My car is draining the battery and the only thing i see wrong is that when i put the car on park and turn off on the display it shows a "shift to park" im wondering what is wrong any help is apreciated.

 

If the BCM does not see that the car is in PARK,, it will not properly go into sleep mode.

You need to figure out what is not telling the BCM that the car is in park.

 

Yes im trying to figure out what it can be but have no clue im still looking .

 

what year car? do a search on this forum as this has occurred quite a few times.
good luck

 

You need to get the service manual if you want to start diagnosing this yourself. I do not have an automatic but I would expect that there is a contact switch near the shifter that closes when the car is put into Park...it may be that the switch is in the trans itself. The manual will tell you where it is and it would be the first thing I would check. Until this is fixed, you need to keep the battery up and not let it be drained or it will be damaged.

 

I believe that its a function of the selector switch on the transmission. I dont have my ESI installed so, I cant check.
