Hello everyone! Looking controllers memory MC9S12DT256 mask 1K79X and MC9S12DG128 mask 0L85D. Share, please. Thnx!

[ricked]

post part number, also "all" software is linked/sync from mcu 1 to mcu 2

numbers on CEM-box Volvo 30728906 130206 03731311 519096408 060347. I read mcu, but doubt dumps is correct? I have problem in CEM, no functions in car, even hazard light not. This happened after trying to read a china xprog-box555 and resoldering the board (change transistor from inside). I will check issue in soft or in hardware.

yes i know, i did confuse with other algo

as for cem programming, even ori xprog/vvdi have sometime problems with this cem resulting in no start and clicking of relais, solution is reprogram it again and read cem on bench with diagnosis tool, if you can read it with that your done
