How to Reset the BSI on the Peugeot

Model: Peugeot Peugeot Various
Part: Warning light – error code

The BSI unit centralises and processes information from three networks: - CAN HS network: "High-speed line" which includes all ECUs present in the engine compartment. - CAN LS comfort network: includes the ECUs present in the comfort CAN network and is a low-speed line; - CAN LS car network: connects the BSI to the ECUs of the assistance network, which is also a low-speed line. To reset this system, access the driver's seat, open and keep the driver's door open, turn the key and switch on the ignition but not the engine, and simultaneously pull both levers located to the right and left of the steering wheel and do not release them until you hear a sound. This way, you will have reset the BSI.
