MrS,
Completely Valid on the circuit. You are correct. Closed circuit, or completing the circuit is a more accurate terminology.
A battery change can cause unexpected side effects in modern Computer Controlled vehicles, none that are a real problem. Also if the battery is changed relatively quickly the capacitors aren’t drained and the KAM is not cleared, and very little has to be relearned, if any.
I have been programming on cars since I got rid of my 76 Nova and went to my first electronically controlled fuel injected car. That happened to be a Geo Storm, Yes a geo. It had a Lotus designed, Isuzu manufactured 4 cylinder, and could really light the tires with the right tweaks. Nova was terrible on gas, and needed something dependable to run back and forth to college.
When programming I learned the trick I told J07 to do. Sometimes it was needed to get things to behave like they are supposed to. I have never used the Jumper trick, and don’t plan to in the future. I have used the method I laid out on My Old 250, and many VW’s when I used to change tunes to get them to relearn shift stragedies, and forget what it previously knew. It works, as proven today.
No need to do this unless you are experiencing a problem. I have used it to help a friend with a Dodge 2500 that was having rough shifting. Disconnected the battery, left HeadLights on, let it sit, we had a Beer. Came back after a bit, connected everything back up, started up and went for a nice slow drive around the area. Now his random hard shifting has gone away. He uses a programmer, and had done a bunch of changing of the tunes recently. I think that got the Trans out of whack.
Have a great rest of ya’lls evening!
