I have a Volvo XC90 2018 model with CEM SPC5656C - ON32E which is damaged and not identified on car or bench.
I had previously read the CEM immo data before and is available.
Is it possible to adapt a used replacement CEM?

- Use jumper wires to connect the programmer to the module’s board.
- Reference the wiring diagram for the 0N32E MCU pinout (often found in XP400/XP401 documentation or Autohex/Xhorse/CGDI diagrams).
Backup the Original Module:
- Read and save D-Flash and C-Flash from the original (old) module.
- Verify the read was successful (check file sizes and checksum if possible).
Backup the New (Replacement) Module:
- Before writing, also backup the D-Flash and C-Flash from the new module in case recovery is needed.
Write to New Module:
- Write the D-Flash and C-Flash files you read from the old module into the new one.
- This process can take some time — ensure the XP programmer is fully powered.
Install the New Module:
- Reinstall the cloned module into the car.
- The vehicle should recognize the original key(s).
- Existing car issues may remain, but the module will be properly initialized.
