U110016 — System voltage too low
Quick answer
U110016 indicates that the body control module saw the 12 V supply drop too low while the car was awake. Electrical systems may reset or the car may be slow to start; the code clears once the supply is healthy again.
What to check first
- Read all stored fault codes with a scan tool and deal with related codes first.
- Check the 12 V battery state of charge and terminals; a weak 12 V supply causes many electronic faults.
- Inspect the fuses that protect this circuit.
Symptoms you may notice
- Low 12 V battery warning or faults
- Random electrical resets
- U110016 stored in the BCM
- Slow or failed start-up
Can I still drive?
Usually drivable — have it checked soon. If in doubt, park the car and ask a technician — a fault that limits power or shuts the high-voltage system down will not clear by itself.
