Some 2016 Ford Econoline vehicles equipped with a 6.8L engine and built on or before May 27, 2015, may exhibit an illuminated MIL, with DTC P2610 stored in PCM memory after the 12-volt battery has been disconnected.
Reprogram the PCM to the latest calibration using IDS release 95.05 or higher. Make sure you are connected to the internet when entering module programming to obtain the latest updates.
