Airbag control unit with part number 9467160889

What is the function of the airbag control unit 9467160889?

The airbag control unit with part number 9467160889 is the central control unit (SRS/ACU) for the passive safety system in vehicles of the PSA/Stellantis group. It processes data from crash sensors and is responsible for precisely and rapidly deploying airbags and seatbelt pretensioners in the event of a collision.

As the “brain” of the restraint system, this control unit continuously monitors all connected components, including front and side airbags, pyrotechnic seatbelt pretensioners, and the vehicle’s crash and acceleration sensors.

Its primary task is to detect a collision and initiate the necessary safety measures to provide optimal protection for occupants. After deployment, the unit locks itself for safety reasons and must be professionally reset.

What defects occur in 9467160889?

The most common reason for repairing control unit 9467160889 is the storage of crash data in its internal memory (EEPROM/Flash) following an accident. In addition, internal electronic faults—recorded as “control unit defective” in the fault memory—or communication issues can also lead to failure.

After a collision, even if only one seatbelt pretensioner has been activated, so‑called “crash data” are stored in the control unit. This results in permanent locking of the unit, which cannot be cleared by workshop diagnostics and causes the airbag warning light to remain illuminated.

Another typical defect is internal hardware failure. Diagnostic tools may report error codes such as “Internal fault” or “ECU defective.” Common causes include faulty components on the circuit board, such as voltage regulators, memory chips, or microcontroller peripherals.

Rarely, communication errors on the CAN bus (U‑codes) or sporadic malfunctions due to improper power supply or corroded connectors may occur, mistakenly suggesting a defective control unit.

How do you recognize a defect in control unit 9467160889?

The clearest symptom of a defect in control unit 9467160889 is the permanently illuminated airbag warning light (SRS symbol) in the instrument cluster. Reading the fault memory typically reveals entries like “Crash data stored” or “Internal error,” which cannot be erased.

The red airbag warning light does not turn off after starting the vehicle and completing the self‑test. This indicates that the entire restraint system is disabled and will no longer provide protective functions in the event of another accident.

When diagnosed with a suitable tester, communication with the airbag control unit often fails, or specific error codes appear, directly pointing to an internal fault or lockout caused by crash data.

In which vehicles is control unit 9467160889 installed?

Airbag control unit 9467160889 is primarily used in commercial vehicles and vans from the PSA Group and later Stellantis. This includes models from Peugeot, Citroën, and Fiat, especially the Expert, Jumpy, and Scudo series across multiple generations.

At Airbag24, we repair control units with part number 9467160889 for the following models and series:

Citroën: Jumpy III (2016–2023), ë-Jumpy III

Fiat: Scudo 220 (1996–2006), Scudo 270 (2007–2016), E-Scudo 272

Peugeot: Expert II (2007–2012), Expert II Facelift (2012–2016)

For successful repair or replacement, it is crucial that the part number printed on the device matches exactly to ensure compatibility in terms of coding and pin configuration.

How does repair work at Airbag24?

After sending the removed control unit 9467160889 to Airbag24, technicians perform a detailed analysis. The repair process includes professionally erasing crash data or replacing defective electronic components. Following a successful test, the unit is returned with 2 years’ statutory liability for defects.

The process ideally begins with a professional diagnosis at the workshop to rule out peripheral faults and document the fault history. The control unit is then carefully removed and securely packaged for shipment to us.

At Airbag24, the unit first undergoes an incoming inspection. Specialized technicians read the internal memory chips (EEPROM/Flash) to remove crash data and restore the control unit to factory settings.

If an internal hardware defect is detected, repairs are carried out at the component level. Upon completion of the work and a functional test, the control unit is fully operational again. We provide 2 years' statutory liability for defects on every repair.
