The Alfa D.N.A. system is being used for the first time on this model; it is an innovative device that acts on the vehicle dynamic control systems which was previously only used on competition and racing cars.

Alfa D.N.A. acts on the engine, brakes, suspension, steering and gearbox allowsing 3 different behaviour modes for the car to emphasize the most suitable driving style for the conditions or desired by the customer.

These modes are Dynamic (super sports), Normal (urban) and All Weather (maximum safety even in difficult grip conditions).

- Dynamic: ports driving mode.

- Normal: driving mode for normal conditions.

- All Weather: driving mode for poor grip conditions (rain, snow).

The system acts on all the vehicle dynamic control components:

- engine management control unit

- instrument panel

- ABS/VDC system control unit

- electric steering control unit

- suspension control unit (if fitted)

The three positions can be selected using a lever next to the gear lever.

The lever is the monostable type, in other words it always remains in a middle position (normal).

The vehicle configuration engaged is displayed by the LED lit up in the panel and by the instrument panel reading.

To engage the Dynamic mode, move the lever upwards; the lever will return to the middle position once it is released. To disengage the Dynamic mode, and return to Normal, repeat the same movement with the lever.

It is not possible to switch directly from Dynamic mode to All Weather mode and viceversa, it is always necessary to pass through Normal mode and then select the other configuration.

If Dynamic mode was on before a key-off, then the configuration will automatically return to Normal mode at the next key-on.

If, on the other hand, All Weather or Normal mode was on before switching off, the configuration will be maintained when the engine is next started.

Dynamic mode is automatically switched off when the vehicle speed exceeds 110 Km/h and then turned on again when the speed goes below this level.

If there is a system or selector failure, no configuration can be engaged and the message "mode not available" will be shown in the panel display.

  See descriptions 1056 PETROL INJECTION SYSTEM 

The d.n.a. system selector H139 sends an analogue signal to pin 56 of connector D of M001 depending on the mode selected.

The reference earth for this signal arrives from pin 25 of connector B of M001

Signals to light up the d and a LEDs of H139 respectively leave pins 31 and 1 of connector B of M001.

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.

The Body Computer M001 is connected, via the CAN, to the other nodes, in particular the steering control unit M086, the ABS-VDC control unit M050 and the engine management control unit M010.

It is also connected to the instrument panel E050 to which it sends the signals to display the mode engaged and the system failure.
