FOG LIGHTS - Functional description

Functional description

The fog lights activated signal reaches pin 1 of connector D of M1 from the control button in the centre panel H90.

The side lights activated signal is sent to pin 28 of connector G of the Body Computer M1 from the steering column switch unit H5See E2010 SIDE LIGHTS / NO. PLATE LIGHTS.

The 'ignition ON signal (INT) for the switch H1 reaches the underdashboard control unit B2 at pin 11 of connector H and from there moves on to the Body Computer M1 (pin 9 of connector F).

The Body Computer M1 controls the supply for the fog lights by sending an earth signal to the engine compartment control unit B1 from pin 8 of connector A of M1 which energizes the relay T14: this supplies the fog lights F10 (left) and F11 (right). The circuit is protected by fuse F30 of control unit B2.

The Body Computer M1 is connected, via the CAN line, to the instrument panel E50 to manage the main beam headlamps warning light.
