CKP after battery charge.

Opinions will vary, as will results. I have not found much difference and where there was some shifting sooner or later than before...etc. etc. It seemed to sort itself out in a few miles.

I believe it is largely an adaptive system that in time (and the longer the battery is disconnected the longer the time) will drive the same again. CKP and ILP may speed the process, but in the case of the 'normal' battery change-out, I doubt it is worth the effort, but 'it can't hurt'.

I agree with rollinhonda.

I've never experienced any benefit doing the ILP or CKP procedures after a battery swap. Furthermore, next battery swap I'll use my jump start battery to power the system via the OBD2 port and won't lose any power to the system.

Yes, one of those things I've remembered after the fact.

I was just wondering what anyone thoughts of after clearing codes through the OBD2 (like after a check engine light reset).Wouldn't that be very similar to disconnecting the battery.I know some people do this to try and shut off a check engine light if they don't have a OBD2 reader.So in theory a ILP and CKP should be done as well.?

Again, the system is self-learning. I think if codes are caused by a problem with the truck, they will eventually appear again. Just as the truck will run the way you drive it, eventually.

I just replaced my battery about a month ago. Did the swap, started it and drove it home. No ILP, CKP. Everything seems the same as it was the fuel mileage didn't change any. The only thing I had to do was enter the radio code and set the clock. I didn't even loose my presets.
