What would i need if my abs light is on ,on my 97 chevy cavaliar
I think you need System Scanned for Codes. This detects the car's problem to a computerized gadget, and then sends the signal to the ABS. So if the ABS is on, just make sure you repair the code so as the ABS can shut off.
Nothing, it's telling you your anti-lock breaks are on. Edit: that's what it meant in my car, but if you want to be sure, take it to autozone they'll let you know.
