The Saab 9-5 TurboEdition airbag control unit, also known as the SRS SDM, is the central control unit for your vehicle's safety systems. It continuously monitors all airbag and seatbelt pretensioner sensors, detects accidents, and instantly deploys the passive restraint systems in an emergency to provide optimal occupant protection.
This safety-critical module is designed for Saab 9-5 TurboEdition models built between 1998 and 2009. It ensures the reliable function of the airbags in sedan and station wagon models with 2.0L and 2.3L turbo engines.
Its main task is to process data from crash and impact sensors. Based on this information, the control unit decides whether and when to deploy the airbags and seatbelt pretensioners.
Why is the Saab 9-5 TurboEdition airbag control unit defective?
A Saab 9-5 TurboEdition airbag control unit is often defective due to internal electronic malfunctions, power supply issues, or memory errors after an accident, making a "Saab 9-5 TurboEdition airbag control unit repair" essential. Such defects typically result in illuminated airbag warning lights and stored error codes.
Common causes include internal diagnostic errors or problems with the module's power supply. Memory errors can also occur, especially if crash data was not properly erased after an impact.
Communication errors in the CAN bus system or defects in the hardware and software of the control unit itself can also cause a failure. This often manifests itself as constant warning messages in the cockpit.
A repair is possible in many cases and is often more cost-effective than a replacement. Specially trained workshops can perform the necessary "Saab 9-5 TurboEdition airbag control unit repair."

- B1620 → Control unit self-test error → Critical error during the internal self-test of the module
What part numbers are available for the Saab 9-5 TurboEdition airbag control unit repair?
Unfortunately, there are no universally verified OEM part numbers publicly available for the "Saab 9-5 TurboEdition airbag control unit repair," as these are often vehicle-specific and tied to internal manufacturer databases. Precise identification usually requires reading directly from the component.
Official OEM part numbers for the airbag control unit of the Saab 9-5 TurboEdition are difficult to find in freely accessible databases such as TecDoc or manufacturer catalogs. This makes the search for suitable new parts considerably more difficult.
For precise identification, we recommend using the part number printed on the existing control unit. This part number is the most reliable reference for a successful Saab 9-5 TurboEdition airbag control unit repair or replacement.
Due to vehicle-specific programming and the link to the vehicle identification number (VIN), a simple replacement of used control units is often not possible. Professional reprogramming or a crash data reset is usually required.
