P115372 — Fast-charge relay will not close
Quick answer
P115372 indicates that the main relay for DC fast charging does not close when it is commanded, so fast charging is not possible. Driving and normal AC charging are usually unaffected.
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.
