What (e.g., C4, C5, or C6 VCI) are you using to connect to the vehicle?
Generate keys for long-term activation and specific diagnostic modules.
Modern Xentry variants use auxiliary packages like DAS (Diagnosis Assistance System) and Smart Calc.V2.1 generates concurrent strings for these legacy subsystems.This guarantees seamless workflow transitions when diagnosing older models (pre-2015). System Requirements and Prerequisites
