thanks man....i just noticed the alternator is bad..i took off the negative terminal and as soon as i take it off the car shuts off..i also noticed my windows having a hard time going up and some lights were not coming on..
Wait, how did you notice the alternator was "bad"? Unless you have it tested, there aren't any obvious tell tale signs that it's not operating to capacity to the untrained eye unless it's on fire. If you disconnect the negative battery terminal, you have disconnected the electrical system in addition to the battery. My guess is that the shop your car was in, never bothered to put your car on a battery tender or disconnected your battery while they were working on your car and just let the battery deep cycle (drain). Derrick is right. Let your battery charge to full capacity and clear the codes. If that doesn't work, have your battery load tested and then have your alternator tested.
thanks Tim, i went thru that thread and it didnt have the codes i was looking for....
what i did was get on the phone with my mech and he told me to check all the connections to the alternator and bettery to make sure there was anything not making contact.. i did it and everything looked perfect. so he tell me my next option was to disconect the negative terminal from the battery while the car was running, the car should stay running on the alternator if it shuts off it means that the alternator is not recharging the battery.
i did what derrick said, to fully charge the battery and clear the codes.... as soon as i clear the codes the pop up right back right away.. the battery holds the charge but the car drains it again when i drive for a long time..also the battery, ABS, BREAK lights are not going away with a fully charged battery..
I've seen that happen after the battery has been jumped because it's low. Maybe that's the problem...

ok, so i get my car from the shop from getting my front bumper painted.. as im parking my car i noticed the battery-ABS- Break light symbols were staying on when the car was running... i also try the cruise control button and it would not light up on the dash how it usually does... so i get it check out and im getting these codes..
