The switching on of the front courtesy light G010 is managed by the Body Computer M001 which receives negative "door open" input signals respectively:- at pin 11 of connector B (driver''s front door, via the internal contact at the geared motor N050 - pin 1 -);- at pin 34 of connector B (passenger front door, via the internal contact at the geared motor N051 - pin 1 -);- at pin 22 of connector B (left rear door, via the internal contact at the geared motor N055 - pin 1 -);- at pin 35 of connector B (right rear door, via the internal contact at the geared motor N056 - pin 1 -);The front courtesy light G010 (pin 2 of connector A) is supplied by the Body Computer M001, according to the logic described previously, from pin 45 of connector B, whilst the analogue signal for controlling the timed/dimmed switching on/off arrives from pin 30 of the same connector (pin 3 of connector A of G010).In the same way the rear courtesy light G020 is supplied by the Body Computer M001 from pin 45 of connector B, whilst the analogue signal for controlling the timed/dimmed switching on/off arrives from pin 29 of connector B.The front courtesy light is backlit by an LED: with the side lights on, G010 receives a power supply, at pin 1 of connector B, from pin 52 of connector B of the Body Computer.The Body Computer receives a power supply from the battery, via the line protected by fuse F1 located in the engine compartment junction unit B001. It also receives an ignition-controlled power supply (INT) from the ignition switch H001. The reference earth reaches pins 10 and 19 of connector A 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.
