BRAKE LIGHTS - FUNCTIONAL DESCRIPTION

FUNCTIONAL DESCRIPTION

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 which "passes through" the junction unit under the dashboard B and reaches the Body Computer M1, pin 2 of connector F.

The Body Computer M1 controls the power supply for the brake lights located in the light clusters F30 (left) and F31 (right) from pins 32 and 22 of connector E.

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.

The switch I30 controls central brake light F40 directly without any control rules, via the junction unit under the dashboard B2, pin 5 of connector D.
