Airbag control unit with part number P68170215AA

What does the airbag control unit P68170215AA do?

The airbag control unit P68170215AA is the central control unit of the restraint system (SRS) for Fiat. It evaluates the crash sensors and decides in an accident whether airbags and seatbelt pretensioners are triggered.

It works within fractions of a second and monitors the system continuously.

Detected faults are shown via the airbag warning light in the instrument cluster. After an accident the unit stores crash data and locks itself.

Why does the control unit P68170215AA fail?

Crash data stored after an accident is the most common cause, even if no airbag has deployed. Ageing components, cold solder joints, moisture at plug connections and voltage spikes are also involved.

An ordinary diagnostic tool cannot delete the crash data, so the stored data remains.

The other causes mainly concern the electronics and the connections. Ageing components and cold solder joints disrupt the function, while moisture and corrosion impair the contact.

Voltage spikes, for example from a weak battery or jump-starting, cause additional damage.

How can you tell that the P68170215AA is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. Signs at the P68170215AA also include fault messages and a diagnostic tool that cannot establish a connection.

You can recognise these signs in the vehicle:

• airbag warning light in the instrument cluster lights up
• fault message is displayed
• diagnostic tool receives no connection to the control unit
• fault memory cannot be cleared

As long as these signs persist, airbags and seatbelt pretensioners may not trigger in an emergency.
