Compatibility And Application

Intended For: Peugeot 407 (example vehicle: 2007). The module is compatible with Citroën/Peugeot models fitted with the BSI 2004 H05-01 hardware and corresponding product codes. Always confirm physical part numbers on the original unit before installation.

How The Unit Is Replaced

Replacement Steps (overview for experienced technicians):

• Disconnect the negative battery terminal and wait several minutes to ensure capacitors discharge.
• Remove lower dashboard trim panels to access the BSI (location varies by model; commonly on the passenger or driver side behind glovebox or under steering column).
• Unscrew mounting fasteners and carefully release the electrical connectors using proper terminal release tools to avoid damaging locking tabs.
• Swap the unit, secure mounting, reconnect all connectors and reassemble trim panels.
• Perform required coding/initialization (see Installation And Coding – Important section below).

Installation And Coding – Important

– The unit is used and is “paired” with the original vehicle (VIN/PIN/keys).
– Options for commissioning:
1) Cloning data from the old unit (EEPROM/Flash) – after cloning the unit is plug and play.
2) 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).
– Before removal/installation always disconnect the battery and follow the manufacturer’s procedure to avoid damaging the unit.
