Aston Martin DB11 airbag control unit repair⁽¹⁾

What should be considered with Aston Martin DB11 airbag control units?

The airbag control unit in the Aston Martin DB11 evaluates the crash sensors, triggers the airbags and belt tensioners, and monitors the entire restraint system. If it detects a fault, it reports it via the airbag warning light.

After an accident, the control unit stores crash data and locks itself. In the event of a defect or after a deployment, it should therefore be checked by a specialist workshop.

Airbag24 repairs the control unit from your own vehicle once it has been sent in.

Which Aston Martin DB11 generations are there?

The Aston Martin DB11 was built in a single series, the VH2 range, from 2016 to 2023. Within this series, equipment and engine options vary by variant.

• VH2 (2016–2023) – built as a coupé and as a Volante (convertible)

The DB11 was unveiled at the Geneva Motor Show in 2016. It was built until 2023, with a model update and additional variants during that time.

The exact variant can be identified by the model year and the vehicle identification number (VIN). These details matter, because control unit versions can also differ within a single series.

How do I identify my Aston Martin DB11 airbag control unit?

The part number on the control unit's label determines the exact version. Also check the model year and equipment of your vehicle before sending in a unit.

Known part numbers for the VH2 series, without any claim to completeness:

• HY53-14C246-AC
• 97128002
• 97128004

The part number HY53-14C246-AD is also known. Examples of fault codes in this series include 013B (three crash events stored in the crash memory), 0013 (resistance too high in the driver airbag firing circuit, stage 1) and 0005 (battery voltage too low). A single fault code does not by itself prove a defect in the control unit; an inspection establishes the cause.

What airbag equipment does the Aston Martin DB11 have?

The Aston Martin DB11 comes with several airbag modules as standard, including front airbags, side airbags in the front seats, and head or curtain airbags. Which modules are fitted exactly depends on model year and equipment.

The front airbags are intended for driver and front passenger. Side and curtain airbags only deploy on the side that was struck in an impact. According to the available information, knee airbags are fitted only in some versions of the DB11. The control unit coordinates all of these modules.

The route to repair: first have the fault memory read out. The battery is then disconnected before removal, and removal should be left to a specialist workshop. Next, create a repair order online and send the control unit to Airbag24. Processing usually takes 3–4 working days: the unit is inspected, repaired and tested.

The repaired control unit comes back with all vehicle data and is ready for immediate use after reinstallation — coding or programming is not necessary.
