Hey

 

Nothing to be worried about. The trouble code p0562 is exactly what it says (Low system voltage)

 

It actually means that the Engine control unit has found a voltage below 10 volts for at least 60 seconds when the engine is running on the electric system.

 

There are 3 causes of this problem.

 

1. Either a bad battery which needs to be replaces

2. Alternator is sending a low charge

3. Simple, poor wiring which needs to be changed.

 

You check one by one to see what the issue is. I'd ask you to try and check this issue with another battery first and take it from there
