Brake pedal switch I030 is supplied by the INT line protected by fuse F37 of the underfacia junction unit B002: when the brake pedal is pressed, the N.O. switch closes and sends a signal to Body Computer M001 (pin 2 of connector F).The signal that the key inserted and turned ON in the igntion (INT) reaches underfacia junction unit B002 (pin 11 of connector H) and from here passes to Body Computer M001 (pin 9 of connector F).Body Computer M001 controls the power supply to the brake lights in the tail-lights F030 (left) and F031 (right) from pins 32 and 22 of connector E respectively..Body Computer M001 (pin 5 and 6 of connector I) connects via the CAN line to instrument panel E050 (pins 3 and 4 of connector A) to control the exterior lighting fault warning light and the message on the display in the event of faults in the circuit, bulbs or fuse.Brake pedal switch I030 controls central brake light F040 directly without any control rules, via underfacia junction unit B002, pin 5 of connector D.
