Brake pedal switch I020 is supplied by the INT line protected by fuse F35 of the underfacia junction unit B002.

When reverse is engaged, the switch closes and sends power to the reversing light in the tail-lights (mobile part on the boot) F035 (left) and F036 ) right respectively, via control unit B002, from pins 7 and 8 of connector D.

The reversing light activation signal is sent to Body Computer M001 (pin 3 of connector F) and then repeated:

- via a discrete signal - from pin 1 of connector A - to stalk unit H005 and the electrochrome interior mirror P065;

- via the CAN netework - from pins 24 and 25 of connector H - to Connect Nav + P020 and from pins 5 and 7 of connector F - to parking sensor control unit M084 and driving attitude node M173.

2.2 · AUTOMATIC TRANSMISSION

The sensor unit on the gearbox L050 is supplied by the INT line protected by fuse F35 of the underfacia junction unit B002.

When reverse is engaged (gear lever on position R), the switch closes and sends power to the reversing light in the tail-lights (mobile part on the boot) F035 (left) and F036 ) right respectively, via control unit B002, from pins 7 and 8 of connector D.

The reversing light activation signal is sent to Body Computer M001 (pin 3 of connector F) and then repeated:

- via a discrete signal - from pin 1 of connector A - to stalk unit H005 and the electrochrome interior mirror P065;

- via the CAN netework - from pins 24 and 25 of connector H - to Connect Nav + P020 and from pins 5 and 7 of connector F - to parking sensor control unit M084 and driving attitude node M173.

1.9 JTD 16v, 2.4 JTD 20v

Automatic control unit M055 receives a 15/54 power supply protected by fuse F24 of engine compartment junction unit B001.

When reverse is engaged (gear lever in position R), control unit M055 sends an earth signal to relay T20 of engine compartment junction unit B001: via a line protected by fuse F35 of underfacia junction unit B002, the unit sends a power supply to the reversing lights in the tail-lights (mobile part on boot) F035 (left) and F036 (right), respectively, via control unit B002, from pins 7 and 8 of connector D.

The reversing light activation signal is sent to Body Computer M001 (pin 3 of connector F) and then repeated:

- via a discrete signal - from pin 1 of connector A - to stalk unit H005 and the electrochrome interior mirror P065;

- via the CAN netework - from pins 24 and 25 of connector H - to Connect Nav + P020 and from pins 5 and 7 of connector F - to parking sensor control unit M084 and driving attitude node M173.
