Before you get into the details, you must understand what actually does the service battery charging system mean in a GMC Acadia/Terrain/Yukon. These are the most common models of GMC that are prone to get the issue within.
Electrical components of your vehicle need electrical energy to operate through. Those components get the energy from your vehicle’s service battery charging system.
When there are issues in your vehicle’s battery charging system, it shows the error message on the dash, or a Red/Amber/Yellow light may appear on your screen.
Let’s explore why these happen and how to resolve the problem.
Power Loss Of The Battery
Power loss or low voltage of the battery is the most common reason. When your battery is old, and there isn’t enough juice left, it loses its capability to work, and the components that run through battery power don’t get the energy to run.
Solution: When you’re facing service battery charging system problems, test the battery first. For that, you’ll require a Multimeter. You can get a Multimeter at a meager price in any auto store or online.
Generally, battery power below 12.6V means your battery is the issue. Most of the time, the battery is checked while turning on the vehicle. The best way to check the battery is by checking it both in on and off condition.
When you see the voltage is slightly below 12 Volts while your vehicle’s engine is on, it doesn’t necessarily mean the battery requires attention. Recheck the battery when the engine is off. At this point, if the battery is running lower than 12.6Volts, it’s time to replace the big boy.
A faulty alternator is the second most important thing to check when you see the message.
Solution: Examine the cables of the alternator if they’re firmly attached or not. If they are, then check the pulley belt that spins the pulley. Wear or tear in that belt resists the pulley from spinning.
In another case, the belt may be fine but still not spinning the pulley. So, you’ve to check this component deeply.
Blown Out Fuse
If your Battery and Alternator components are all fine, then a blown-out fuse could be the problem.
Your vehicle contains a lot of electrical components. When you’re operating your car, there are supplies running currently. There are fuses located for different electrical components to ensure their safety of them in an accident. If there’s something going wrong, fuses prevent the electronic components from being damaged.
When the fuse is blown out surely, it loses its working ability, and that could be the reason for the message. You’ll find the fuse box at the front of your vehicle or on the driver’s side in some models.
Solution: Check the fuses with an electric machine if you’ve it or you can simply check them with the help of a tester. If there’s a damaged fuse, replace it with a new one.
Loose Connecting Cables
After the major diagnosis, if everything is alright, check the connecting cables. Sometimes the problem is just loose, stiff, or broken cable connections. Or, sometimes the cable connection looks fine, but it lacks continuity.
Solution: Use a Multimeter to inspect the cables. When you do it, if you hear a buzzer sound, that means the cables are fine. And if you don’t, that means the wires are defective.
Setting Problem Of The ECU
In some cases, it’s just the ECU showing the message for its own problem. When you diagnose all the components thoroughly and find no problem, the ECU fault may be the reason.
Solution: To fix this, reset the ECU. Firstly, turn off your vehicle and disconnect the battery. Wait for half an hour after disconnecting and reconnect afterward. This process will reset the ECU itself, and you’re good to go.
