The code identifies an implausible condition in the monitored system. The component named in the code is not automatically the defective part.
What does P0562 mean?
System Voltage Low. The engine or vehicle control system detected that a measured value, control response, or communication signal was outside the expected range.
Common symptoms

- multiple apparently unrelated fault codes
- control modules reset or drop offline
Likely causes
- weak or deeply discharged battery
- alternator or regulator undercharging
- ground strap, battery terminal, or cable has excessive resistance
Sensible diagnostic order
- measure resting and charging voltage
- load-test the battery
- check grounds and voltage drop
Can I continue driving?
Stop if warning lights, power loss, or rough running occur. If the check-engine light flashes, the engine shakes strongly, warning messages increase, or power drops significantly, stop and arrange professional assistance.
