Abs, battery, and airbag light on

[JB_Runner]

So it started yesterday my ABS light came on. But once I turned off my car and got back it in to restart it my ABS light was off. After a few miles of driving my my ABS light came back on and then my battery light comes on and off after shutting my 4runner down for a while. And now my airbag light came on. This is my DD and I have to drive around a couple times a day for work and I don't want to break down and be stuck somewhere. Would anyone know what the problem could be?

If you have a multi meter start the truck and see how many volts are at the battery terminals. If its 13.2 (or so) or less your alternator is bad. Abs is one of the first systems to notice low voltage

Yeah, I would check the battery voltage with a multimeter. Make sure it's at our above 12.5v, you can also check if the alternator is charging the battery properly by bringing the rpms up a little and see if the voltage on the battery goes up.
