Infineon 21002558 (SAF Xc161cj 16F20F BB) on GM instrument cluster

[anton74]

Hello,

I am trying to read the data from the MCU of the GM (2005 Chevy Trailblazer) instrument cluster board.  The MCU is Infineon 21002558 which is actually the SAF Xc161cj 16F20F BB (I found this information in this video - ).  So, I am using MiniMon software and it seems like I can connect and read the MCU.  I want to copy the entire firmware of the MCU in order to program another, blank MCU.  What sectors should I select and how I can be sure that I copied all the necessary information?

Thanks!
