In a 2012 Acura TL, if the check charging system light comes on, it means there's an issue with the electrical system, possibly the battery or alternator. Start by checking the battery's voltage – above 12 volts is good, below could indicate a problem like a bad cell or needing a recharge. While the car is running, the alternator should charge at 14.4 volts. Any deviation from this could signal a problem with the alternator or voltage regulator.
