Proper Procedure for PCM reset, please.

[NotAFordGuy]

What is the proper procedure for resetting the PCM in our 03 Ford Explorer 4.0L V6, all wheel drive Eddie Bauer model? I thought you just had to pull the negative battery cable for a while? How long? Or am I not even close to being correct? Any help is greatly needed and appreciated.

He pulls the negative side as you say but also runs a jumper wire to the hot for a bit.

@NotAFordGuy Meaning, with the Negative cable disconnected, touch it to the Positive terminal, or join the two with a jumper wire. This discharges capacitors in the modules. Obviously, DO NOT do this with the battery negative post still connected! imp
