B1413-00 - Crash (crash data stored) airbag control unit fault

What does error code B1413-00 mean?

Error code B1413-00 indicates that crash data has been permanently stored in the airbag control unit’s memory. This condition occurs after an accident or a severe impact, causing the control unit to lock itself for safety reasons. All relevant crash data is recorded, preventing reactivation of the airbag system until the data is professionally erased.

The airbag control unit is the central control module of the passive safety system. Its primary function is to process signals from crash sensors to detect a collision and determine the optimal timing for deploying the airbags. An integrated ignition capacitor ensures power supply independent of the vehicle battery.

An important feature is assessing crash severity on a scale from 0 to 3. In cases of low severity (level 0), the impact is registered and logged, but the airbags are not deployed. Even in such situations, error code B1413-00 is set, and the warning light illuminates.

Storing crash data serves as a self-protection mechanism. Once the airbags have deployed or a severe impact has been detected, the module locks itself to prevent any unintended or erroneous activation in the future. The system assumes an unsafe situation until a reset is performed.

What symptoms indicate B1413-00?

The main symptom of error code B1413-00 is the continuously illuminated airbag warning light on the instrument panel. Additionally, the fault memory cannot be cleared using standard diagnostic tools. In some cases, communication with the control unit is completely blocked, or additional software and communication errors appear.

The airbag warning light is the most obvious sign. It remains lit after starting the vehicle, indicating that the entire airbag system is disabled and will not function in the event of another accident.

A diagnosis at a workshop reveals that error code B1413-00 is marked as permanent or non‑erasable. Standard attempts to clear it via the OBD interface fail because the data is deeply embedded in the control unit’s memory.

Furthermore, additional fault messages may be stored, pointing to communication issues or problems with the control unit’s coding. These are direct consequences of the locked state the module enters following a crash.

What causes B1413-00?

The sole and direct cause of error code B1413-00 is the registration of a crash event by the airbag control unit, which occurs after a severe impact. While the crash itself triggers the code, secondary issues—such as water damage, faulty wiring, or defective sensors—can complicate repairs and prevent a simple reset.

The trigger is always a physical event that exceeds the predefined thresholds of the crash sensors. The control unit then permanently stores the relevant data in its internal memory to document the incident.

During fault diagnosis, a visual inspection of surrounding components is performed first. Common sources of failure include damaged connectors beneath the seats—especially in three-door models due to seat movement—or a compromised coil spring on the steering wheel, which is stressed with every steering motion.

In some cases, simply erasing the crash data is insufficient. This happens when additional hardware defects are present, such as moisture inside the control unit leading to short circuits, or faulty circuit boards and memory chips that continue to impede proper functionality even after a reset.

Which vehicles are affected by B1413-00?

Error code B1413-00 is manufacturer‑independent and generally affects all modern vehicles equipped with electronic airbag systems that store crash data. At Airbag24, we have successfully diagnosed and repaired this issue across various models, particularly those from Peugeot.

Specifically, we can offer repair services for the following models we service:

Peugeot: 308 III (model years 2021–2025) and the upcoming third‑generation facelift (from 2025 onward).

Storing crash data is a standard procedure in vehicle safety management. Therefore, specialized workshops provide repair solutions for numerous manufacturers, including Audi, BMW, Mercedes-Benz, Volkswagen, Ford, Opel, Toyota, and many others.

How does repair work at Airbag24?

When repairing error code B1413-00 at Airbag24, the stored crash data is removed from the control unit’s memory using specialized equipment. After receiving the removed unit, it is restored to factory settings. The repair restores full functionality and typically does not require re‑coding. We offer 2 years' statutory liability for defects on all repairs.

The process begins with removing the airbag control unit from the vehicle. You then send the unit to us along with a completed repair order. Before removal, the fault memory should be read out to confirm the error code.

Upon receipt at Airbag24, the control unit undergoes a thorough analysis. Our technicians electronically erase the crash data and resolve any software errors that may be present. This process restores the module to its original factory condition.

Next, the full functionality of the unit is tested. A major advantage of this repair is that, after installation, the control unit operates in “plug-and-play” mode. Extensive coding or re-learning procedures for the vehicle are unnecessary.

Following successful repair and final testing, the control unit is promptly returned to you. Every repair performed is covered by our 2 years’ statutory liability for defects, ensuring peace of mind and reliable operation of your airbag system.
