E-Sys
Good question. Should have started out with that...I guess.
E-Sys is the program that is used to reprogram the modules in the F-series vehicles. In other words, if you want to program your mirrors to fold when you hold your remote button, or close the trunk with the key fob you do it using e-sys and a specialized cable (ethernet to OBDII).
This is the first sighting of the program and activation tools to get communication with the car.
