Airbag control unit Fiat 500 was broken. Hard to believe but they can really repair it! Recommendation!!
Automatically translated · Original: German
From the first phone call, the order processing, to the shipping, everything was done very quickly and professionally. Now I still have to send the repaired unit to the Swedish workshop and then hopefully the Honda can finally pass the HU there again (failed because of the red airbag light). Thanks to Airbag 24 in Berlin 👍👏. Gerd

What is an Aston Martin Cygnet airbag control unit?
In the Aston Martin Cygnet, the airbag control unit is the central control unit of the restraint system (SRS): it processes the readings from the crash sensors and, in an emergency, decides within milliseconds which airbags and seatbelt pretensioners fire. At the same time, it continuously monitors the entire system and indicates faults via the airbag warning light.
The unit is installed in the Aston Martin Cygnet (2011 to 2013) and was supplied by Denso. It runs in the background while you drive; only when it detects an irregularity does the warning light come on in the instrument cluster to alert you.
If an accident occurs, the control unit stores crash data and then locks itself. At the latest then, the airbag warning light becomes visible to you.
Why is the Aston Martin Cygnet airbag control unit defective?
An accident is the most common cause: the crash data stored in the unit remain even if no airbag was deployed and cannot be erased with an ordinary diagnostic tool. Other causes include aged electronic components, cold solder joints, moisture and corrosion on connectors, and voltage spikes.
Because the control unit stores crash data even when the accident did not trigger a deployment, the fault remains although everything seems fine on the outside of the vehicle. An attempt to erase it with the usual workshop equipment therefore leads nowhere.
The unit can also fail without an accident. Electronic components become less reliable over the years, solder joints turn cold and break the contact, and moisture and corrosion attack the wiring at the connectors. On top of that come voltage spikes, as can occur with a weak battery or when jump-starting.
A defect usually shows itself like this: the airbag warning light stays on permanently, the fault memory cannot be reset, or the diagnostic tool cannot establish a connection to the control unit at all.
Common error codes for Aston Martin Cygnet airbag control unit repair
The codes that occur with this control unit relate to internal faults of the unit, disrupted communication with other control units, the power supply, the squib circuits of the airbags, and stored crash data.
Fault codes are read out with a diagnostic tool that queries the fault memory of the control unit. Below you will find codes that are known for this vehicle, each with its meaning.
- 0131 → Internal component fault, initialisation failed
- CFFF → Internal fault of the restraint system control unit
- 013B → Multiple crash events stored in the crash memory
- 0128 → Vehicle configuration signal via CAN bus failed
- 0005 → Battery voltage too low
- 0006 → Battery voltage too high
- 0156 → Supply voltage between modules deviates
- 0013 → Driver airbag squib circuit: resistance too high
A single code does not yet prove that the control unit itself is defective, since connectors, wiring or an airbag module can just as well cause the entry. The cause only becomes clear during inspection.
What part numbers are available for the Aston Martin Cygnet airbag control unit repair?
On the label of the control unit you will find the part number, which defines the exact version. Depending on equipment and year of manufacture, the numbers differ even within one model series.
Known numbers for the Aston Martin Cygnet are listed below; the list may not be complete.
- 89170-74030 (Denso)
- 89170-74040 (Denso)
- 89170-74130
- 89170-74140 (Denso)
Compare the number on your own unit with this list. This merely ensures that you have the right unit in front of you; whether it actually has a fault is only shown by reading out the fault memory or by the inspection at Airbag24.
The route to repair looks like this: have the fault memory read out, disconnect the battery and remove the control unit. Then you create a repair order online and send the unit to Airbag24. Inspecting, repairing and testing usually take 3–4 working days there. 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.
