Volvo XC60 SPA airbag control unit repair

What is a Volvo XC60 Series 2 airbag control unit?

The Volvo XC60 Series 2 airbag control unit is the central safety unit (SRS) that activates all occupant restraint systems in the event of an accident. It precisely monitors sensors, stores relevant crash data, and ensures the immediate and proper deployment of all airbag modules and seatbelt pretensioners in the vehicle.

This multi-restraint control module (RCM) processes important information from various vehicle sensors, coordinating the life-saving deployment of airbags and other safety systems in an emergency.

The control unit is compatible with all Volvo XC60 models from approximately 2009 to 2017. It is suitable for various trim levels and engines, such as the D5244T10 diesel engine.

Why is the Volvo XC60 Series 2 airbag control unit defective?

A Volvo XC60 Series 2 airbag control unit often fails because it stores crash data after an accident that needs to be erased, or because of internal electronic errors such as overvoltage. A faulty configuration or communication problems in the vehicle network can also cause a failure.

Because the control unit stores important crash data after an accident, this can lead to a permanently illuminated airbag warning light, even if there is no visible damage. This data must be professionally erased before the vehicle is put back into operation.

Internal faults, such as a power supply defect (U200B) or general internal control unit damage (U3000), can damage the module. Such failures often require specialized repair or replacement of the device.

Communication problems in the vehicle bus (SRS-00D5, SRS-U014000) or incorrect programming (SRS-00D0) can also cause the airbag control unit to malfunction. These problems require a precise diagnosis and may require a targeted repair.

Common error codes for Volvo XC60 Series 2 airbag control unit repair

When diagnosing a faulty Volvo XC60 Series 2 airbag control unit, specific trouble codes are crucial for identifying the exact cause of the failure. These codes directly indicate problems with the control unit's configuration, communication, or internal functions and are essential for a successful repair.

• SRS-00D0 → Control unit incorrect configuration → Often incorrectly programmed after replacement or software problems.
• SRS-00D5 → Communication error with SRS control unit → Problems in the vehicle bus (CAN/LIN), such as cable defects or module failure.
• SRS-U014000 → Loss of communication with central module → Loss of communication with the Central Electronic Module via the vehicle network.
• U200B → Control unit voltage supply error → Internal error source in the voltage supply of the airbag ECU.
• U3000 → Control unit faulty → Generic control unit damage or software error in the airbag control unit itself.

What part numbers are available for the Volvo XC60 Series 2 airbag control unit repair?

For a successful Volvo XC60 Series 2 airbag control unit repair, identifying the correct part number is crucial, as compatibility is vehicle-specific. There are several original and OEM part numbers that have been verified to work specifically with the Volvo XC60 Series 2 airbag control unit, allowing for precise matching.

Commonly used genuine Volvo part numbers include P31318792 and 31318792. These have been confirmed multiple times and are suitable for the XC60 Series 2 across all models, especially those built between 2009 and 2017.

Another important OEM number is P31406637, which is often found in conjunction with the Bosch original part number 0285012268. Bosch is a leading supplier of airbag components and confirms OEM quality.

For specific variants of the XC60 Series 2, the Volvo OEM number 31295241 (e.g., for 3.2 AWD petrol engines) and the newer variant P32315584 (for 2021 models) are also relevant. Checking the vehicle identification number (VIN) is always recommended to ensure the exact compatibility of the airbag control unit for your specific Volvo XC60 repair.
