⚠ WarningTo carry out this adaptation the EZS must be taken to virgin state as well: if you personalize the EZS with the Abrites default data all previous keys are lost and new keys have to be programmed. Virginizing requires an internet connection.
Procedure
Start by reading the ESL/ELV in the "DAS Manager".
Virginize the ESL/ELV: this part requires an internet connection.
Wait for the ESL/ELV virginizing complete message.
