I read a couple of post that mentioned the ridge actually learns your driving habits ie cruise control, gas consumption etc.

When I purchase mine should I reset everything by dislocating the battery or just let it roll?

I don't know the origin of your parania, but it seems you have discovered the magic Remedy!

From what I've heard, it does "learn" your driving habits, as long as you have your radio code, I don't see any reason why you shouldn't dis-connect the battery for a bit.

All I've found is the "idle learn procedure," which is how the engine learns about itself and its environment—atmosphere, grade and quality of fuel, and how the engine itself operates—in order to set an optimum idle speed. It's possible to reset it, but ideally this is just one of three computers that should be reset.

If you are purchasing a used Ridgeline, and you're moving it to a different location than the one it "lived" in, you might consider resetting it.

if you have ever hooked your ridge up to an obd2 scan tool with live data you would see that temp,humidity, 2 o2 sensors,throtle position,bank 1&2,are just a few items the computer is reading.

it's a known fact that sometimes you can help your vehicle (any vehicle) with simple re-boot if it gets confused.
A good scan tool is just that though.

I understand that. That's the emissions control information that pretty much every modern vehicle requires in order to adjust its operations for minimum emissions moment-to-moment.

But what I think the OP is saying is that the Ridgeline is making persistent ("learned") adjustments to its settings based on things like driving habits.

My '92 Plymouth Voyager (yes, I drove a minivan once!) had a automatic transmission that did just that: learned the driver's operating habits and adjusted its shift-points for smoother operation. Dealers had to counsel new owners to be patient until the tranny "knew" them. And, the settings would be lost whenever the battery was disconnected, meaning the transmission shift-points would have to be learned again.

Early versions of this transmission, especially in the Grand Voyager, were unreliable enough that Consumer Reports called the vehicle "Not Acceptable", as I recall.


So to mjb-ridge: is that what you had in mind? And would you mind linking those posts if indeed it is?

And to everyone else: is there any part of the Ridgeline's operation that works that way, and would mjb-ridge benefit from a reset?

Goddammit, Im still waiting for it to learn my gas mileage!:act060:

Going through the service manual, the only thing I found about learning (other than the idle learn procedure and a CKP learn, was for the brake assist. Here is what it says:

the onboard computer runs quite a few more engine items other than emissions, learning is a loose term.
PCM's will learn the components and adjust for fuel, air, temp.
Be glad we don't have the pcm's of the early 90's they were quite stupid.

Ridgeline PCM info located in service manual PCM reset and clear 11-4 Readiness Codes 11-64 Idle learn 11-256


the computer (s) will compensate and adjust if that is what is considered by some to be learning, but then again so do the distributor springs in my 64 goat, as I push on the gas feed.

perhaps many are confused on this subject and actually are referring to replacing a pcm in a vehicle or updating one

what ever vehicle with obd2 when a new computer is installed you will have to make it "re-learn" the vehicle (remember you have alot of sensors "different voltages than the last engine etc" and other computers) you just put it in. just that simple

example when i have put a new engine in a vehicle before i start the car i turn the key to on without starting the car let it sit for a while while the computer cycles. goes without saying accessories are off.
What has always worked for me was to to this a few times.
Next turn on the key again wait for a few seconds then start it this time run till it comes to temp then shut off
re start as above and run 2-3k rpm for a few minutes, then let sit for a bit a idle and check for codes and done.

The pcm is always adjusting and tweaking, if your idle speed is high or low you can reboot or "relearn" also but I would wonder why that happened, new battery?, defective part?

something that I was saying before was it is good to get a obd2 scanner then bench mark with live data when you engine is running great. Very handy when it is not to make comparisons.

See up-thread. I agree with you that "idle learn" is a form of learning, but I don't think that's what the OP means by it…unless he himself checks back here and says so.

Also see up-thread about the "brake learning" modality, which is somewhere between what you are describing in resetting "idle learn" and what I was describing with an AT from another vehicle. That would be something that is learned over a driving session (defined as the period from "ignition on" to "ignition off"), then erased until the next session.

Going through the service manual, the only thing I found about learning (other than the idle learn procedure and a CKP learn, was for the brake assist. Here is what it says:

That's something I did not know, and very cool. Thanks!

It appears to clear whatever it "learned" about the driver's braking behavior when the ignition is turned off. That would make sense, because it could very well be another driver operating the Ridgeline next time.

My wife and I routinely share driving duties during long trips, and we sometimes switch seats without switching off the engine. Maybe we'll change that habit now. :)

If you buy one new, you should redo the idle learn procedure. (dealers can't be trusted) If you get one USED you certainly want to do it. Even if you just moved from the city to the country, not a bad idea. The way you're going to drive for the first 30 minutes will be very different.

If you changed your mind about ever using brand X gas, it might be a good idea too. The dealer is supposed to set it when your vehicle arrives because it adjusts for things like barometric pressure and ambient temperature.

The results can be very dramatic, and for some there's been a financial saving. Be prepared for a new 'personality'. There's several threads that discuss actual results.

Here's a quote from a HAPPY MEMBER who tried it. (http://www.ridgelineownersclub.com/forums/showpost.php?p=565604&postcount=19).

Man, I remember the good old days when you just cranked the handle at the front of the car, hop in and off you went.

Now you gotta fiddle with these thingamajiggers, put on a seat belts, worry about brandx gas, can't drink & drive, can't wish people Merry Christmas, ect....

You gotta worry about all of that in Canada? Wow, what a country! :act024:

You can wish me Merry Christmas any time.

Thanks for all the info to date.

Not to worry. :)

From what has been posted here, when you do get your Ridgeline (guessing you're looking for a late-model from your ROC profile), you won't have a lot to worry about.

If the previous owner drove mostly in another region of the country, you might want to have a mechanic do the "idle learn" procedure so that the engine is recalibrated for where you do most of your driving. (Personally, I wouldn't bother unless the RL seems like it's running rough or burning way more fuel than the 15-20 mpg that most of us get.)

But, the only thing anyone has been able to turn up so far about "learning" based on your driving habits is braking, and that resets itself each time you turn off the ignition.

So, don't worry, be happy, and let us know when you find your truck!
