FUNCTIONAL DESCRIPTION

Switch I030 receives an ignition-controlled supply from the line for pin 7 of connector C of the Body Computer M001 via the line for fuse F37 of the Body Computer M001: when the brake pedal is pressed, the switch closes and sends an N.A. signal to Body Computer M001, pin 27 of connector B of M001.

The Body Computer M001 consequently controls the power supply for the brake lights in the lamps F030 (left) and F031 (right) from pins 10 and 8 of connector F.

The middle brake light F040, on the other hand, is controlled directly by switch I030.

The Body Computer M001 - connector A - receives a direct powr supply from the battery through the line protected by maxi fuse F01 of the engine compartment junction unit B001.

The Body Computer M001 receives an ignition-controlled power supply (INT) at pin 11 of connector E.

Pin 9 of connector E of M001 provides the Body Computer with a reference earth.

Body Computer M001 is connected via the CAN line to the instrument panel E050 to manage the lights failure warning light and the brake lights check signal if problems are detected in the circuit or in the fuse.
