Where would the ACM be located? 2014 Peterbilt 337 with Cummins ISL.
Got flashing def light and 5mph derate. Changed both filters in the def tank. Replaced the doser unit. Replaced both nox sensors. Truck still in derate with light flashing. Any advice? Thinking may have some wiring issues? Thank you.

Did you have the ECM reset after the work was done?
-
Yes. Now I’m getting a 3712 fault code.
-
If you have tried resetting all active/inactive fault codes with Insite after successfully making the correct repairs and the 3712 code is still active, you are going to have to update to the latest calibration available.
-
Thank you. Yes cleared all codes, the 3712 is staying. I’ll try the latest calibration.

3712 should not be active all by itself and is an scr derate only. I agree to reflash if it truly is the only fault that remains. I have seen this before with 3714 but never 3712. A list of the original faults would be helpful to get us to a root cause.
ACM location can vary by chassis but is typically located in close proximity to the DEF tank or somewhere inside the frame rails near the trans. A VIN could get us closer. -
Original code was 3216. I replaced the intake Nox sensor. That code is no longer active.
VIN 2NP2HJ7X7EM240255
Thank you
