Not the fuse,I reset ECU twice does not work,my mechanic told me there is power to the multi-function control but does not sent signal back.
Another question "what will happen while driving with KEYLESS-GO suddenly the battery gone dead" Is the engine will shutoff?

CAR BATTERY ITSELF might be the problem,about a week later the battery will not hold charge I went to auto parts store to have them check they said the battery was fine,I change new one anyway.....EVERY THINGS COMEBACK ON

That's weird. If the battery was juicy enough to start the car it shouldnt affect the steering wheel functions.

I had the opposite problem. My car sat in a parking lot for nearly 8 months before I bought it. The battery was dead, it wouldnt start but all the functions including keyless go worked fine.
