what could be wrong?

[max77]

I have a VS commodore series one, the car will run but only for a short period of time, as soon as it is turned on the battery light switches on, after a short distance the Engine light and ABS light turn on, the car will continue to stay on but it loses its responsivness. What could it be?

check that it is charging
failing that pull codes from computer
