Aftertreatment instructions
ATTENTION! Besides our programming, there are a few steps that should be completed. EGR: Block the EGR flow. Disconnect theEGR valve, differential pressure sensor, and temperature sensor. Warning #1: do not confuse the EGR valve and camshaft position sensor connectors. These connectors are close by and very similar. DPF/DEF: Disconnect the following components: ACM MODULE, Sensor NOx Inlet, Sensor NOx Outlet. Warning #2: do not disconnect the entire DPF harness, it may contain important engine-to-transmission or transmission-to-gear selector datalinks. Insulate all disconnected connectors to prevent corrosion and short circuits. The DPF should be removed physically. We also strongly recommend bypassing the SCR cans or removing them.Equipment requirements
