1.2 8v, 1.3 Multijet, 1.4 16v

FUNCTIONAL DESCRIPTION

The brake pedal switch I030 (pin 4) receives an ignition-controlled supply (INT) from the line protected by fuse F37 of the Body Computer M001 (pin 7 of connector C): when the brake pedal is pressed, the N.A. switch (pin 2) closes and sends a signal to Body Computer (pin 27 of connector B).

The same signal is sent to the engine management control unit M010.

Body Computer M001 controls the power supply to the brake lights in the left F030 (pin 4) and right F031 (pin 2) rear light clusters, from pins 60 and 8 of connector F respectively.

The brake pedal switch I030 controls the middle brake light F040 directly without any control logic.

All the rear light clusters are connected to the left rear earth C030.

The Body Computer M001 receives a direct battery power supply (pin 1 of connector A) protected by fuse F01 of the engine compartment junction unit B001 (pin 18 of connector B); it also receives an ignition-controlled power supply (INT) at pin 11 of connector E.

The Body Computer M001 is also connected to the driver''s dashboard earth C015 via pins 9 and 10 of connector E.

Via the B-CAN line, the Body Computer M001 (pins 18 and 20 of connector D) is connected to the instrument panel E050 (pins 5 and 6) to manage the general failure warning light and the message in the display if there is a failure detected in the circuit or the fuse.
