Airbag control unit with part number 169711

What does the airbag control unit 169711 do?

At the centre of the restraint system in Ferrari is the control unit 169711. It checks the signals from the crash sensors and decides within milliseconds in an accident which airbags and seatbelt pretensioners to trigger.

At the same time it monitors the entire system continuously and shows faults via the airbag warning light.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 169711 fail?

The most common cause is crash data stored on the 169711 after an accident, even if no airbag has deployed; a usual diagnostic tool does not erase it. Further causes are ageing components, moisture and corrosion, as well as voltage spikes.

The details:

• Ageing electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or jump-starting

Crash data alone says nothing about the condition of the hardware. That is what the test is for.

How can you tell that the 169711 is defective?

The airbag warning light in the instrument cluster indicates a defect in the 169711 by lighting up permanently or intermittently. Accompanying this, an error message appears, the diagnostic tool finds no connection, and the fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. The warning light makes the defect visible, and it makes sense to respond to it.
