Airbag control unit with part number 470959655

What does the airbag control unit 470959655 do?

The airbag control unit 470959655 controls the restraint system (SRS) of Lamborghini. It evaluates the crash sensors, determines within milliseconds in an accident the triggering of the airbags and seatbelt pretensioners, and monitors the system continuously.

The unit shows faults via the airbag warning light. After an accident it stores crash data and locks itself.

In everyday use the control unit works in the background and reports anomalies.

Why does the control unit 470959655 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. For the 470959655, Airbag24 erases this data during the repair.

A normal diagnostic tool does not erase this data.

Aged electronic components, cold solder joints and corrosion on plug connections are further causes. They develop over time.

Moisture and voltage spikes, for example from a weak battery or a jump start, also belong here.

How can you tell that the 470959655 is defective?

The airbag warning light in the instrument cluster shows the defect in the 470959655 by lighting up constantly or intermittently. In addition there is a fault message in the instrument cluster, no connection to the diagnostic tool and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may fail to trigger after such a defect. Please check the message promptly.

The warning light is the direct display of this condition in the vehicle.
