Works like a charm!
Everything went perfectly, I can only recommend it.

From the first phone call, the order processing, to the shipping everything was done very quickly and professionally. Now I still have to send the repaired unit to the Swedish workshop and then hopefully the Honda can finally pass the HU there again (failed because of the red light for the airbag). Today the message came from SWE, the car is running again, the red light is off and the HU was also passed. Once again many thanks for the help in need. Keep it up and maybe word will also spread in SWE that Airbag 24 does great work. Regards Gerd

What is a Peugeot 508 II airbag control unit?
The Peugeot 508 II airbag control unit is the central safety unit in your vehicle, immediately activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors relevant sensors, stores important crash data, and ensures the proper functioning of the entire passive safety system to provide optimal occupant protection.
This electronic module processes signals from acceleration and yaw rate sensors to assess the severity and type of impact.
It is designed for a fast response time and, if necessary, also initiates emergency calls (eCall), even if no airbags have been deployed.
Why is the Peugeot 508 II airbag control unit defective?
The Peugeot 508 II airbag control unit is often defective because it stores crash data after an accident, internal electronic components can fail, or it can be damaged by water damage or overvoltage. A defective module can completely impair the functionality of the airbags, which poses a serious risk to vehicle safety.
After an accident, the control unit often blocks by storing crash data (e.g. error code B1649), which makes a reset or repair unavoidable.
Internal errors in the memory or communication logic (e.g. B1003, B1401) are also common causes of failure or malfunction of the airbag control unit.
A professional Peugeot 508 II airbag control unit repair is necessary to correct these errors and restore full functionality.
Common error codes for Peugeot 508 II airbag control unit repair
During a Peugeot 508 II airbag control unit repair, specific B-codes may occur that directly indicate internal module errors, communication problems, or stored accident data, making diagnosis and repair essential. These codes clearly indicate that the control unit itself is affected, not just peripheral sensors.
- B1000 → Control unit communication error → Signal disturbance within the airbag module.
- B1003 → Internal memory error / EEPROM error → Defect in the non-volatile memory of the control unit.
- B1015 → Faulty airbag control unit module → A general malfunction of the airbag ECU.
- B1139 → Error within the SRS control unit → An internal malfunction in the supplemental restraint system.
- B1193 → Airbag module related error → Direct error originating from the airbag control unit itself.
- B1206 → Airbag RCM (Restraint Control Module) Error → Problem in the restraint module, the central control.
- B1342 → SRS system error → A general error in the entire Supplementary Restraint System.
- B1401 → Memory error in the control unit → Defective memory cells in the airbag control unit.
- B1620 → SRS Error → Safety restraint system system error.
- B1649 → Accident detected (Crash Data saved) → Module is blocked after an impact and requires a reset.

Technical characteristics and compatibility of the Peugeot 508 II airbag control unit
The Peugeot 508 II airbag control unit acts as the core of the passive safety system and is specifically designed for 12-volt electrical systems. It communicates with all crash sensors and deploys the airbags when necessary. It is compatible with all Peugeot 508 II sedan and station wagon (SW) variants produced from 2018 onwards, regardless of engine or equipment.
It is connected directly to the vehicle's electrical system (12 volts) and to the safety components via special, yellow-marked connectors with gold-plated pins.
The control unit continuously monitors its own functions and those of the connected sensors in order to report errors via the instrument cluster or diagnostic interfaces.
The control unit's software is optimized for fast response times and high reliability, which is essential for safety.
A professional Peugeot 508 II airbag control unit repair ensures the restoration of these critical safety functions.
