Mercedes ML270 W163 2oo4, Lower Console - Power window switch problem

[WinWoj]

Hi Friends.
As I subjected, W163 lower console module problem. I measured all ground, terminals 30 and terminal 15. I scoped CAN - everything OK. Also diagnostic K-Line is continues, so I decided to replace module, because not detected in star diagnosis.. But I carry I bought bad one, because also not detected... Earlier I replaced AAM module, but I think is no matter, because not coding option for this lower console in stardiag...

Maybe someone had succes with repair it. Module has two HC908AZ60. Because I haven't comunication via K-Line I think MCU's dead.. Sometimes read/write procedure helps, so I will do this using ETL.

Central Locking - OK
Windows - Not OK
Mirrors - Not OK.

Have you followed the can lines from the pin through the PCB till the MCU?
I am asking, in case a component before the MCU is faulty, or even dry joints on the solder...

No, good topic... I only test path from pin to CAN tranceiver and replaced it, because I had one from another module... But not tested path from tranceiver to MCU... thanks
