You're on the right track, the MFT just sends the command signals to the RCCM module. The software in the RCCM module commands the system on what to do. Ford is trying to balance the attributes of climate comfort with the annoyance of the fan noise. They figure (based on years of customer feedback) when it's not that hot out, people get upset when the fan is really loud. It's not a lack of attention to detail, it's actually too much attention to detail. Personally I can't stand the noise of the fan on full speed (in any car). I'd much prefer it to take just a bit longer to cool down if it can do it quietly.

Nope, I've put the same card in multiple vehicles. Works every time.

I've mixed multiple Nav cards among multiple vehicles and never had a problem. How could you ever get an updated map if the vehicle were locked into one card? To the OP, just like any other part on your car, you can always get one from the dealer.

Which fan are we talking about? The big one behind the radiator is directly tied to the A/C system. A/C system pressure is one of the key inputs on the table that determines fan speed. The climate blower fan (the one inside the dash that blows the air on you) is also indirectly related to the A/C system. If you force A/C off but leave the fan speed on auto, it will increase the fan speed to try to compensate. Gas mileage is a good reason to turn it off, extra wear is not. In fact generally an A/C system needs to be run to keep itself lubricated and avoid drying out of the seals. I'm not 100% sure about the Edge system, but on other Ford systems the A/C compressor is automatically cycled and purged at every start up just to keep the fluids circulating, though this is not related to the OP's original issue.

More likely because the way engine's are controlled to such a fine degree these days, any disturbance in the fuel supply could cause hiccups, stumbles or other issues. I don't know why anyone would want to put fuel injector cleaner into a 2011 vehicle, might as well take your dollar bills and throw them out the window as you drive down the highway.

It remembers sensors. What most people don't realize is that while driving, the sensors are not continuously broadcasting. They only send out a signal about once every 2 minutes. If you're driving in heavy traffic, the car is probably picking up TPMS signals from all the other cars around, it could see 10 or even 20 signals from other cars before it sees it's own signal again. That's why it takes so long to set a fault when there are no sensors, because it's counting to probably 10 instances of not getting the signal it expects, but that could take 20 minutes! As I said, I know for a fact that the system will learn one new sensor if it picks up the other three. I also know for a fact that US vehicles will not learn all 4 new sensors at once. The only thing I don't know is if the Canadian vehicles have the ability to learn 4 new sensors. There is no unique Canadian documentation in the service manuals, they all just say that new sensors must be trained.

Two separate situations in these two posts. First to Theakerr, if you're winter tires don't have sensors, then your car is not learning anything. When you put on the winters it takes a while for it to recognize that the sensors are not there. This is done intentionally so that interference and such that could cause it to miss signals doesn't trigger your warning all the time. But it never forgets the original sensors, so when you put on your summers's again, it just finds them again and is happy. Now to AXCL, there is no "second set" of sensors in the system. But what's odd is that over on the Fusion forum, a bunch of other Canadians have noted that they can change to winter tires and it will automatically learn the new sensors, while Americans who try the same thing do not have success. I was told by a real Ford TPMS engineer that even the US systems can automatically learn just one new sensor, but maybe the Canadian ones are programmed to learn all 4 new ones. This seems at least partly plausible since TPMS is not federally regulated in Canada and Canadians are far more likely to use winter tires.

Considering how bridges in Montreal hold up, Ford is probably just being pro-active. In a couple more months it will be accurate again...

Man, this guy gets all upset about the "GPS transmitting" info, yet GPS devices don't transmit anything, they can only receive. So putting a black box in your car by itself doesn't allow anyone to track anything.

Agree the lack of a frame is not part of the equation, but the shorter wheelbase certainly is. A longer wheelbase can almost always be made to ride better. However that's not really the root of the problem. The Edge was designed to be Ford's "sporty" SUV", with a powerful engine and sharp steering. It's based on a Mazda chassis which was also originally designed for sportiness. That means low recession rates in the suspension, small bushings and aggressive suspension geometry. All of those are things that will hurt the ride and no changes of tires or shocks is ever going to overcome that. Having said that though, there is always some improvement in ride when you switch to lighter wheels. I noticed a pretty good improvement in my Focus when I changed to aftermarket wheels that were 7lbs lighter each. So given that your tire shop has been good to you, see if they can give you a good deal on some wheels that are lighter. I wouldn't bother for less than 5lbs a wheel though.

