2753514 - E2510 COURTESY LIGHTS - Functional description (Door lock)
Functional description
The front courtesy light G010 is supplied by the body computer node M001 (pin 10 connector F). The internal switch A can be turned to three positions:
- position 0: the switching on or off of the front courtesy light is managed by the body computer node;
- position 1: the front courtesy light is always off;
- position 2: the front courtesy light is always on.
The body computer node switches the front courtesy light on automatically in relation to the door signals coming from the door locks N050, N051, N055 and N056 in the following conditions:
- if the negative signal (with reference to earth C020 connector B) indicating the left front door opening is received at pin 23 connector H;
- if the negative signal (with reference to earth C020 connector B) indicating the right front door opening is received at pin 21 connector H;
- if the negative signal (with reference to earth C030) indicating the left rear door opening is received at pin 15 connector G;
- if the negative signal (with reference to earth C020 connector A) indicating the right rear door opening is received at pin 4 connector G;
- if the negative signal (with reference to earth C020 connector B) indicating the unlocking of the doors (central unlocking) is received at pin 13 connector H;
- if the negative signal (with reference to earth C030) indicating the operation of the inertia switch I050 is received at pin 14 connector G.
 | The connection between the body computer node and the front locks N050 and N051 passes through the door couplings D030 connector A and D031 connector A. Both are housed, in the passenger compartment area, in the lower part of the left or right front pillar (depending on the coupling involved), near the door cable duct. Door coupling D030 is located behind the body computer node. |
The body computer node switches the front courtesy light off automatically in the following conditions:
- if the door locking signal (with reference to earth C020 connector B) (central locking) is received at pin 12 connector H;
- if the negative signal (with reference to earth C030), indicating the reactivation of the inertia switch I050, is no longer received at pin 14 connector G.
The body computer node also manages the switching on/off of the boot courtesy light G040. From connector G, the body computer node:
- at pin 18, supplies the bulb housed inside the boot courtesy light G040;
- at pin 5, receives the negative signal (with reference to earth C030) indicating the opening of the tailgate, coming from the switch on the exterior handle I033;
- at pin 13, receives the signal (with reference to earth C030) indicating the incomplete closing of the tailgate, coming from the exterior handle switch I033.
| Earth C020 is fastened to the floor of the passenger compartment and is located near the right front wheel arch (footwell area). Earth C030 is fastened to the left rear wheel arch (passenger compartment interior). |
