What is the BSI in Peugeot cars?

Dongfeng Peugeot BSI refers to a fault in the interior body control unit, which can be checked with a computer diagnostic tool. Generally, resetting the Peugeot BSI is also known as initialization. To perform this operation, a Peugeot-specific diagnostic tool is required. The specific steps are as follows: Select the vehicle model and enter vehicle identification; input the DAM number (taking the Peugeot 307 as an example, the DAM number is located on the inner side of the right front fender), perform a test on the control unit; select the central switch unit BSI, connect the OBD diagnostic head, turn on the ignition switch, and select initialization settings. Resetting the Peugeot BSI requires connecting a fault diagnostic tool. If your Peugeot BSI needs to be reset, it is recommended to take the car to a 4S shop for professional handling and not to attempt it yourself.
I think the BSI in Peugeot cars is like the brain of the vehicle, responsible for managing all the electronic functions of the car body. In my Peugeot, it controls the door lock switches, window lifts, and even the anti-theft system. If you press the unlock button on the car key, the BSI module quickly responds, making the lights flash once to indicate OK. It also communicates with other systems via the CAN bus, such as when the air conditioning starts, the windows automatically close a bit to save energy. If the BSI malfunctions, common issues include doors not opening or windows getting stuck. The troubleshooting method is to connect an OBD device to the diagnostic port to read the fault codes. For repairs, it's recommended to go to a 4S shop to replace the module or update the software. I think regular maintenance can extend its lifespan, after all, it safeguards the vehicle's safety and prevents accidents.
