The switch I30 receives an ignition-controlled supply (INT) from the fuse line F37 in the junction unit under the dashboard B2: when the brake pedal is pressed, the N.A. switch closes and sends a signal to Body Computer M1 ,pin 2 of connector F.

The Body Computer M1 receives a direct supply from the battery via the line protected by maxifuse B99 at pin 18 of connector F of the interface with the junction unit under the dashboard B2; the ignition-controlled supply (INT) reaches pin 9 of connector F of the interface with the junction unit B2.

The Body Computer M1 controls the power supply for the brake lights located in the light clusters F30 (left) and F31 (right) from pins 44 and 31 of connector E.

The switch I30 controls the 3rd brake light F40 directly via the junction unit under the dashboard B2, pin 5 of connector D.

The Body Computer M1 is connected via the CAN line to the instrument panel E50 to manage the lights failure warning light and the brake lights check signal if problems are detected in the circuit or in the fuse.
