Adblue OBD2 Emulator for Volvo Trucks 1. This is a Plug & Drive Ready device designed to emulate the operation of adBlue systems and NOx sensors on trucks equipped with EURO 4, 5, and 6 catalytic converter systems, including those with a non-functional adBlue SCR system. 2. It is easy to install. Simply plug it into the OBD2 connector of the truck and remove the specified fuses. 3. The device connects to the OBD2 port to simulate proper operation of the adBlue system and NOx sensors, even if the original SCR system is damaged. 4. This device is intended for use on trucks equipped with emissions control systems requiring adBlue functionality. 5. It enables the vehicle to operate without consuming adBlue fluid and deactivates NOx sensor functionality, maintaining normal engine performance without dashboard warnings or diagnostic trouble codes.
