BSI Repair

[mexanico1971]

I will tell my experience with this Xsara 2 car.
They have been shown to be a common failure for direction indicators to fail while the instrument panel shows proper operation. It is imperative that the rear windscreen wiper and the heater do not work with this failure. I have read many posts in the forums and no one has written how they solved this problem. After much pain, I was able to find the fault. Looking at the scheme from Autodata into the work for outside lights, everything was right. Which was a problem in finding the error. There is nowhere a BSI pin scheme where all power and outputs can be seen in one place. THE WIPER WIPER SCHEME MUST BE WATCHED. There you will find two fuses F17 and F27 one of the voltages is certainly missing. Many masters tried to replace the BSI to solve the problem but the problem was not solved.
I will also describe the easiest way to replace a BSI with another from another car.
After many hours of torture with Peugot, Citroen and Renault cars electronics, the simplest replacement procedure for BSI is as follows:
Eeprom content is copied from the original BSI and a new (replacement) BSI is copied to Eeprom. Physical replacement of Eeprom can also be made. Now the car just won't want to start because the old keys have to be logged in with a Lexia tool. If the keys cannot be used, use a new empty transponder.
Why is this the simplest? Save Lexia programming hours with the tool. You certainly do not know the exact configuration of the car: which is the gearbox (there are about seven), whether it has a rear wiper or not, what type of cassette player, what is the car PIN, what is the car chassis number .....

Conects to another A point of other part of wiring diagram. Your wiring diagram is not complete....must have other part/parts from this diagram.
