What is a Peugeot e-Boxer IV airbag control unit?
The Peugeot e-Boxer IV airbag control unit is the central safety unit in the vehicle, which activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the proper functioning of all airbag modules.
This electronic control unit processes signals from impact sensors and decides on the necessary safety measures in milliseconds.
The control unit's software is specifically tailored to the vehicle. When repairing the Peugeot e-Boxer IV airbag control unit, all vehicle-specific data must be transferred.
Why is the Peugeot e-Boxer IV airbag control unit defective?
A Peugeot e-Boxer IV airbag control unit often malfunctions after an accident because it stores crash data that prevents reactivation without being reset. Internal electronic errors, overvoltages in the electrical system, or corrosion on the contacts can also lead to failure, necessitating a Peugeot e-Boxer IV airbag control unit repair.
After an accident, irreversible crash information is stored in the control unit, which blocks the system from further use.
Internal component failures or communication problems can also cause the airbag system to fail and the warning light on the dashboard to activate.
Sometimes the control unit is just "broken" in the sense of a stored blockage that can be repaired by specialist personnel.
Common error codes for Peugeot e-Boxer IV airbag control unit repair
During Peugeot e-Boxer IV airbag control unit repairs, specific error codes may occur that indicate internal malfunctions or communication issues and require a precise diagnosis. These codes are crucial for precisely identifying and correcting the airbag system failure.
- B0100: Airbag control unit malfunction → The control unit is reporting an internal error or there is no communication. → This is a typical failure or a crash data record saved after an accident results in "defective."
- B0101: Internal Control Unit Error → A component in the airbag control unit is damaged or the internal software is defective. → Requires in-depth diagnostics and may indicate a physical "broken" condition.
- B101C: Driver's Side Seat Belt Buckle Switch Error → The control module detects a malfunction or an implausible signal from the driver's side seat belt buckle switch. → An electrical fault affecting the control module that requires a precise diagnosis.
What part numbers are available for the Peugeot e-Boxer IV airbag control unit repair?
Several OEM part numbers are relevant for the Peugeot e-Boxer IV airbag control unit repair, ensuring compatibility with the platform, although none exist exclusively for the e-Boxer IV. The parts are technically related to those of the current Boxer IV diesel models and can be identified by specific Stellantis numbers.
The most commonly validated OEM part number for current Boxer/e-Boxer series is 01371009080 (Stellantis/PSA Original).
Alternatively, the numbers 01370978080 and 01388160080 are also known for the latest generations of the Boxer, Ducato and Jumper and may be suitable for a Peugeot e-Boxer IV airbag control unit repair.
Supplier numbers (e.g. from Bosch or Continental) are usually not listed in publicly accessible catalogs, since the vehicles are listed under the OEM number.
Functionality and features of the Peugeot e-Boxer IV airbag control unit
The airbag control unit in the Peugeot e-Boxer IV evaluates data from various sensors in real time to precisely deploy the airbags and seatbelt pretensioners within milliseconds in the event of an accident. After deployment, it stores all relevant crash data for accident analysis, and the warning light is activated.
The control unit contains sophisticated safety logic that prevents accidental deployment of the airbags, for example in the event of static discharge or minor shocks.
System errors or communication failures are immediately stored in the internal error memory, enabling rapid diagnosis.
Specialized services are available for Peugeot e-Boxer IV airbag control unit repair, including crash data deletion, cloning, and vehicle-specific data transfer.
Installation position and connections for the Peugeot e-Boxer IV airbag control unit repair
For safety reasons, the airbag control unit of the Peugeot e-Boxer IV is installed centrally in the vehicle, usually in the center console or under the dashboard, to ensure short and secure connections to all airbag sensors and actuators. Removal and installation may only be performed by qualified personnel.
It is connected via special, often bright yellow cables and connectors that ensure clear identification in the vehicle electrical system.
The connectors have gold-plated contacts to provide maximum reliability and corrosion protection for signal transmission.
Before performing any work on the airbag control unit or the airbag system, the battery cable must be disconnected to prevent accidental deployment.
Special features of the Peugeot e-Boxer IV airbag control unit
The Peugeot e-Boxer IV airbag control unit is specifically designed for the requirements of an electric vehicle, including compatibility with high-voltage systems and integration with modern advanced driver assistance systems (ADAS). This underscores the need for a professional Peugeot e-Boxer IV airbag control unit repair.
For the e-Boxer IV, the control unit is designed for high electrical load capacity in order to harmonize seamlessly with the high-voltage battery and the specific electrical systems of the electric vehicle.
There may be variants of the control unit that differ in terms of different software versions, the number of airbag loops or special interfaces for other vehicle systems.
Specialized workshops offer professional services to restore a defective control unit to functionality after an accident by deleting the crash data and conducting comprehensive tests.
