Description
BSI Control Unit 2004 H01-00 JOHNSON CONTROLS for CITROËN and PEUGEOT vehicles. It is from a Peugeot 307 2006.
This BSI (Body System Interface) control unit 2004 H01-00 is a central comfort and body electronics module used in Citroën and Peugeot vehicles. Supplied with reference numbers commonly searched by workshops and DIY mechanics, this unit is ideal when replacing a faulty BSI in compatible vehicles. Clear product codes and OE numbers make it easy to find the correct replacement: 9664968980, 1660728880, 6580QH.
The module manages multiple vehicle functions such as central locking, interior and exterior lighting, wipers, power windows, alarm and remote functions, and communicates with the immobiliser and engine control systems. Replacing a failed BSI restores control of comfort features and vehicle body functions that can otherwise render a car inconvenient or immobilised.

Compatibility
Originally sourced from a Peugeot 307 (2006). Fits selected Citroën and Peugeot models equipped with the BSI 2004 H01-00 / matching product codes. Always verify the part numbers printed on your original unit against the product codes above to ensure fitment.
Replacement And Installation
Typical location: Under the dashboard on the driver side, often near the steering column or glovebox depending on model year. Basic replacement steps for experienced mechanics:
- Disconnect the negative battery terminal and wait a few minutes to discharge residual power.
- Remove the relevant interior trim panels to access the BSI unit.
- Unscrew mounting fasteners and carefully unplug multi-pin connectors (note alignment and locking tabs).
- Install the replacement unit, reconnect connectors and secure mounting screws, then reconnect the battery.
- Follow coding/initialisation procedure (see Installation and Coding – Important below) to restore vehicle functions and immobiliser communication.
Installation and Coding – Important
- The unit is used and is paired with the original vehicle (VIN/PIN/keys).
- Options to make the unit operational:
- Clone data from the old unit (EEPROM/Flash) – after cloning the unit becomes plug and play.
- Virginise and then initialise/telecode via DiagBox (or online) + adapt keys.
- Recommended to be performed by a technician with PSA service equipment (DiagBox/Lexia/PP2000).
- Always disconnect the battery before removal/installation and follow the manufacturer’s procedure to avoid damaging the unit.
Why BSI Units Commonly Fail
- Water ingress or moisture from leaks (e.g., windscreen or door seals) causing corrosion.
- Voltage spikes, poor battery connections or incorrect jump-starting damaging internal electronics.
- Oxidised or loose connector pins leading to intermittent faults.
- Thermal stress and ageing of solder joints or electronic components over many years.
Recommended For Installation
- Have the unit installed and coded by a qualified technician with PSA diagnostic tools for reliable result.
- If cloning is selected, ensure the original EEPROM/Flash data is successfully copied to avoid immobiliser or functionality loss.
- Protect connectors from moisture and ensure seals are intact after reassembly.
- After installation, test all comfort and safety functions (locks, lights, wipers, immobiliser) before returning the vehicle to service.
This listing targets professional mechanics and competent DIY enthusiasts familiar with vehicle electronics and PSA coding procedures. Clear OE numbers and model identification help locate the exact replacement part quickly.
