The brake pedal switch I030 is supplied by the line INT protected by fuse F42 of the Body Computer M001 (pin 28 of connector D): when the brake pedal is depressed, the "N.O." switch closes and sends a signal to the Body Computer M001 (pin 57 of connector D).

Body Computer M001 controls the power supply to the brake lights in the left F030 (pin B) and right F031 (pin D) tail-lights and the central stop light F040, from pins 2, 32 and 48 of connector F respectively.

Via the CAN line, the Body Computer M001 (pins 11 and 26 of connector B) is connected to the instrument panel E050 (pins 5 and 6) to manage the "exterior lights failure" warning light and the message in the display if there is a failure detected in the circuit, the bulbs or the fuse.
