If the voltage is too low a fault code will be set.
System voltage low car.
If for any reason the pcm detects that the vehicle voltage level is too low the p0562 code will be set and the mil malfunction indicator light or check engine light will illuminate.
Hi dan got a 2017 pathfinder battery light cane on car stop moving.
The powertrain control module pcm monitors the ignition feed circuit to determine if the charging system is working.
Perhaps you have seen one of these messages or notifications.
Normally the small battery on the motherboard does not run low for several years but because there are so many reports of this problem on new systems it sounds like mayber dell got a batch of bad batterys.
This is strictly an electrical issue.
Check car battery charging voltage.
A low voltage issue would be caused by the alternator not charging or a problem with the battery.
When the engine is turned off there should be 12 volts in the system and when the engine is running the alternator should charge the car with 13 5 14 3 volts.
You should connect the voltmeter to the battery as before but not the charging voltage and this should be done after charging the battery or jump starting the car.
There could be a problem in the charging system.
13 5 to 14 5 or more volts at idle should be produced by a charging system that operates normally.
P0562 description the battery supplies electricity to the engine control module even when the ignition switch is off this electricity allows the ecm to store data such as diagnostic trouble code dtc history freeze frame data fuel trim values and other data.
A vehicle s charging system works to maintain a normal vehicle voltage level usually in the range of 14 1 to 14 4 volts dc at idle with headlights turned off.
If your system is continuously losing its date and time settings then there is a good chance that something is wrong with its cmos chip or the cmos battery in use.
There could be a pending code.
The pcm can control the charging system by controlling a power or a ground circuit to the voltage regulator inside the alternator.
Normally modern cars use a 12 volt system.
Obd ii code p0562 is defined as a system voltage low.

Sounds like you may have some other issues here.
If the battery voltage falls below a minimum level the ecm will conclude that there is a fault in the power supply circuit.
Try checking for trouble codes even if the check engine light is not on.
If the computer regulates voltage output in the system check there too.
P0562 is stored when the engine control unit detects a low voltage in the electrical system.
The purpose of the charging system is to maintain an ideal vehicle voltage level which is usually 14 1 14 4 volts dc when the vehicle is idling with the lights off.
