I’ve just got Vediamo V4 up and running for a Smart 450 Cabrio with a dead SAM unit, to virginize (Or at least reset) a 2nd hand SAM unit and program it in.
However, vediamo no make virgin this unit for smart
And i was told to make virgin by eeprom dump and make initial startup with Xentry/DAS, and also put the Sam and start the car ..but to change the vin only EPROM and km …
I have access to a eeprom reader so can do that with a SAM but I’m struggling to find a virgin SAM backup. (have found the one for the MEG at the back but not one for the SAM)
But i found it would not help because by coding with Benz diagnostic tool i have to enter the SCN Coding Chucksum. Only official smart service can get this number. A smart owner said it worked only by coding the meg and dssh to the 2nd used sam unit. So yes, only a open DAS and the right vin.
Password may be required in official dealer for matching a new key to a control sam used
So i use the non password fix for DAS to get it, I’m sure the SAM unit will take any 3 button key you throw at it (unless it was a 1 button early MCC)
Ps. The fix from Obd2tool.com.
Not for coding a new set of blank keys into SAM, just go into
SAM Unit –> Adaptations –> Bottom of the list should be Special Function: Reprogram keys if no keys available
It does require a password unless you have the No Password fix, I did this the other day on DAS 04.2014 with 2 new keys (No originals)
The fix bypasses the password requirement (Just press F2 twice)
