I have had this car about 1 month. 2 weeks ago, the automatic up/down window feature stopped working. I did the procedure listed in the manual to re-enable it.
Now today the Nav system is requesting the 4 digit code when I start the car?
Is this something I am going to encounter several times (or more) per year???
What could be causing this?
Thanks,
David |

Sounds like the battery is disconnecting from the electrical system sometime after the key is removed. All your symptoms can be caused by such an event, no matter how momentary.
One hopes your dealer has a skilled electrical system troubleshooter. Who knows, the solution may be as simple as replacing the battery. Let's hope so! |

| the automatic reocde number is on one of the forms that the dealer might have given to you so find it and keep it well because you need it most of the time. |

| Yup, sounds like some sort of a battery connection problem. |

I have this problem too. My windows have had to be reset about 5 times in the past 4 months, and once the NAV system had to have the code re-entered. We all understand that this is an intermittent power issue - but has any one had this specific issue on the Pilot found the cause of the momentary power loss, or been able to faithfully recreate the problem? I took my '06 in for service today, and they checked the electrical system and pulled out the radio to check for bad connections - but were not able to find anything wrong.
Thanks in advance to anyone who can help. |

I've also had this issue on my '06 EX-L. I've owned the car for just over 7 months and the nav has reset twice and the auto up/down many more times. But, the two events seem to be independent of each other. Of the two times the nav reset, the window programming was undone once. The dealer replaced the nav and that seems to have cured the nav resetting (for now). But, the window resetting is still happening. I have an appt this Tues for them to again take a look at it.
While a minor issue (it certainly doesn't affect the safety of the car) it's very annoying!
Good luck to all of us!

Humm, had my '06 since January and the NAV/Radio had reset ONCE. The Windows has not happened yet...
Seems there might be an electrical problem looming in some of these Pilots...
Has anybody talked to the Dealer regarding this yet??? |

I hopped in my Wife's car at the boat ramp yesterday and the NAV came up asking for the PIN number. I tried several numbers that were on stickers and cards, finally finding the right one and it booted up. I called the dealer, who said he had never heard of this, except with dead/disconnected batteries. I referred him to this site and suggested that he read it.
Her car has also had the sound system blank out two or three times and come back on by itself.

Speaking of the window vs. nav issue... One may be more sensitive than the other in regards to power failure.
For example, consider digital clocks in your home when the power blinks (microwave, alarm clock, etc.). When the power blinks, some go out immediately while others can take almost 5-10 seconds before they are affected. It has to do with the number and size of capacitors built into the component.
For the record, I think it is odd that Honda doesn't store more of this information in NVRAM so it is unaffected by power failure. |

Some stuff can't be stored in a eeprom or flash memory location if the amount [total number] of "writes" is substantial. The memory locations actually wear out after a certain number of writes. The flash memory is good if you are storing data that is accessed often, but "written" relatively seldom.
We have to be very careful not to accidentally write to one location or it will fail eventually.
RAM has no limitations on the "Writes".

Well, that is my point. The NAV ID seems like it can be written once to a non-volatile RAM location so that it isn' t easily lost on battery failure.
This also seems true with the window auto-down setup.
I think it was a poor design decision to allow this loss of settings when power is lost. |

The Nav system isn't losing it's ID, it's the security code that needs to be entered after a power disconnect. They do this for security reasons. If the unit should be stolen, then the thief couldn't use it without that code. That's why it's also a good idea to not leave the radio/nav security code in the car.
And, you should notice that none of the radio/nav settings are lost after a power disconnect. It still remembers all of your radio station pre-sets and the address book on the nav is also all still there.

The window resetting I would guess is to allow faster installation of the assembly in the factory. They don't need to get it set exactly right. Then when the car arrives at the dealer, they then "tell" the window where the max open and max closed positions are located.
But, of course this is just my opinion :).

I took my '06 in to the dealer (Stevens Creek Honda in Santa Clara, CA) today for them to look at the window resetting (becoming unprogrammed) and they called the "Tech Line" and were told to replace the "power window control unit and retest." The don't stock this part and have ordered it.
So, it's not solved but they are trying! But, even after they replace that part, it'll be a while until I know if it's truly fixed since this doesn't happen on a regular basis.

