There is a single (earth) signal sent by the steering column stalk H005 to the Body Computer M001 that manages the left and right direction indicators: from pin 5 of connector A of H005 to pin 57 of connector H of connector B of M001; the signal sent is coded by means of a resistive divider so that multiple information can be sent by the steering column stalk to the Body Computer via a single connection.

A reference earth reaches pin 4 of connector A of steering column stalk H005 from pin 45 of connector H of the Body Computer M001.

The hazard warning lights activation signal reaches pin 55 of connector H of M001 from the hazard warning lights control button in the centre switch panel H090 (pin 5).

The centre switch panel H090 is connected, via pin 4, to the centre dashboard earth C022 (connector A).

The Body Computer M001 manages the activation of the direction indicators respectively:

• from pin 31 of connector D, the direction indicator in the left light cluster F010 (pin 3);

• from pin 46 of connector D, the direction indicator in the right light cluster F011 (pin 3);

• from pin 19 of connector F, the side direction indicator in the driver's door mirror P060 (pin 1 of connector A) and the direction indicator in the left rear light cluster F030 (pin C);

• from pin 18 of connector F, the side direction indicator in the driver's door mirror P061 (pin 1 of connector A) and the direction indicator in the right rear light cluster F031 (pin B).

Via the CAN line, the Body Computer M001 (pins 11 and 26 of connector H) connects to the instrument panel E050 (pins 5 and 6) to manage the direction indicators warning lights, the buzzer and, if faults are detected in the circuit or bulbs, the exterior lighting warning light, in addition to the message in the display.
