re-calibrated my 2017 FL m2 106 6.7 isb and now Electric faults are showing?

Vehicle = 2017 Freightliner M2

According to the VIN# and the engine ser#, it is supposed to have program DT90275 in it, so the program is not the issue unless its corrupt, or some idiot did not make a backup of the ecm template before updating it.

Even with the ecm template missing, if it is the correct program for the ecm (and in this case it seems to be), this does not account for engine sensor faults. Faults that are typically seen when the vehicle template is missing are cruise control, engine brake, maybe fuel pedal, but not any engine sensors.

Updating the software will not cause sensor issues like you are describing either ... so either you have bad sensor(s), or some wiring problems somewhere .. or a fried/damaged ecm.

What are the exact faults showing in Insite, and not some trash third-party device codes?.

BTW: All the sensors run on 5 volts. Register the engine ser# on quickserv.com and get access to the ecm wiring diagram .. ensure things are hooked up properly, have the right voltages, etc. and that some moron has not crossed some wires somewhere.
