Interesting Issue after an install
 

Anyone have an issue with the feature that opens your window when you open the door and then closes it when you close the door? I had the AVIC-F90BT installed yesterday and before I could play with everything the shop closed. Well now my Service Engine Soon light came on but the tech insists he didn't disconnect anything, Dealership is looking at that in the morning. Onto the interesting thing. The window opens that 1/2" or whatever when you open the door. It however does not go back up when you shut the door. If you open and close the door a few times it opens the window that 1/2" or so each time so after a few cycles the window is open like halfway. Anyone know of anything that might cause this issue in specific. I mean more in depth of an answer then "the tech did something wrong" would be nice.

Did you try resetting the window motors? (Same process as when you yank the battery cable..)

Perhaps it's somehow confused?

The window behavior you describe is exactly what happens when you disconnect the battery cable and they lose memory. Your owner's manual has the procedure to reset the travel. Basically, get in the car, close the doors, turn the car on (don't have to start engine), push the window all the way down with the window button, then run it all the way to the top holding the button up, and keep holding it up for several seconds after it reaches the top. It should now go auto-down and auto-up correctly, and do the open/close door adjustments. Repeat for other side.

You can confirm battery cable was disconnected to cause this by also checking the service mileages in the little display on the right. It tracks mileage for changing your oil, air filter, etc, etc. They all get reset to zero when the battery is disconnected as well.

As for your SES light: I don't know. Disconnecting the battery shouldn't cause a SES light. It would be a good idea to hook up an OBD-II scanner and read what code corresponds with the light first.

If the install guys claim they never pulled the battery cable, and we're seeing both a SES light and indications of memory loss, it could be that they did something wrong with the wiring to short out or otherwise drain your battery, and this is all from low voltage.

Thanks for the reset procedure I will definitely give that a shot. Dealership should take care of the SES light as less than 500 miles on the car.

So cost me 1/2 hour of "labor" to clear the light and determine why it had come in.

The SES light came in because if you disconnect any connectors, in this case is was the heat and AC connectors, and turn the car on the computer can't communicate with those controls and therefore gets confused. Since it can't communicate it throws the SES light. Therefore I recommend if you have your HU replaced you do it yourself or ensure the person doing it does not turn the car ON without all connectors connected. Cost me $52 for this lesson. Now to try and get that out of the install place that did my speakers and HU.

Speaking of which I will post some pics soon of the install. Got a real nice Ipod mount that looks slick and clean.

Hey man does the SES re-set for the 350Z and other nissan and Infiniti vehicles not work on the 370Z?

Not sure. Car only had <500 miles on it so I was babying it. I just wanted to make sure wasn't a bad sansor or anything. I would assume that the code reader most people have would be able to read and clear the issue. I did get a detailed printout of what the issue was. So now I can potentially save other members of these forums the same headache and $.

i had the same problem when i had my KENWOOD DNX6140 installed. 1st things first. for the SES, disconnect the battery, let it stand for a little while then reconnect it. when you restart your car, the SES should be gone. next thing for the windows. your installer probably tapped into the "computer" of the car or w.e to give your headunit power. atleast thats what the dealership shop told me. what they did was split a wire and ran the headunit from the splitter, not the computer. i paid labor @ the dealership for that. they told me if im going to get stuff done "electrically", have the installer split a wire? just dont have it connected to the computer or w.e? it f*cks with the car or some ****.

but yeah just take it to your dealer and tell them the situation with your windows. good luck

Windows were fixed with the reset procedure :)

Or instead of clearing the SES blindly via the pedal method or disconnecting the battery, you guys could pick yourself up a handy-dandy OBD-II tool at any auto parts store and actually read the codes to know what they are yourself, and then clear them via the tool as well.

I also have the AVIC F90 BT, and have had the same exact problem with my windows since install. I'm heading out to my car to try that "reset" procedure right now...

***EDIT - Window resetting procedure worked like a charm. Thanks Wstar! +1 Rep
