I apologize for the delay. The 5394 fmi 5 is for open circuit to the def doser. The 3936 is for soot load. The 5246 is essentially a derate fault that is aftertreatment related. The 173 is for the ex gas temp sensor open circuit. The other 2 faults you have are for open circuit to the t2 and t3 temp sensors in the dpf. I hope this helps. Thank you
