Step 1. To begin your fault code reading process, you’ll need to enter the correct electronic control unit for the model you’re working on.The SCR's job in the Emissions After-Treatment System (EATS) is to lower the NOx level emitted into the atmosphere. The performance of the SCR is evaluated by the NOx sensors. There are NOx sensors that are located on upstream (inlet) and downstream (outlet) ends of the SCR. Important: the SCR is the last component in the EATS which makes Try disconnecting your batteries for 10 minutes and rerunning the scr test to check the NOx sensors. There is a dpf analyzer is insite that will test exhaust flow, intake and your turbocharger and give you a pass/fail on the quality of a regen. Check your decomp tube for def buildup and check over the tsb for scr efficiency.
