P106100 — on-board charger output voltage too low
Quick answer
P106100 indicates that the vehicle control unit detected the on-board charger's output voltage staying too low. The warning lamp lights, the high-voltage system is shut down and cannot be re-energised, so the car cannot be driven.
What to check first
- Read all stored fault codes with a scan tool and deal with related codes first.
- High-voltage system: do not open or disconnect high-voltage components. Refer the car to a technician qualified for high-voltage work.
- Check the 12 V battery state of charge and terminals; a weak 12 V supply causes many electronic faults.
Can I still drive?
Do not drive. 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.
