What is a Volvo 460 Series 1 airbag control unit?
The Volvo 460 Series 1 airbag control unit is the central safety unit that activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors and stores relevant crash data, ensuring the proper functioning of the entire airbag system in the vehicle. It is a critical component for any Volvo 460 Series 1 airbag control unit repair.
This electronic module receives and processes signals from various crash sensors distributed throughout the vehicle.
Its main task is to trigger the protective systems in a fraction of a second in order to optimally protect the occupants.
Why is the Volvo 460 Series 1 airbag control unit defective?
A Volvo 460 Series 1 airbag control unit often fails because it permanently stores crash data after an accident, causing it to lock, or due to age-related electronic component failure and moisture damage. Such a failure requires immediate professional Volvo 460 Series 1 airbag control unit repair to restore the safety system's full functionality.
Because the control unit stores irreversible crash data in the event of an impact, it can be considered "broken" even after a minor accident and must either be replaced or specially reset.
Age-related fatigue of the solder joints or corrosion due to moisture penetration can also lead to module failure, requiring immediate repair or replacement.
Common error codes for Volvo 460 Series 1 airbag control unit repair
Specific trouble codes for the Volvo 460 Series 1 airbag control unit are rarely listed in detail in public databases, but general SRS codes indicate problems that require diagnosis and, if necessary, Volvo 460 Series 1 airbag control unit repair. These trouble codes signal malfunctions in the system and guide the workshop in troubleshooting.
While exact codes for the Volvo 460 Series 1 are difficult to find, the following general SRS trouble codes may indicate problems that require a comprehensive diagnosis:
- SRS-00D0 → Meaning: SRS Control Module Faulty Configuration → Cause: Incorrect programming of the module, software problems or internal defects that require repair or replacement.
- SRS-00D5 → Meaning: Communication Fault with SRS Control Module → Cause: A faulty control module itself, problems with the CAN bus cable or general network communication problems that signal a failure.
What part numbers are available for the Volvo 460 Series 1 airbag control unit repair?
For the Volvo 460 Series 1 airbag control unit repair, two precisely verified OEM part numbers are primarily relevant: the Bosch number 0285001049 and the Volvo original part number 474128. These numbers confirm the compatibility of the airbag control unit with your vehicle and are crucial for the correct selection of replacement parts.
The Bosch part number 0285001049 is an original OEM number that is listed in official Bosch catalogs as an airbag control unit for Volvo 460 models, especially the turbo diesel variant from around 1996 onwards.
The Volvo OEM number 474128 is the official Volvo genuine part number that uniquely identifies the control unit to the Volvo 460 Series 1 and is often used together with the Bosch number as a reference to troubleshoot a failure.
Installation position and technical data for the Volvo 460 Series 1 airbag control unit repair
The installation location of the Volvo 460 Series 1 airbag control unit is typically located in the center console, protected from external influences, which is important for an effective Volvo 460 Series 1 airbag control unit repair. It is technically tuned to the specific crash parameters of the 460 models to precisely trigger pyrotechnic airbags and seatbelt pretensioners.
The airbag control unit is usually mounted in the footwell of the center console or directly under the center console, which ensures a safe, protected installation location.
This control unit is specifically designed for Volvo 460 Series 1 vehicles from the 1990s, including sedans with petrol engines (e.g. 2.0i) and especially diesel versions such as the 1.9 Turbo-Diesel (D19T).
It continuously monitors the system using central and satellite-based sensors that detect crash events with millisecond accuracy and, in the event of an accident, control the deployment of the airbags and seat belt pretensioners.
The electrical connections include connections to front and side airbag modules, seat belt pretensioners, as well as sensor connections for acceleration sensors and a secured power supply from the vehicle battery, which is crucial for diagnostics and any workshop repair.
