DescriptionThe front and rear door lock motors are activated simultaneously through the use of:the ignition key;the driver's front door switch (knob);the remote control.Locking operation: using the ignition key in the driver's front door, or using the remote control, when the doors are firmly shut, all the doors are locked simultaneously.Unlocking operation: using the ignition key in the driver's front door, or using the remote control, all the doors are unlocked.This operating logic is controlled by the body computer node.
Functional description The central locking function is entirely managed by the body computer node M001 which controls the locking/unlocking of the doors depending on the command received by the remote control (where available) or from the driver's front door lock N050.To lock the doors, the body computer node:from pin 12 connector H receives the negative door locking signal (with reference to earth C020 connector B) supplied by the front driver's door lock N050 (pin 6);from pin 7 connector M supplies the electric motors for the front door locks N050 and N051;from pin 10 connector E supplies the electric motors for the rear door locks N055 and N056.767 Earth C020 is fastened to the passenger compartment floor and is located near the right front wheel arch (footwell area).To unlock the doors, the body computer node:from pin 13 connector H receives the negative door unlocking signal (with reference to earth C020 connector B) supplied by the front driver's door lock N050 (pin 3);from pin 6 connector M supplies the electric motors for the front door locks N050 and N051;from pin 9 connector E supplies the electric motors for the rear doors N055 and N056.767 The power supply for the electric motors for each individual door lock (front, rear and boot) is protected by fuse F38; the door locking/unlocking logic is managed by a relay incorporated in the body computer node. The body computer supplies the electric motor for the boot lock N057 from pin 2 connector E. The command for opening the tailgate arrives from switch I033 at pin 5 connector G of the body computer node M001 (see wiring diagram E2510).The body computer node also checks that each individual door is correctly shut by means of the signals supplied by the internal (normally open type) switches for the door locks.More precisely, one door is considered as open (or not properly shut) when the body computer:receives a negative signal, from pin 23 connector H, (with reference to earth C020 connector B), coming from lock N050 (driver's front door check);receives a negative signal, from pin 21 connector H, (with reference to earth C020 connector B) coming from lock N051 (passenger front door check);receives a negative signal, from pin 4 connector G, (with reference to earth C020 connector A), coming from lock N056 (right rear door check);receives a negative signal, from pin 15 connector G, (with reference to earth C030), coming from lock N055 (left rear door check).receives a negative signal, from pin 13 connector G, (with reference to earth C030), coming from switch I033 (tailgate check, See E2510 COURTESY LIGHTS ).767 Door couplings D030 and D031 are housed in the lower part of the front pillar (right or left depending on the coupling involved), near the door cable duct.
