Airbag control unit with part number 01358990080

What is the function of the airbag control unit 01358990080?

The airbag control unit with part number 01358990080 is the central control module for the occupant protection system, primarily installed in the Fiat Ducato 250 and Opel Movano 250. It processes signals from crash sensors to precisely deploy airbags and seatbelt pretensioners in the event of a collision and stores relevant accident data in its internal memory.

As the brain of the passive safety system, this module decides within milliseconds whether to activate the restraint systems. It continuously monitors all connected components—such as sensors, airbag modules, and seatbelt pretensioners—for proper functionality. Depending on the production batch and year of manufacture, the device may be manufactured by Bosch, Delphi, or TRW.

After activation, the control unit stores so‑called crash data. This information locks the system to prevent unintended re‑activation and requires a vehicle inspection.

Why does the airbag control unit 01358990080 fail?

The most common cause of failure for control unit 01358990080 is the storage of crash data after an accident, which results in permanent lockout. Other causes include internal electronic malfunctions, moisture damage due to water ingress in the footwell, poor ground connections, or issues with the vehicle’s electrical system voltage.

Even after a minor collision, the control unit becomes locked, and error code B0100 (internal ECU fault) is stored in memory. This entry cannot be cleared using standard diagnostic tools and requires specialized repair involving resetting the memory chip.

Electronic components inside the unit can fail due to aging or voltage fluctuations, such as those occurring during jump-starts or battery problems. Another critical factor is moisture, which leads to corrosion on the circuit board and short circuits. Poor grounding at the housing can also cause malfunctions.

This control unit is also known under alternative part numbers 01370978080, 1370978080, 01371008080, and 1358992080, which are often technically identical or interchangeable.

How do you recognize a defect in control unit 01358990080?

A defect in control unit 01358990080 typically manifests as a permanently illuminated or flickering airbag warning light on the dashboard. Communication with diagnostic equipment may become impossible, or unerasable error codes such as B0100 (internal fault) or B0102-00 (ground fault) are recorded. Display messages like “Airbags defective” are also common.

The most obvious symptom is the active airbag warning light, signaling a fault in the restraint system and resulting in failure during the mandatory technical inspection. Sometimes the light only glows faintly, which likewise indicates an internal malfunction.

Another clear sign is when the control unit becomes unresponsive via the OBD interface. The workshop can no longer read fault codes or communicate with the module. Additionally, the onboard computer may display error messages such as “Airbags defective” or, specific to certain vehicles, “Fuel shut-off valve.”

Often, error code B0100 is stored, indicating blockage caused by crash data. Code B0102-00 specifically points to a missing ground connection at the housing, while errors like B1000, B1001, or B101C suggest general hardware or communication issues.

A rare but distinctive symptom in these models is a dashboard light that activates spontaneously when the vehicle is locked, suggesting an internal short circuit within the control unit.

In which vehicles is control unit 01358990080 installed?

The airbag control unit 01358990080 is installed in various van models from Fiat and Opel. At Airbag24, we repair this control unit for the Fiat Ducato and Opel Movano of the 250 series and C series, including all facelifts from 2006 to the present, where it serves as a central component of their safety system.

At Airbag24, we offer repair services for the control unit with part number 01358990080 for the following specific models and series:

Fiat: Ducato (from model year 2006 onward)

Opel: Movano 250 (2006–2011), Movano 250 1st facelift (2011–2014), Movano 250 2nd facelift (2014–2024), Movano 250 3rd facelift (from 2023), as well as Movano C (from 2021 onward)

How does the repair of control unit 01358990080 proceed?

At Airbag24, the repair of control unit 01358990080 begins with a precise incoming inspection and diagnosis upon submission. Depending on the nature of the defect, stored crash data is erased, faulty electronic components are replaced, or the unit is dried out if damaged by water. The repair restores the original functionality and includes 2 years’ statutory liability for defects.

The process begins with the professional removal of the control unit from the vehicle. We recommend having a fault log read out beforehand and including it with the package to expedite diagnosis.

Once the unit has been received at Airbag24, our technicians perform a comprehensive analysis. Depending on the nature of the fault, crash data is erased from the internal memory (EEPROM), defective components such as processors or capacitors are replaced, and cold solder joints are reworked.

Following repair, a thorough functional test is conducted on a test bench to ensure that all functions of the control unit are fully restored. We provide 2 years' statutory liability for defects on every repair performed.
