How To Use the iLAND App Engine and Transmission Adaption Reset Demonstrated on the Discovery Series II. Hi I'm Doug. Your tech support representative here at Atlantic British. And in this video we're going to talk about adaptions. Or better yet, clearing adaptions. What adaptions are is the control module for the engine and the control module for the transmission. As you drive the vehicle, will adapt to changes in the sensors, changes in your driving habits and essentially adapts to keep the vehicle within a certain efficiency level. So what happens is, should you develop a fault, like a mass airflow sensor or a transmission shift fault or anything else that will affect the drivability of the vehicle. After you've done the repair you need to clear the adaptions. Now I'll just quickly explain in the case of a mass airflow sensor, mass airflow sensor has deteriorated, so what happens is the system has adapted and constantly adapted until it's reached a certain limit it can no longer adapt. And you basically get your fault code. And you have to do a repair. You put the new airflow sensor in it, and what happens now is that's reading correctly, but your still running off the old adaptions and the cars going to run worse than it did before you did the repair, and you're going to think that's not the problem. What you need to do, any time you change O2 sensors, throttle body, throttle position, mass airflow sensor, you should always clear adaptions. So what we're going to do is we're going to show you how to do that with the new iLAND and how easy it is to do. And it's also very important so keep watching. Alright, so you now the basics. You're going to plug your iLAND in. You have your dongle that you plug into the diagnostic. You go through the basics and then you're going to go to this screen. Now on this screen you'll notice all the vehicles, all the blocks, are in the red. This is because this is the Pro series and we have access to all these different vehicles. If you've purchased an iLAND, you can get for just 1 design vehicle, like in this case say Discovery, it will be just red block on Discovery, the rest will be in white. So we're going to pick our Discovery, We'll go through what the call garage disclaimers. It's telling me we're in the current version, otherwise it would list another version underneath and we would load that in just so we know that we have the latest and the greatest. We'll hit confirm. And it's going to connect with the Bluetooth. And just give it a few minutes or a few seconds actually. It doesn't take that long. Here's our choices. We can go to any one of these Discovery versions. We're in a 1999 Discovery 2. And we'll go to engine. Now essentially all the Discovery 2s are going to be BOSCH motronic. No other system. That's basically the only petrol system they used on these with the 4.0 and later on the 4.6. So we now the ignition is on. The keys on, we can see our lights. Now you've got this listing of all the capabilities. But we're going to go down to vehicle maintenance. Gives you a little warning as far as looking at who should be working on the vehicle. Now here we have reset adaptions. This is very easy where we're going to hit that. It's going to sort of explain what adaptions are. And under what conditions you should be doing this under. Like say basically fuel injector. Lambda sensor, which is essentially O2 sensor. Fuel pump, mass airflow sensor, intake manifold leak or air leak repair. All that can affect adaptions. So then it's going to ask you at the bottom, basically confirm do you wish to reset ECM adaptions. So we're just going to do that. And they've been reset. Just that quickly, just that easy. But now what it has done it has reset all of the initial setting for the ECM back to original factory settings. So we hit OK. And we're all done with that. Then we can back up. And it's usually best that if you do one you should always do the other. It's reasonably easy to do. Just get this to back up here. Maybe it just doesn't like that finger. There we go. So we're back to part of our menu. We're going to go back one more. Ok. So now these are all the different modules we have access to. So we're going to go to auto gear box. Essentially transmission. Ignition is still on. It's going to reconnect. Ok. So now we've connected with the transmission control module. We'll go to vehicle maintenance. We hit Ok. And there right on top is reset adaptions. And we'll hit that. Then again it's going to go through and explain why you would do this and under what conditions. And then at the bottom of course there's your confirmation do you wish to reset ECU adaptions. We'll hit yes. And there you go. Adaptions have been reset successfully. So now we've done both engine and transmission, it didn't even take 5 minutes. So now we'll back up. We'll get back to the main menu. And then of course when you go to do this it will say really quit. We're going to back out of that. And at this point it is a reminder make sure you don't leave the dongle plugged into the diagnostic plug. And we'll hit Ok because we pulled it out. And that's it. That's basically a very easy thing to do. Especially with the iLAND and it's very important to do as you can see under certain repair conditions so that you know when you're done and you restart your vehicle it's going to run right. So, if you're going to get into repairs on your Discovery 2, again that's 1999 to 2004, and you find you need a tool that's going to be able to do the reset for adaptions just give a call to any of our knowledgeable salesmen at 1-800-533-2210.
