What is a Peugeot Expert II airbag control unit?
The Peugeot Expert II airbag control unit is the central safety unit in your vehicle, precisely activating 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 safety modules to provide the best possible occupant protection.
This electronic module is the brain of the passive safety system and crucial for occupant safety. It processes signals from impact sensors in milliseconds and triggers the appropriate protective measures when necessary.
In addition to airbag deployment, the control unit can also automatically send an emergency call when a collision is detected, even if no airbag has deployed. This ensures rapid assistance if you are no longer able to act.
Why is the Peugeot Expert II airbag control unit defective?
A defective Peugeot Expert II airbag control unit can have various causes. The most common are crash data being stored after an accident, internal electronic faults due to aging or overvoltage, and moisture damage. If the control unit is defective, the airbag warning light in the dashboard will usually illuminate continuously, signaling a malfunction and requiring urgent repair.
After an accident, the control unit stores crash data that prevents the airbags from deploying again. Even if no damage is visible, the module must be reset or replaced to restore full functionality.
Internal component failure, corrosion of connectors, or software errors can also lead to failure. A Peugeot Expert II airbag control unit repair is essential to ensure the safety of your vehicle.
Common error codes for Peugeot Expert II airbag control unit repair
