Replacement Procedure (General Guidance)
Replacement of the BSI should be performed by a competent mechanic or an experienced DIYer who understands vehicle electronics. General steps:
- Disconnect The Battery: Always disconnect the negative battery terminal before removing the BSI to prevent damage.
- Locate The Unit: The BSI is typically found behind the dashboard or under the glovebox on Peugeot 206 models; remove the trim panels to access it.
- Label And Unplug Connectors: Mark connector positions if necessary, then carefully disconnect wiring harness connectors and remove any securing screws or clips.
- Replace The Unit: Fit the new or replacement BSI, reconnect harnesses firmly and refit trim panels.
- Coding Or Initialization: After installation the unit will usually require cloning or coding to the vehicle (see Installation And Coding – Important section).
- Test All Functions: Reconnect battery, then verify central locking, lights, wipers, and other controlled functions before returning the vehicle to service.
Installation And Coding – Important
- The Unit Is Used And Is “Paired” With The Original Vehicle (VIN/PIN/Keys).
- Activation Options:
- Cloning Data From The Old Unit (EEPROM/Flash) – After Cloning The Unit Is Plug And Play.
- Virginization And Subsequent Initialization/Telecoding Via DiagBox (Or Online) + Key Adaptation.
- Recommended To Be Performed By A Specialist With PSA Service Equipment (DiagBox/Lexia/PP2000).
- Always Disconnect The Battery Before Removing/Installing And Follow The Manufacturer Procedure To Avoid Damaging The Unit.
Recommendations For Installation
- Perform Coding Or Cloning With The Correct Diagnostic Tools — Improper initialization can leave vehicle systems inoperative.
- Inspect Connectors And Wiring For Corrosion Or Damage Before Reinstallation; Repair Any Faulty Grounds.
- Secure The Unit Against Moisture And Ensure Cabin Seals Are Intact To Prevent Future Failures.
- If In Doubt, Use A Professional Workshop Equipped For PSA Electronics.
