logic illustrated, the Body Computer M001 controls the two geared motors for the locks N050 and N051 via the line supplied by fuse F38 of the Body Computer M001:

- a shared power supply is sent to the motors from pin 31 of connector C;

- the locking/unlocking motor (B/S) are activated from pin 16;

- the dead lock motors (DL) are activated from pin 32.

The signalling LED located in the controls H090 is lit up by a signal from pin 11 of connector D of M001; the reference earth reaches pin 6 of H090 from pin 49 of connector D of M001.

Body Computer M001 is connected via the CAN line to instrument panel E050, 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.
