This checks if something is draining the battery when the car is off, and requires a multimeter that can measure amperage. The draw should be less than 50 milliamps (0.050 amps). A reading higher than that indicates a "parasitic drain" that needs to be tracked down.
If you need specific wiring diagrams, sensor values, or a step-by-step test procedure for your , please provide it.
If the alternator isn't charging the battery, the voltage will drop, setting the code.
