939004659 - E3040 CENTRAL LOCKING - FUNCTIONAL DESCRIPTION (Right hand drive, High setup)

FUNCTIONAL DESCRIPTION

The door locking/unlocking function is controlled by the control units for the driver''s door M66, passenger side M67 and luggage compartment M63 all connected via the CAN line to one another and to the Body Computer M1.The control units M66 and M67 receive a power supply at pin 11 of connector D from the line protected by fuse F32 of the junction unit under the dashboard B2, the luggage compartment junction unit M63 at pin B8 of connector A from the line protected by fuse F36 of B2.Pin 19 connector B and 7 of connector D of M66 and of M67 are earthed.Pin C8 of connector A of M63 is also earthed.Control units M66 and M67 receive the following input:- the "locking" signals from the knobs at pin 23 of connector B of M66 and M67; (the knobs for the rear doors send the signal to the passenger side control unit M67;- the locking/unlocking signals from the emergency key pawl, at pins 24 and 25 of connector B of M66;- the negative signal from the locking/unlocking button, located in the controls on the tunnel H35, at pin 34 of connector A of M66.According to the control logic illustrated, the control units M66 and M67 control the geared motors for the front door locks: the joint power supply for the motors is sent from pin 6 of connector D; the locking/unlocking motors (B/S) are operated from pin 4 of connector D; the dead lock motors (DL) for locks N50 and N51 are operated from pin 3 of connector D.Similarly the control unit M63 receives control signals from pins 10, 11 and 26 of connector B of M67 and controls the geared motors for the rear door locks: the joint power supply for the motors is sent from pin A7 of connector A and A2 of connector B; the locking/unlocking motors (B/S) are operated from pin C7 of connector A and C2 of connector B; the dead lock motors (DL) for locks N55 and N56 are operated from pin C6 of connector A and C4 of connector B.The signalling LED E40 is lit up by a signal from pin 8 of connector C of M66, whilst a reference earth is sent from pin 6.The activation of the inertia switch I50 is indicated at pin 17 of connector D of the Body Computer M1 : this signal, as described previously, causes the opening of the doors.
