Could just need a simple reset of the computer. You may have to have a mechanic hook up a computer under the dash to do this.

Usually you can just disconnect the negative battery cable for 10 mintues or so and it will clear the code out.

My battery light has been coming on and off for a couple of weeks now and saying "Service Battery Charging System".

Have your charging system tested. The battery light is turned on when there is a charging system problem causing an over/under charge condition. You may possibly have an alternator problem. If the battery is not being charged properly, the computer will start shutting down electrical components for protection and to keep enough voltage supply to enable the vehicle to continue running

Sounds like a bad alternator. GM vehicles are notorious for failing starters, alternators and fuel pumps. If your battery light is flashing, your alternator is not putting out enough keep the battery charges and keep all of those electronics running. take a volt meter. You should get anywhere from 13.8 to 14.8 volts with your engine running and about 12 volts with everything off. Take the vehicle to your local auto parts store for a free charging system test. Advance auto parts can load test the battery and charging system.

Take it to a shop or auto parts store and have the alternator output checked, it may not be producing enough amps at idle to keep the electrical system properly charged. Please rate this answer, thanks.

The "service charging system" message


" service charging system ", means you have an issue with your battery, your alternator, or
your voltage regulator. Something is causing your battery not to charge properly. You should
have it checked as soon as possible. This could keep your vehicle from starting next time.

I hope this helps you.

My 95 aurora has a message on dash that says check charging system. the car stalls while running a while. idling. what could this be?

check battery voltage with multimeter while running across battery posts. should read 14.0 volts there about. if it reads battery voltage (12.0-12.5), suspect alternator failure. also check accessory belt and idlers,etc.
