Hi my name is***** will be glad to try to help... that is only the last part of the codes, FMI 1 and FMI 31... There should be an SPN number before those numbers. Let me know the full code numbers and I will look them up for you.

SPN 2003

Thanks for the update. That code is voltage above normal - Communication link lost between TCM and ECM.

Check the harness and connector pins for damage and verify power and ground to the ECM and TCM. Check the inline fuses between the battery box and ECM as well as for corrosion and wire damage. If all checks OK try a test TCM and ECM or have yours bench tested.What make chassis is this street sweeper? Are there any cruise control set resume switches to pull engine codes or do you have a scan tool?