The F150 also has 4 adjustable cams (TiVCT) and the others only have 2 (iVCT). Also the F150 has completely different turbos.

If it says "Information" then they provisioned the APIM incorrectly. Take it back, it's not the Nav card, I guarantee it. There's no replacing the APIM "chip", they either replace the whole module or nothing.

Not true, the SD cards can be swapped from one car to another at any time. Don't know about the copy protection though.

What makes you think things weren't cleared up? Ford's been testing this software in vehicles since November and I can assure you there were LOTS of things that were cleared up. But as akirby said, at some point you have to cut and run.

There is, but there are only a handful of people, not even dealers, that have the tools to change it.

False, the max pressure is the max COLD pressure - it does account for temperature increases. http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=196

While 44 psi does seem awfully high to me (and I used to work as a tire engineer), without even knowing which model or size you have, it would be foolish to jump to conclusions about the safety of the setup. However it's almost certain that running a lower pressure will improve stopping distance and probably handling as well. But it's also worth noting that even when you've properly trained the TPMS, it will still be calibrated to the original target pressure of the OEM tires. So it's not going to give you a low pressure warning until a tire gets down to about 25psi, which is a long way from 44! So make sure you regularly check your pressures with an old fashioned gauge.

Been out for a week, but I think you're confusion is because Ford integrated the yaw sensor into the RCM module, which also has the accelerometers for the airbag. those used to be separate sensors but are now integrated into one module, located in the middle of the vehicle. The steering wheel angle sensor is still a unique part installed on the column.

Steering wheel angle sensor and yaw sensor are two totally different parts with totally different functions. However if either one of them has a problem, it could explain the issue. Does the traction control light in the cluster come on while the incident is occurring?

Heated only seats always have 2 settings, heated and cooled seats have 3 settings.

Glad you're feeling better about it. As akirby pointed out, the PTU is just a mechanical connection. It does not serve as a differential or have any form of coupling in it. It's just a set of gears that connects the output shaft of the transmission to the driveshaft. All the work is done in the RDU at the back. However the PTUs can get very hot if the AWD system gets a lot of load, such as towing through a twisty mountain road. Just one pass through such an event can heat the lube to the point where it degrades, which could lead to a failure in the long term. So without knowing for sure how your vehicle was used before you bought it, it's not quite fair to blame the failure on poor quality. And since akirby is such a stickler for correctness, I will point out that it's not the PCM that controls the torque to the rear, it's the AWD control module. The PCM just produces the torque, it doesn't know where it's going. The AWD module uses a lot more input than just wheel slip. It uses throttle position, yaw, steering wheel angle and vehicle speed among other things to determine the torque distribution. Availability of the RDU doesn't surprise me. Ford is absolutely maxing out it's suppliers (Linamar) on the production of those PTUs since the Explorer has been such a success. They can't even get enough parts to the plant to build cars - the Oakville plant was recently shut down for 2 days because they couldn't get any PTUs. So having a large inventory for service isn't going to happen!

Not really that easy. There is Nav software in the "SYNC" system, which could be updated, but the fundamental "switch", ie is Nav turned on or not, is more or a hard-coded thing and doesn't change with software updates. Also the cluster has it's own software that is different between Nav and non-Nav. It's my understanding that the cluster could not be updated with the USB, just like you can't update the PCM code with a USB. That being said, it is still possible to change a non-Nav vehicle to Nav with only software - I've seen it done. But as akirby points out, it's just a matter of marketing.

You could always acquire one legally from navteq.com

Unfortunately it's a very tricky job, even dealers were not able to do it right the first time. I would not attempt it as a DIY and I wouldn't even recommend going to anyone who hasn't done the exact job before, unless they give you a guarantee that it will be done right or they will redo it for free.

So are you saying that when they recalibrated the sensors, it accepted all 4 sensors with no problems? My first guess would be to try to recalibrate them again, if you have a bad sensor it won't recalibrate.
