Airbag control unit with part number 1390300080

What does the airbag control unit 1390300080 do?

The airbag control unit 1390300080 controls the restraint system (SRS) of Fiat and Opel. It evaluates the crash sensors, decides in the event of an accident within milliseconds on the deployment of airbags and seatbelt pretensioners, and monitors the system continuously. After an accident, it stores crash data and locks itself.

The unit reports faults in the system via the airbag warning light in the instrument cluster. The crash data stays stored in the unit until it is deleted. The unit works in the background throughout every journey.

Why does the control unit 1390300080 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot delete it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

• aged electronic components
• cold solder joints on the circuit board
• moisture and corrosion at plugs
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 1390300080 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message also appears in the instrument cluster. The diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared. Then the airbags and seatbelt pretensioners may not deploy in an emergency.

Have the system checked promptly if these signs appear. Also note when the light comes on, as this information helps with troubleshooting.
