I had planned on removing my TCU when free MFM expires to eliminate some of the drain on the 12V battery when the car is off. Out of curiosity I pulled the fuse for the TCU to see if anything else would stop working. Since I couldn't talk to the car any more via MFM I got the right fuse. It's in the fuse block on the driver's side in the rear hatch area. The 5A fuse in the bottom right hand corner in case anyone is wondering. Anyway. I've noticed that "GO times" and "Value charge" no longer function. You can't even change any setings like if you wanted to setup GO times. It simply won't let you enter anything. If you had value charge settings enabled before pulling the fuse those settings will appear to be there but you cannot change anything and the car will default to "charge now" even though it says it will value charge at whatever time you had set it to. I pulled the 12V battery thinking it was a glitch and I just needed to "reboot" things. Well after rebooting the screen showed neither "value charge" or "charge now" as selected and still could not change any settings. Plugged in and sure enough it immediately started charging. So am I missing something or does the car need the TCU for some strange reason for "GO times" and "Value Charge" to function? Seems really odd unless Ford did something stupid and it relies on ford's MFM servers to function. That would be a really dumb way to handle "GO times" and "Value Charging."
