Is it possible to replace a sim module with 908 with a sim module with 93LC76 inside.

For programing need pin code from old cim or from new cim?

i think you need find same cim as ori
2nd answer - yes - you need pin from ori and donor then reset ori and coding donor to car.

I found three, but all three are different. There was no way to program a different module?

If both cim have esp or not ,and the same type (93c76 or hc08) you can swap eeprom/mcu and the car will start just fine .

Did you have a way to find out if the module is with 908 without disassembling it?
Serial number or something else?

[rafal]

you wrote gm part number - you should have two letters after number

Are you sure it will work, said to look for the same with 908 inside?
After the test, if it doesn't work, will I be able to return the old cim and program it ?
I'm a little worried, for the first time I will swap cim module!

You can always come back to ori.
