AdBlue Emulator EURO 6 NOx installation manual for Volvo trucks (with retarder system)

AdBlue Emulator EURO 6 NOx is a device made to override SCR system on Volvo EURO 6 trucks. The manual that you’re now reading is for emulator installation only on Volvo EURO 6 trucks equipped with retarder system. You can use this emulator on Volvo EURO 6 trucks without the retarder system if you need the support for 2018 firmware versions of truck ECU. Incompatible with EURO 5 and trucks with lower EURO standards. Incompatible with vehicles made by other manufacturers.

We highly recommend you to delete all DTC (Diagnostic Trouble Codes) errors from OBD (On-Board Diagnostics) system before you proceed with the installation process. The best option is to use original Volvo 88890300 or any other compatible diagnostic scanner. If you noticed new DTC errors after installation, please recheck the system with the diagnostic scanner because there might be errors related to incorrect installation. For the safety reasons we highly recommend to start the installation by connecting a ground wire, it’s safer for the emulator and your truck.
