Airbag control unit with part number 01357312080

What is the function of Airbag Control Unit 01357312080?

The airbag control unit with part number 01357312080 is the central control unit (SRS ECU) for the occupant protection system in vehicles such as the Peugeot Boxer, Citroën Jumper, Fiat Ducato, and Opel Movano. It receives data from crash sensors, processes it in real time, and activates the necessary restraint systems—such as airbags and seatbelt pretensioners—in the event of a collision.

As the “brain” of the safety system, it continuously monitors all connected components, from impact sensors to individual airbag modules and seatbelt pretensioners. In the event of a collision, the unit determines within milliseconds which safety devices need to be activated to provide optimal protection for occupants.

Why does control unit 01357312080 fail?

The most common cause of failure for control unit 01357312080 is the storage of crash data after an accident that cannot be erased via the OBD2 interface. Other causes include internal electronic malfunctions leading to communication failures, or faulty signals from connected components such as the seatbelt buckle switch (error B101C).

Following a crash, so‑called crash data is stored in the control unit’s memory, which the system locks for safety reasons. This condition is often indicated by error code 65 3 550 and can only be reset through specialized chip‑level repair.

Internal defects in the electronics can also result in total failure. This often manifests as the control unit becoming unreachable by diagnostic tools. External factors, such as cable breaks caused by corrosion in the Fiat Ducato, may falsely suggest a fault in the control unit.

Additional documented issues include a missing Vehicle Identification Number (VIN) in the device’s memory or a falsely activated indicator for the fuel shut‑off valve. Occasionally, units with similar part numbers like 1356791080 are affected by the same problems.

How do you recognize a defect in 01357312080?

A defective airbag control unit 01357312080 primarily shows itself through a permanently illuminated airbag or SRS warning light on the instrument panel. Often, the control unit can no longer be read by diagnostic equipment (no communication), or specific error codes such as 65 3 550 (crash data) or B101C (seatbelt buckle switch) appear.

The most obvious symptom is a continuously or intermittently lit airbag warning light, frequently accompanied by a message prompting you to consult the vehicle’s manual.

Another clear sign is complete loss of communication: the workshop cannot establish a connection between the diagnostic tool and the airbag control unit, making fault analysis via the OBD interface impossible.

In addition, specific malfunctions may occur, such as locked airbags or incorrect activation of the fuel shut‑off valve—even when there is no mechanical issue. These symptoms point to a deep‑seated internal fault within the control unit.

Important safety note: Any work on the airbag system must be performed exclusively by trained professionals. Improper interventions or the use of simulators are life‑threatening and will result in the revocation of the vehicle’s operating permit.

How does the repair of 01357312080 proceed at Airbag24?

At Airbag24, the repair of control unit 01357312080 begins with a professional initial inspection on a test bench. Subsequently, stored crash data is irreversibly deleted, and any internal electronic faults are rectified. Following successful final tests and quality control, the refurbished unit is returned with 2 years' statutory liability for defects.

First, a thorough diagnosis should be carried out at a specialized workshop to confirm that the fault truly lies within the control unit. After removal—the unit is often located beneath the right front edge—please send it to us securely packaged. Including a diagnostic report will expedite the process.

Upon arrival at Airbag24, our technicians perform a comprehensive analysis. The repair includes safely resetting the stored crash data and addressing any internal hardware faults. This process restores the device to full functionality.

Following successful repair and passing functional tests, the control unit is returned to you. After reinstalling it in your vehicle, you may need to clear the vehicle’s fault memory in some cases to extinguish the airbag warning light. We provide 2 years' statutory liability for defects on every repair.
