If you want to reset your Power-train Control Module(PCM), Ford calls it Electronic Control Unit(ECU), a.K.A. The "computer" on your vehicle, simply take the negative battery cable of the battery for at least five (5) minutes. This will completely erase the vehicles Keep Alive Memory (KAM). However, you should record any Direct Trouble Codes (DTC)'s a.K.A. "codes" before you do. All information will be lost. It is the equivalent of doing a factory reset on your cell phone. I have included an informative diagram below.
