Description
BSM Delphi R02-00 for Citroën and Peugeot vehicles. May have a cracked mounting tab on the housing, which does not affect function. Unit is fully functional.
Product Overview
This BSM (Body System Module) R02-00 is a direct-fit electrical control unit used on a range of Citroën and Peugeot models. It manages multiple body functions such as lighting circuits, central locking, wipers, power windows and related relays/fuses. The unit supplied is fully functional and may show minor cosmetic damage to a mounting tab on the housing that does not affect operation.
Key Benefits
- Direct replacement for original BSM R02-00 modules with matching product codes.
- Restores central body electrical functions quickly — ideal for workshops and DIY mechanics.
- Cost-effective alternative to dealer-priced parts when the unit electronics are intact.

How It Works
The BSM consolidates several body electrical controls into a single module. It interprets inputs from switches and sensors and drives relays and outputs for lights, wipers, windows, and central locking. Faults in the BSM can result in multiple, seemingly unrelated electrical symptoms, such as non-functioning indicators, intermittent wipers, dead central locking or blown fuses.
Typical Failure Modes
Common causes of BSM malfunction include:
- Moisture ingress or condensation leading to corrosion on connectors or circuit board tracks.
- Electrical surges or short circuits that damage internal components or solder joints.
- Connector corrosion and poor contact at multi-pin plugs.
- Mechanical damage to relays or terminals inside the module.
Replacement Procedure (General Guidance)
Recommended general steps for replacement (always follow the vehicle manufacturer service manual for exact procedure):
- Park vehicle on a level surface, engage handbrake and remove ignition key.
- Disconnect the negative battery terminal before starting to avoid short circuits and protect vehicle electronics.
- Access the BSM location (commonly behind glovebox, under dash or in engine bay depending on model) and remove any trim or fasteners.
- Carefully unplug all electrical connectors, noting connector orientation and locking tabs.
- Remove the module from its mounting. If a mounting tab is cracked, ensure secure re-mounting using the correct fasteners or a suitable bracket.
- Fit the replacement unit, reconnect all plugs and secure the module. Reconnect the battery and verify all body functions operate correctly.
Installation Recommendations
- Always disconnect the battery before removing or fitting the BSM to prevent damage to the unit or vehicle electronics.
- Inspect connector pins and wiring for corrosion or damage and repair as necessary before installing the new unit.
- Ensure the module is mounted securely; a cracked housing tab is cosmetic but the unit must be fixed to prevent vibration-related issues.
- After installation, test all related functions (lights, wipers, windows, locking) to confirm correct operation.
- If multiple electrical faults persist after replacement, check fuses, ground points and related wiring harnesses for underlying causes.
Why This Part Most Commonly Fails
Failures are most often caused by environmental exposure (moisture and dirt) and electrical events (shorts, surges). Corroded connectors and intermittent contacts are frequent culprits. Addressing wiring and connector issues at the time of replacement reduces the chance of repeat failure.
Notes
Check the physical part numbers and connector layout against the vehicle unit before installation to confirm fitment. This unit is supplied as described and is ready for installation when connectors and vehicle wiring are in good condition.
