Airbag control unit with part number 5801330269-AA

What is the function of the airbag control unit 5801330269-AA?

The airbag control unit 5801330269-AA, also known as the SRS control unit, is the central control module for the vehicle’s occupant protection system. It was manufactured by supplier Autoliv and is responsible for monitoring all relevant sensors and triggering the airbags and seatbelt pretensioners promptly in the event of a crash.

As the “brain” of the safety system, this module continuously processes data from the acceleration and yaw rate sensors. When it detects a collision exceeding predefined thresholds, it sends ignition signals to the appropriate restraint devices within milliseconds.

In addition, the control unit performs a self-test at every vehicle start-up and continuously monitors the functionality of all connected components, such as ignition circuits, sensors, and internal electronics. A detected fault is indicated by the illumination of the airbag warning light.

Why does the control unit 5801330269-AA fail?

The most common causes of failure for the control unit 5801330269-AA are stored crash data following an accident, which locks the unit, as well as internal hardware defects on the circuit board. These often result in the persistent error code B1000 “Control unit defective” and may require repair.

After a collision in which airbags or seatbelt pretensioners have deployed, the control unit irrevocably stores so‑called crash data in its internal memory (EEPROM/Flash). This electronic lock prevents further use for safety reasons and can only be lifted through specialized reprogramming.

Another frequent cause is an internal electronic defect. Components such as voltage regulators, microcontrollers, or memory chips may fail, typically manifesting as the error code B1000. Cold solder joints caused by vibrations and thermal cycling can also lead to intermittent or permanent malfunctions.

The part numbers 5801460860 and 620531800B are cross-references and may be installed in the same vehicles. They often exhibit identical fault patterns and are likewise repairable.

How do you recognize a defect in the 5801330269-AA?

A defect in the airbag control unit 5801330269-AA primarily manifests as a permanently illuminated airbag or SRS warning light on the instrument cluster. The error code B1000 “Control unit defective” is frequently logged in the fault memory, and communication with a diagnostic tool becomes impossible.

The clearest indication is the active airbag warning light that fails to extinguish after engine start-up. This signals a malfunction in the safety system, potentially preventing airbags from deploying in the event of a crash. An immediate inspection at a specialized workshop is therefore essential.

When reading the fault memory, the specific error code B1000 is often displayed. This code directly points to an internal, irreparable fault in the control unit that cannot be resolved simply by clearing the error.

Another clear symptom is when the control unit becomes unreachable via the diagnostic interface (OBD). The workshop then cannot establish a connection to read faults or check system parameters.

In rarer cases, the airbag light may also illuminate with a delay of 20 to 30 seconds after engine start-up, indicating an emerging defect in the control unit.

In which vehicles is the 5801330269-AA installed?

The airbag control unit with part number 5801330269-AA is mainly used in Iveco vehicles. It is particularly found in various generations and variants of the Iveco Daily van, where it manages the occupant protection system.

At Airbag24, we repair this control unit for the following specific models:

Iveco Daily II

Iveco Daily VII (from model year 2019 onward)

Iveco Daily Van VII

How does the repair of the 5801330269-AA proceed at Airbag24?

The repair of the control unit 5801330269-AA at Airbag24 includes a detailed analysis, targeted elimination of the root cause of the fault, and a final functional test. Depending on the nature of the defect, internal components are replaced or stored crash data is professionally erased to restore full functionality.

Upon receipt of the control unit, our technicians perform a comprehensive diagnosis. The fault memory is read to verify reported errors, such as B1000, and to check for the presence of crash data.

If an electronic defect is identified, the circuit board is repaired at the component level. Faulty parts—such as power supply modules, memory chips, or microcontrollers—are pinpointed and replaced with new, high-quality components. Cold solder joints are professionally reworked.

If crash data is the cause, it is safely erased from the control unit’s memory using specialized programming tools. This restores the module to its factory‑new (“Virgin State”) condition, making it fully operational again.

Finally, each repaired control unit is tested on a test bench. Here, all functions—including communication and ignition‑circuit monitoring—are simulated to ensure flawless performance comparable to that of a new part. You receive a 12‑month warranty on the repair.
