There are some videos on the internet showing you how to read BSI on Peugeot Citroen using Uber or Xprog or other clones, but not a video using CG Pro 9S12 Programmer. So this post will show you the easy steps to read BSI with CG Pro.

Connection:

I make the connection according to the diagram of X-stroke.

P7: RESET, P5: GND, P9: VDD 5V, P6: BKGD

There are almost the same connection you can also take your points you can take the multimeter and you can check for continuity and you also can search on the board you’ll still have different choices where you can solder these cables.

Operation:

I try many times to read BSI with CG Pro software until I have the result because at the first time I have only issues with this one.

Of course I selected my MCU and after that I selected Motorola- HC(9)12 and HC912DG128-0K50E.

I’m trying to read all of this. What I want to mention you should read the EEPROM. You need the EEPROM and you don’t need the Flash. So I select EEPROM and click Read to start the process. The chip is encrypted. It’s trying to make decrypting of this chip, but with no result. I tried to select other models, also failed.

So finally I select HC912DT128P-2L05H. This one actually works!

It’s very fast to encrypt the chip. Then save the EEPROM data read out.

After that, I will proceed to write back. Click open to select the related BSI EEPROM file to open.

My mind is not modified it was just deleting the errors. Then click Write to write the data back. Wait a moment to match chip, verify encryption and write data. It seems to take much longer.

I totally honest I didn’t know if these things worked or not. It’s the first time done.

Great! It’s successful.
