Where is the battery located... b/c i'm about to put it in storage on sunday.. b/c i'm going to IRAQ FOR 15 MONTHS.. SO I SHOULD TAKE THE BATTERY LOOSE RIGHT?

From a safety standpoint, the closer to the battery the better because if you run a power cable to the center console and it is not fused, any short in it will cause a disaster.

Can someone scan it for codes ? Pending codes may not set a light .

Disconnect the battery, that is all.

First, a bad battery doesn't turn the light on. Just A bad alternator or ECM. Start the car. put a volt meter on the + and - sides of the battery. If it reads 12 to 15 volts (closer to 15 for a new alternator). The alternator is good. And is charging. The problem is the wiring or the ECM. It can be bypassed to turn the light off. I just did it a week ago. Problem is , I don't have the wiring diagram for your car. Don't get a book from the parts store, it won't tell you. Go to alldata or Mitchell and purchase a manual. It's online and lasts a year. But they give you good electrical schematics...

After 3 months it is possible the fuel pump has seized up due to the fuel going bad. As of 2 years ago, fuel has a storage life of around 90 days. If the fuel had ethanol in it when it was stored, this fuel stratifies in the tank and the water content sinks to the bottom also ruining the in tank fuel pump.

It is also possible other components may have failed coincidentally and you will need a scanner to pull the codes stored in the ECU to see if other sensors have failed.

When electronic loaded vehicles sit until the battery goes flat.... it induces a lot of false codes as the system awakes and then goes back to sleep because of low voltage fluctuations as battery looses it's voltage.

The ground clamp should be removed from the battery before late model vehicles are put in long term storage to prevent electronic code scrambling .

yes it is possible

typical problem of an shut alternator. the voltage regulator bridge of the alternator is not working properly. only solution is to change it. if youu smell rotten egges when car is running thats it!

is it an auto or man?

a good battery will hold a charge through the winter if disconected from the vehicle adn left fully charged.
you may want to look into a battery monitoring charger, it is a trickle charger that is designed for long term use, it monitors battery volts and turns on when needed.

also put carpet squares or cardboard under the tires if you are parking on concreet. this will help prevent dry rot and flat spots

e fuses to be sure. If your battery had lost its charge while you were away, you may need to put in the code (if it has one).
