Volvo XC90 2016+ adapting a used CEM, possible?

[carkeymasters]

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?

Yes, it can be done.

• 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.
