Can you discinnect the battery on an iveco daily the way you can on a transit to clear some electronic faults?

Disconnecting the battery, and leaving it disconnected for five to ten minutes will reset the Engine Control Module. This will clear electronic fault codes, but most likely won't do anything to actually fix the fault. If the fault is still present after resetting the ECM, then repairing it will be a more involved task. How to go about doing that will be impossible to say without knowing the nature of the fault(s).
