My steering wheel controls went out about 10 days ago. This happened once before and they came back themselves 10-14 days later as I prepared to take the car in.

Oceans60r suggested "The easy battery reset is to disconnect the negative battery cable from the battery and place it over on the Positive post. This will drain and keep alive memory from any module "stuck" Give it about ten minutes or two beers. Then put the key in the ignition and turn to position II and then reconnect negative cable. You will also need to later lock and unlock the drivers door with the key to reset the power windows and sunroof if equipped."

And, presto, they are back.

He also noted: Reason for the key in position II was that the factory trainer said it allowed all the modules to get power at the same time vs some only getting power when the key is in position II. So it allows the network to boot in order and ping all the modules. It won't hurt anything doing this."

My guess is that they were revived the same way the first time which was around the time I installed my iMIV--and disconnected the battery, I just did not make the connection
at the time.

This car makes me think of my laptop: sometimes you just have to reboot.

I should have phrased the key being in position II allows the correct boot order of the entire network vs the key NOT being in Pos II or not in at all. Only select modules have power w/o the key in II.

I'm glad it worked out for you.
I would suggest there is probably a Software Update for the SWM that helps deal with this. http://********************/smile/emthup.gif
