Airbag control unit with part number 00052211318

What does the airbag control unit 00052211318 do?

The airbag control unit 00052211318 is the central control unit of the restraint system (SRS) of Fiat. It evaluates the crash sensors, decides in a crash whether airbags and seatbelt pretensioners are triggered, and locks itself after an accident.

During operation the unit checks the connections to all triggers. If it detects a fault, the airbag warning light in the instrument cluster lights up and the fault is stored in the memory.

Why does the control unit 00052211318 fail?

The most common cause is stored crash data after an accident, even if no airbag has deployed. A standard diagnostic tool cannot erase it. Other causes include ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data remains in the memory. The fact that the airbags did not deploy changes nothing.

The other causes lie in the electronics. Components age, solder joints can go cold, and moisture or corrosion at plug connections disrupts signal transmission. Voltage spikes can also put a strain on the unit.

How can you tell that the 00052211318 is defective?

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

The signs at a glance:

• airbag warning light on permanently or intermittently
• error message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory cannot be cleared

How does the repair of the 00052211318 work?

First you read out the fault memory and enclose the log. Then you disconnect the battery and only afterwards remove the control unit. Next you create a repair order online and send in the carefully packed unit. Airbag24 checks the unit, replaces defective components and performs a function test; processing there takes 3–4 working days as a rule. With this control unit, erasing the crash data is often not possible. If the crash data needs to be erased, please contact us briefly before sending the unit in – we will check your part number.

The order of the first steps is binding, because the control unit may only be removed from the vehicle after the battery has been disconnected. Afterwards your own unit is returned to you.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
