Aston Martin DB7 airbag control unit repair⁽¹⁾

What should I pay attention to with Aston Martin DB7 airbag control units?

The airbag control unit in the Aston Martin DB7 evaluates the crash sensors, triggers the airbags and belt pretensioners, and monitors the entire airbag system. Airbag24 repairs the customer's own control unit that has been sent in.

After an accident, the control unit stores crash data and locks itself. A defective control unit can impair the function of the entire airbag system and switch on the airbag warning light.

The airbag system is safety-relevant. Work on it should be left to a specialist workshop; do not work on the system yourself.

Which Aston Martin DB7 generations are there?

The Aston Martin DB7 belongs to the Mk1 series and was built from 1994 to 2003.

• Mk1 (1994–2003) – series of the Aston Martin DB7

Whether your vehicle belongs to the Mk1 series can be seen from its model year. Within the production period, control units and equipment can differ by model year and specification, which is why an exact assignment matters.

How do I identify my Aston Martin DB7 airbag control unit?

The part number on the label of the control unit determines the exact version. Together with the model year and equipment of your vehicle, it narrows down the right control unit.

The following part numbers are recorded for the Aston Martin DB7:

• 37120593 AC
• LNA2278AA

This list does not claim to be complete. Fault codes help with classification but do not by themselves prove a defect. Three examples from the codes recorded for the DB7 are: 0132 (internal component fault, start of VOODOO failed), 013B (three crash events stored in the crash memory) and 0005 (battery voltage too low).

For a vehicle of this age, it is worth checking the model year, part number and equipment together before a control unit is sent in.

What airbag equipment does the Aston Martin DB7 have?

Front airbags for driver and front passenger are documented for the Aston Martin DB7. Which further airbags are fitted depends on the model year and equipment.

The documentation of the DB7 airbag system describes airbag modules for driver and passenger, two front crash sensors and a safing sensor. The system is designed to protect driver and front passenger in a frontal collision. Side or head airbags are not documented for the DB7 and are therefore not listed here as equipment.

The vehicle documents and the vehicle identification number (VIN) help to clarify the actual equipment.

This is how you get to the repair:

• Have the fault memory read out so that the fault codes are documented.
• Have the battery disconnected and the control unit removed; ideally a specialist workshop does this.
• Create a repair order online with Airbag24.
• Send the control unit in, well packed. Processing usually takes 3–4 working days (checking, repairing, testing).

The repair is carried out in our workshop in Berlin. The repaired control unit is returned with all vehicle data and is ready for use immediately after refitting — no coding or programming is required.
