That would be traction control, it kicks in when when on slippery surfaces, in some models you can turn it onor off with a button on the shifter.
More the likely the alternator has quite working are the belt / belts have broken on the front of the engine.
These codes can be caused by aftermarket scan tools and also by unpluging the scan tool with out turning the key to the off possition.
generally that you have an electrical issue, either your battery is dead or dying, or it could be your alternator also... make sure you have booster cables in your vehicle
