My battery just started dying and I have jumped it three times.

Now my TCS light is on and won't go out in addition to the ABS light on and the battery not stayting charged.

What in the world could this be?

Is it the alternator or just a battery issue?

 

Well for starters i would go somewhere like batteries Plus or any auto parts store that can load test the battery and see if its good or not. Once you address that problem id move on to the next.

 

Well, I hate to state the obvious... but maybe you should replace the battery instead of reviving it again and again and then let's take it from there.

 

Computer controlled vehicle, fuel injection systems, electronics galore, these cars will not run without full battery power. The free check at any auto parts store is the thing to do. It will tell you if its battery, alternator or both.
If the battery is more than 5 years old, expect to replace it. See threads about radio code and battery replacement

In the meantime, no use of lights, fan, radio or non essential electrical will help on the way to the parts store. It is always better to charge the battery slowly with a charger than hit it with a big charge when its empty.

Everyone please remember, jumper cables go POS on dead car battery, NEG on a metal ground point NOT to the neg terminal- if there is a serious problem in the electric- you will not damage the car with the good battery, Then hook up pos to good battery and last neg to good battery. Let it run a few/several minutes with the GIVING car at high idle-1500-1800 -that will ensure lots of juice thru the cables

Think safety first, the Life you save could be your own
