P11241A — insulation monitoring level 1 (DC charging)
Quick answer
P11241A indicates that the battery management system detected an insulation fault during DC charging. Power is limited so the car can still be driven at reduced performance.
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?
Have it inspected before further driving. 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.
