P0560 System voltage
What P0560 means
The engine control unit monitors its supply voltage and has found it outside the expected range or unstable. Unstable voltage can cause many unrelated warnings and erratic behaviour of electronic systems.
P0560 is a generic SAE J2012 code: it means the same on every make. The exact cause still depends on the car, so read the freeze-frame data before replacing parts.

Parts and labour at an independent workshop in Europe. Main dealers charge more; the cause decides the bill, not the code.
Symptoms
- Several warning lights at once
- Hard starting
- Flickering lights or dashboard
- Check engine light on
Common causes
- Weak or failing battery
- Loose or corroded battery terminals
- Poor engine or body ground strap
- Faulty alternator or voltage regulator
- Blown fuse in the ECU supply
Can I keep driving with P0560?
You can keep driving, but have it checked within one to two weeks. If the battery warning light comes on, the car may soon fail to start.
What to check first
- Clean and tighten the battery terminals
- Test the battery; resting voltage should be about 12.6 volts
- Check charging voltage with the engine running (about 13.5 to 14.8 volts)
- Inspect ground straps and the ECU power fuses
