What is a Peugeot 605 I airbag control unit?
The Peugeot 605 I airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle. This essential component is vital for the safety of the vehicle's occupants.
It acts as the brain of the passive safety system and is responsible for the precise control of airbag deployment and seat belt pretensioners in the event of a collision.
The module receives signals from impact sensors and processes them to quickly ignite the pyrotechnic units if necessary.
It is constantly active and performs self-diagnosis of the entire airbag system to immediately detect and report malfunctions.
Why is the Peugeot 605 I airbag control unit defective?
The Peugeot 605 I airbag control unit often fails because it stores irretrievable crash data after an accident, or internal memory and communication errors can occur. These problems cause the airbag warning light to remain permanently illuminated, limiting the safety system's operational readiness and necessitating repair or replacement.
A common reason for failure is the storage of so-called crash data after an impact. This data is permanently stored in the control unit and prevents reuse, even in minor accidents.
Internal memory errors, often referred to as EEPROM errors, can prevent the control unit from performing its basic functions.
Communication problems between the control unit and the diagnostic device or other vehicle modules are also typical signs of a defective airbag control unit.
Electronic defects caused by aging, moisture or overvoltage can also contribute to the need for a Peugeot 605 I airbag control unit repair.
Common error codes for Peugeot 605 I airbag control unit repair
Typical error codes for the Peugeot 605 I airbag control unit indicate internal defects or communication problems with the module itself, not with sensors or other components. They signal the need for specialized diagnostics to identify the exact cause of the malfunction and perform a targeted Peugeot 605 I airbag control unit repair.
These code-specific errors directly indicate a problem within the airbag ECU.
- B1000 → Control unit communication error → Error in communication with the airbag ECU
- B1100 → Internal memory error → Defect in the EEPROM or internal memory of the airbag control unit
- B1210 → Self-diagnosis error of the airbag control unit → Internal self-test error in the airbag control unit
- B1333 → Internal error in the airbag control unit → General, non-sensor-related error in the control unit
- B1400 → Crash data saved, cannot be deleted → Crash data saved after an accident block the function
The workshop can read these error codes using a specialized diagnostic device and initiate the necessary steps for repair or replacement.
What part numbers are available for the Peugeot 605 I airbag control unit repair?
When repairing the Peugeot 605 I airbag control unit, precise OEM part numbers are crucial to ensure compatibility and functionality. Only verified numbers ensure that the replacement or repair part interacts correctly with the vehicle system and restores the airbag system's full safety performance.
For the original airbag control unit of the Peugeot 605 I, part number 96 287 574 80 is known as the verified OEM number from Peugeot/PSA.
This number is often mentioned in connection with airbag module reset services, which indicates the control unit itself.
Another relevant OEM part number is 6598X4 , which represents the airbag wiring harness as part of the overall system.
Both numbers are listed in professional sources for the Peugeot 605 I and are crucial for a successful Peugeot 605 I airbag control unit repair.
It is important that only these tested part numbers are considered when purchasing or repairing to avoid malfunctions or incompatibilities.
