What is a Peugeot 604 I airbag control unit?
The Peugeot 604 I airbag control unit is the central safety unit that precisely activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of a collision. It continuously monitors sensors, stores important crash data, and ensures the proper functioning of the entire passive safety system in your vehicle.
This electronic control unit continuously processes signals from acceleration sensors in the vehicle. Based on this data, the control unit decides in milliseconds whether airbag deployment is necessary.
It is also responsible for self-diagnosis of the airbag system, stores error codes and communicates with other vehicle-specific bus systems to ensure safety.
Why is the Peugeot 604 I airbag control unit defective?
A Peugeot 604 I airbag control unit often fails because it develops internal component errors, irretrievably stores crash data after an accident, or fails due to power supply problems. The system can then no longer communicate correctly or fails to trigger the safety functions in an emergency.
Typical defects include a loss of internal communication or an error message that cannot be cleared. Such problems often lead to a defect in the Peugeot 604 I airbag control unit.
An interruption in the power supply or an irreversible crash entry after an accident can also render the control unit unusable, making repair or a reset necessary.
