SCN Coding: Facilitating Software Calibration Number (SCN) coding after replacing modules.

1. Clean Install Xentry: Install your Mercedes Xentry software. Do not activate it yet. Do not connect to the internet.
2. Disable Antivirus: The enabler contains patches that antivirus software falsely flags as malware (due to memory patching).
3. Run the Enabler: Launch Xentry_Ignition_Top.exe as Administrator.
4. Select Mode: Choose "Top / Full Unlock." Do not choose "Lite" or "Demo."
5. Patch Hosts File: The enabler will ask to modify your hosts file to redirect Mercedes activation servers to 127.0.0.1 (localhost). Allow this.
6. Apply License: It will generate a fake license.dat file or patch the XentryRegistry.
7. Reboot: Restart your PC.
8. Test: Launch Xentry, select "Offline Operation," and attempt to code a simple module (e.g., resetting an airbag light via SCN). It should succeed without an internet cable plugged in.

Actuations: Tests specific parts like fuel pumps or fans in real time .

Many XENTRY functions, such as clearing fault codes or starting specific adaptations, require the software to "see" the ignition being cycled OFF and then ON. If the hardware does not report this change, the process will stall. This tool allows the user to manually click a button to "tell" XENTRY that the ignition has been turned. Usage Context Target Users: Independent mechanics or DIY enthusiasts using XENTRY Pass Thru instead of the expensive, official Mercedes-Benz XENTRY Diagnosis VCI Common Platforms: It is frequently found on automotive forums such as Digital Kaos as a community-developed fix for non-OEM hardware. Alternatives For users with official Mercedes-Benz hardware, such as the XENTRY Diagnosis Kit 4

• Connect the Xentry device to the vehicle's diagnostic port.
