I read somewhere that if the vehicle does not have power for a certain amount of time a lot of the sensors need to be re-learned. How long is that time?

 

A better question would be how long you intend to leave your battery disconnected?

I've had mine out of the car for two days with only minimal adjustment. I don't know which "sensors" you're speaking of.

 

If I remember correctly (it's been a while) I lost clock, seat presets, radio stations.. That was it I think.

 

I'll see if i cant dig up the page where I read that at. I dont need to disconnect for long, few hours at most. Just dont feel like bringing it in again. i had to bring it in and get the idle re-learned last friday.

 

Im not sure but I had my battery disconnected from the car for about a month and a half while I was away. It started right back up after I reconnected it. But I left it running for 20mins after I came back to warm up.

 

A few hours will not cause you a problem. Go for it.

 

I changed my battery and lost radio presets, but not xm presets.

 

If you mean the supposed relearning your driving style I think some people say a couple of hours and others say a day...

 

For ecu reset It is recommended at least 12 hours.

 

I always disconnect my battery for the winter because I don't drive it.I'll have it disconnect for about a few months at a time.everything will reset radio,milage not the milage on the car just the milage on your A and B trip.I've never had a problem with it.I'll start it up every week just to get everything running for about 5-10 minutes.

 

JUST DO IT!!!!..........(nike) :P

 

2one8, you must have understood by now leaving your battery disconnected will not hurt anything other than clock and radio station reset....happy trails.

I had it disconnected for a few hours and its running fine.




this is where I read about disconnecting the battery...

"Whenever the throttle actuator is replaced, disconnected or the battery is disconnected for a certain period of time, this electronic throttle module will either need to be recalibrated or relearned in order to keep the idle speed at a specific range."

I had it disconnected for 2 days didint have any problems.

 

If you leave your battery disconnected for more than 13.4 minutes your vehicle is likely to explode.

haha just playin man... doesnt really matter how long its disconnected
