try taking neg cable off for about 15 mins then hook it back up. did you take it and have it checked to see why it's on? because autozone does it for free they can also reset your check engine lite.

remove negative terminal from battery, give it 3-5 minutes, then remove positive terminal from battery, then give it 15 minutes. then hook battery terminals back up.
this way lets the memory in the ECM totaly discharge to clear the codes.

you don't have to remove both cables to reset computer you just take neg cable off for about 15 mins. and when you ever have to replace battery always take neg cable off first.
