Description
Bosch Airbag Control Unit For Peugeot 207. Fully Functional.
High-quality replacement Bosch airbag (SRS) control module designed for Peugeot 207. This unit is suitable for professional workshops and experienced DIY mechanics who need a reliable airbag ECU with original-equipment compatibility. Ideal when the original control unit has been triggered in a collision, shows internal fault codes, or has been damaged by moisture or electrical problems. Supplied unit can restore airbag system functionality when fitted and initialized correctly.
Technical Information
- Manufacturer: Bosch
- Model: Peugeot 207
- Product Codes: 9675068880, 0285010828
- Additional Numbers: 6546EH, 6546EG
Compatibility And Application
Fits Peugeot 207 models that use the above part numbers. The unit is intended for vehicles originally equipped with Bosch SRS control modules. Always check the part number listed on the original module to confirm match before installation.
How To Replace
Replacement of the airbag control unit should be carried out by a trained technician or an experienced DIYer familiar with SRS systems. Typical replacement steps:
- Park the vehicle on level ground, engage parking brake and switch off ignition.
- Disconnect the negative battery terminal and wait at least 10 minutes (or follow the manufacturer`s specified wait time) to allow SRS capacitors to discharge.
- Locate the airbag control unit (commonly mounted under the center console or beneath the passenger seat depending on vehicle specification) and remove surrounding trim panels as required.
- Unplug electrical connectors and unbolt the control unit. Take care with connector locking tabs and airbag wiring (usually yellow-coded).
- Fit the replacement unit, secure fasteners to original specification, reconnect all plugs and reassemble trim.
- After mechanical installation, clear SRS fault codes and perform any required initialization or coding using a compatible PSA diagnostic tool to ensure the unit is correctly recognized and airbags are operational.
Installation Recommendations
Safety first: Always disconnect the battery before starting work and observe anti-static and handling precautions for airbag electronics. Use appropriate diagnostic equipment (e.g., PSA-compatible tools) to read and clear fault codes after fitting. If crash data memory is present, the module may require specialized initialization or reprogramming to restore full functionality. Use genuine connectors and avoid damage to wiring harnesses during removal and installation.
Why This Part Fails Most Often
- Deployment in a Collision: The most common cause is airbag deployment during an accident, which records crash data and often renders the original unit inoperative until replaced or reprogrammed.
- Water Ingress and Corrosion: Moisture entering the unit or connectors causes corrosion and electrical faults.
- Electrical Surges or Short Circuits: Battery-related faults or improper jump-starting can damage the module`s electronics.
- Connector Damage or Wiring Faults: Broken pins, loose connections or abrasion can produce intermittent faults or loss of communication.
- Internal Memory Corruption: Rare EEPROM/flash corruption may cause persistent fault codes requiring reinitialization.
Notes For Professionals
This Bosch airbag control unit is aimed at workshops and competent DIYers. Proper diagnostics and post-installation verification are essential to ensure occupant safety systems operate correctly. Replace and reinitialize the module according to manufacturer procedures.
