Airbag control unit with part number 01394326080

What does the airbag control unit 01394326080 do?

The airbag control unit 01394326080 works as the central control unit of the SRS for Fiat and Opel. It processes the sensor signals, selects in an accident the appropriate airbags and seatbelt pretensioners, and monitors the system continuously. It shows faults via the airbag warning light.

The control unit makes the triggering decision in a very short time. For that reason it checks the sensors and connections in the background, without you noticing anything.

After an accident the unit stores crash data and locks itself. This text gives no further details on the lock; causes and the repair process are covered in the following sections.

Why does the control unit 01394326080 fail?

The most common cause is stored crash data after an accident, which cannot be erased with a normal diagnostic tool. Other causes are aged components, cold solder joints, moisture and corrosion on plug connections, and voltage peaks.

Crash data is created even if no airbag was triggered in the accident. Airbag24 erases it during the repair.

The other causes are general in nature. Electronics age, solder joints can be cold, and moisture or corrosion affect the contacts on connectors.

Voltage peaks, for example from a weak battery or a jump start, also stress the electronics. Which cause applies is shown by the check.

How can you tell that the 01394326080 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. In addition, an error message appears in the instrument cluster, and the diagnostic tool finds no connection to the control unit; the fault memory also cannot be cleared. Airbags and seatbelt pretensioners may then fail to trigger in an emergency.

The light reports the defect so that you can act. It is no cosmetic fault but a warning from the restraint system.

When the light comes on, have the fault memory read out and record the findings before you plan any further steps.
