AdBlue Emulator V4 EVO installation manual for Volvo FH4/FM4 EURO 5 trucks

AdBlue Emulator V4 EVO FH4 EURO 5 is compatible only with Volvo FH4/FM4 EURO 5 trucks. This installation manual describes the whole process of AdBlue Emulator device installation on compatible Volvo FH4/FM4 EURO 5 vehicles. We highly recommend you to delete all DTC (Diagnostic Trouble Codes) errors from OBD (On-Board Diagnostics) system on your truck. The best option is to use the original Volvo diagnostic scanner. Also, it is recommended to check the OBD system after installation of AdBlue Emulator module because there might be errors related to installation procedures.

Vehicle preparation! To make sure that the emulator works as intended, you would need to launch active DPF regeneration before installing the emulator. To do that, you need to connect the vehicle to a diagnostics system (original Volvo or TEXA) and activate the regeneration function.

Connection diagram. Attention! Pay attention to the emulator sticker; colors of wires may vary.
