Proper relearn procedure after battery DC

[BOB F]

i searched best I could but could not find this.

Is the correct relearn procedure published on posted somewhere?

Could somebody please post it maybe from the repair manual ?

What do you mean relearn? If you're talking about the ECU recalibrating the fuel mapping, etc., it does that on it's own over time and driving.

There are some vehicles which have specific guidelines and procedures to do this. I have factory documented publications on this for one of my cars.

I did find some generic suggestions for how to best accomplish it but was asking if there was a specific protocol outlined in a service manual.

These aren't computer heavy vehicles, the battery does not have to be registered with the ecu. Just plug it in and go. You'll have to re-enter radio presets and things like that but nothing special is needed.

I agree with trunkmonkey tho, after putting in a new battery the ecu will make some adjustments over time.

I just had to put a new battery in the wife's car and a dealer trip was mandatory as the new battery had to be registered directly with the ecu. I tried in vein to get around this but everything I came across said dealer program was mandatory. $350 for the whole thing, probably the most expensive battery I've ever bought!

If you mess with the fuel or air system - cleaning TB/MAF, replace an o2 sensor, etc., you might see some "relearning", but just replacing the battery or disconnecting it - I doubt you'll notice anything.
