P111892 — Cell temperature too high
Quick answer
P111892 indicates that the battery management system has detected the hottest cell in the pack running too hot, typically after repeated fast charging or when the cooling circuit is not working. The car limits charging and power until temperatures fall.
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.
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.
