Hi. Yes, in a lot of cars when the battery is low or the charging system is malfunctioning, the ABS Light, Brake Light and the Traction Control Light will come on. This happens because these systems must have the correct battery voltage for them to operate properly. These lights coming on is just another indicator that the battery or charging system needs to be checked and fixed so the car will operate properly.

I suggest you have a certified technician, such as from YourMechanic, come to your location to replace your alternator and check your car for any other issues.
