CENTRAL LOCKING - Functional description

High setup

Functional description

The door locking/unlocking function is controlled by the driver's door control unit M66, passenger side control unit M67 and luggage compartment M63, all connected, via the CAN line, to the Body Computer M1.

Control units M 66 and M67 are supplied- at pin 11 of connector E - from a line protected by fuse F36 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 F32 of B2.

Pin 19 connector B and 7 of connector E of M66 and M67 are earthed.

Pin C8 of connector A of M63 is also earthed.

Control units M66, M67 and M63 receive the following inputs:

• the 'lock' signals from the knobs, at pin 23 of connector B of M66 and M67;
• the 'lock' signals from the knobx, at pin B4 of connector A and B4 of connector B of M63;
• the locking/unlocking signals from the key pawl, at pins 24 and 25 of connector B of M66;
• the negative signals fromt he locking/unlocking buttons, located in the control unit on the tunnel H35, at pins 34 and 35 of connector A of M66;
• the signals coming from the aerial-receiver P93, which is connected to pins 21 and 31 of connector B of M1.

In accordance with the control logic described, control units M66 and M67 control the geared motors for the front door locks: the shared power supply is sent from pin 6 connector E to the motors; the locking/unlocking motors (B/S) are operated from pin 4 of connector E; the dead lock motors (DL) for locks N50 and N51 are operated from pin 3 of connector E.

Similarly, control unit M63 controls the geared motors for the locks for the rear doors: the shared power supply is sent to the motors from pin A7 of connector A and A2 of connector B; the locking/unlocking (B/S) motors 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 LED next to the controls on the tunnel H35 is operated by a positive command from pin 8 of connector C of M66.

Fuel flap opening motor N58 is controlled via the same strategy as that used for the front driver's door catch from pins 5 and 12 of connector E of M66.

The aerial-receivier P93 sends the Body Computer M1 the signal to open/close the doors and also windows and sunroof, by connecting to pins 21 and 31 of connector B.

Intervention of inertia switch I50 is indicated to pin 17 of connector D of Body Computer M1: this signal also causes door opening.

Functional description

The door locking/unlocking function is controlled by the driver's door control unit M66 connected, via the CAN line, to the Body Computer M1.

The control unit M66 is supplied at pin 7 of connector C from the line protected by fuse F36 of the junction unit under the dashboard B2 and at pin 2 of connector C by the line protected by fuse F32 of B2.

Pins 1 and 8 of connector C of M66 are earthed.

Control unit M66 receives the following inputs:

• the 'lock' signals from the knobs, at pins 9 and 8 of connector B of M66;
• the locking/unlocking signals from the key pawl, at pins 1-2 of connector B of M66;
• the negative signals from the locking/unlocking buttons, located in the control panel on the tunnel H35, at pins 3 and 4 of connector B of M66;
• the signals coming from the aerial-receiver P93, which is connected to pins 21 and 31 of connector B of M1.

In accordance with the control logic illustrated, the control unit M66 controls the geared motors for the door locks: the shared supply to the motors is sent from pin 4 and 12 of connector C; the locking/unlocking motors (B/S) are operated from pins 9 and 5 of connector C; the dead lock motors (DL) for the four locks N50, N51, N55 and N56 are operated from pins 3 and 11 of connector C.

The LED next to the controls on the tunnel H35 is activated by a positive command from pin 13 of connector A of M66.

Fuel flap opening motor N58 is controlled via the same strategy as that used for the front driver's door catch from pins 6 and 10 of connector C of M66.

The aerial-receivier P93 sends the Body Computer M1 the signal to open/close the doors and also windows and sunroof, by connecting to pins 21 and 31 of connector B.

Intervention of inertia switch I50 is indicated to pin 17 of connector D of Body Computer M1: this signal also causes door opening.