I had both the Window and NAV problem. Another Pilot.org user told me that he had the same problem and noticed that the box on his fuse cover was loose. He opened it, pushed down on all the fuses and has not had the problem reoccur. I opened my fuse boxes and removed/reinstalled the fuses. I'll have to see how it goes, but up to now the problem has not repeated itself.

Yep that was me. I picked up the car and within a couple weeks I got hit by the auto up/down window feature not working. I reset it and it worked. Then a month later it did it again. I was looking at the engine compartment and noticed that the fuse box cover was not fully closed. I opened it and pressed down securely on all the fuses. A couple were only 90% pressed in. Since I did this, I haven't had any problems... |

When I converted my relay distribution panel to make my rear power outlets constant hot, I went through and pulled/replaced the fuses that fed the Nav/Radio, just to see if that might alleviate the reset problem.
The jury is still out, since it was such an intermittent problem.

| I just had ther Nav Code thing happen to my '06 EX-L and we've only had it for 5 days. We'll see if it happens again. I checked the fuses under the hood and all seemed fully seated. |

I just picked up my '06 from the dealer after they replaced the, "CONTROL UNIT, L. POWER WINDOW" (part number 72256-S9V-A01). It's way too soon to tell if this fixes the problem but at least they're trying. I'll give it a month or two. If the window doesn't reset in that time, I'll call it fixed.... for now :).
So, how do I now find where that part goes? I can find it on some of the on-line parts places and see the part number and price. But, how do I go from that to the exploded parts diagram to see where it's physically located?
Thanks!
Larry. |

| MDX owners are also reporting the same nav code re-entry issue. |

| So much for the fuse box theory.....my 06 EXL NAV reset the auto window feature.......again!!!!! |

| My window wigged out this week aftre about 2500 total miles. I'll reset it and see how long it stays. |

Well, it's now been almost a month and I've been reset free.
But, not one answer to my question about how to go from a part number/description ("CONTROL UNIT, L. POWER WINDOW" - part number 72256-S9V-A01) to where it's physically located in my car. I've looked at on-line sources and in my service manual and I'm obviously missing it.
Any hints?
Thanks!

When I was putting in new speakers and some sound deadening I noticed a small (4"x4" maybe) module connected to my driver's side power window plug. It's only on the driver's side and if I remember correctly it was labeled something similar to what you're looking for.
If you remove the driver's side door panel you'll see it. I believe it is on the outside of the vapor barrier kind of towards the lower/middle/left side. |

My Wife just informed me the CD/Player/Radio did not boot up when she started to work this morning. The displays were normal but there was not sound until about 5 miles down the road. It was cold here this morning [58 degrees] so temperature might be a factor.

While 58 degrees is cold for Florida it is nowhere near cold for a car. Most of these guys in Canada I'm sure are seeing well below freezing with their Pilots.
I doubt temperature was a factor in your radio's hiccup. |

| On my 2006 pilot, the nav and radio codes are stuck to the side of the glove box nearest to the driver. They can be seen whent the glove box is open. I found this out when the nav unit wanted the code number to reset and I happend to be near the dealer and the tech came out and opened the glove box and punched in a few numbers. The codes are not labeled with names but are in a string of numbers on what looks like a factory label. In my case you can recognize which numbers you might need beacuse the radio code does not have a number above 6. |

Honda has been trying several things (on different service trips) to repair this problem.
1) Replaced the battery (did not fix the problem)
2) Replaced the controller in the driver's window (window problem has not returned, but NAV still requests code from time to time).
3) Replaced the NAV unit ( did not fix the problem)
4) Checked power/grounds and found a loose ground that they fixed. Just had this done last week, so we'll have to see if they found the root cause
------------------------------------------------
6/11/07 Update
Since the loose ground (not sure where it was) was fixed the NAV has not asked me for the code.
The driver's window needs to be reset again, so there still seems to be a problem with that circuit however. |

Do you know where they found the loose ground?
