YOU NEED TO ERASE TROUBLE CODE WITH A CODE SCANNER.IF CODE HAS BEEN ERASED AND WARNING LIGHT STILL APPEAR MAKE SURE ALTERNATOR BATTERY POWER FEED WIRE AND CHECK WIRE COMING FRONT SAM CONTROL MODULE WITH FUSE AND RELAY MAKE SURE WIRE IN PLACE TIGHT NOT DAMAGED. CHECK MAIN FUSE IN FUSE BOX THAT SEND POWER TO STARTER AND ALTERNATOR.

well you mait want to check the Car generator is is working or not beacause if is not you can still buy new battery and they still will not charge and the will day and the light will be off
