By This article will explain the meaning of “service battery charging systems” on your Acadia. I’ll also give you some common causes that I have experienced and show you how to fix them.
What does “Service Battery Charging System for GMC Acadia” mean?
This message is a simple indication that your GMC has detected an issue with the charging system, which includes a battery and alternator, as well as wiring and an electronic control unit.
This message appears on the Dashboard when the system detects a voltage problem in the battery.
What causes the “Service Battery Charging System Fault” on a GMC Acadia
After I’ve explained what the fault message on your Acadia means, let’s take a look at some of the most common causes from my own experience as an automotive technician.
Failing Alternator:
This message is usually caused by a failing alternator.
The alternator generates electricity to power your vehicle. This is done by spinning a magnet within the alternator using the GMC’s engine. The current generated can be used to power your accessories, electronics, and battery.
The alternator will eventually fail and cause problems with the charging system.
I recommend you test your Acadia alternator. A good alternator should show 13 volts or more.
It is best to have the alternator repaired or replaced if it shows less than 12 Volts.
Bad Battery
A bad battery is another common cause of this message. A battery is an energy-storage device that provides power to the electrical system when it is needed (starter motors, fuel pumps, etc.). ).
When your battery fails, it is not able to supply enough current to these components causing them to fail.
The ECU will display “service battery charger system” if it detects a problem in your vehicle’s charging system.
GMC recommends changing the battery in your car every 3-5 years. If it is older than five years, then you may want to consider replacing the battery.
Check the alternator first if your battery is younger than two years.
Disconnect Battery Terminals
It is easy to overlook, but I’ve seen many GMC owners come into my shop with loose battery terminals.
The message Service Battery Charging System Fault can also be caused by loose or corroded battery terminals.
You should inspect the battery terminals to ensure they are secure. Use an electrical contact cleaner on the terminals to remove the corrosion.
GMC Acardia Charging System Failing Signs
There are many other signs that your charging system is failing besides the obvious message on your Dashboard. It is possible that your charging system isn’t working properly if you experience any of these problems:
- The headlights of your Acardia are dim or flickering
- The battery is not holding its charge and must be charged frequently
- The alternator making unusual noises
- The vehicle may have difficulty starting or occasionally stall.
How to diagnose and repair Battery charging system problems in GMC Acadia
You can fix the fault message by following these steps:
- Test the Alternator: If it is defective, you should replace it. The next step is to test the battery to see if the alternator passes the test.
- Replace the battery: If your alternator is working well, but the battery is not, you should replace it. Check all the connections to make sure that they are clean and that the alternator and battery both pass the test.
