Once VDASH has decoded the CEM pin it is stored on the VDASH servers and never revealed to you and Vdash will not reveal it to you.
2) Decode with ModUnlock
So ok, you are going to need the following :-
- Modunlock
- Maybe a car battery charger
ModUnlock DOES NOT need internet, DOES NOT need a DiCE, DOES NOT need a laptop, and only sometimes needs a car battery charger.
Modunlock MAXIMUM decode time for ecm is 4.5.
During the decoding the car is in very low power state , so a battery charger is optional. Also you can pause and resume the decode whenever you like.
Once Modunlock has decoded the CEM pin is is displayed on the OLED screen for you to use with which ever program you prefer.
3) Visit a Vdash Pro Dealer
If you are lucky enough to be able to visit a Vdash Pro dealer , they can offer a CEM decode services. Depending on the Dealer they may or may not be able to give you the CEM pin code to use yourself, or it may be hidden and stored directly with Vdash servers.

4) Contact a Vdash pro dealer who can do it remotely
If you have a DiCE and a Windows 10 / 11 64bit laptop, it is possible for a Vdash Pro to remotely decode the CEM pin.
It’s a bit of tricky thing to do, you need internet at the car, the car on charge and remote access to the laptop so the engineer can do the work required to get the CEM pin . This method puts the CEM pin directly in Vdash servers and it is never revealed directly to you.
