P2E39: Battery Charger B Fuse
Standardized SAE J2012 code · P2Exx codes
What does P2E39 mean?
Battery charger B reports a fuse condition. HV charging operation may be impaired. The on-board charger negotiates voltage, current and safety with the EVSE; a fault interrupts charging or limits it to AC slow-charge despite a DC fast charger being attached.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Symptoms
- Charge status indicator shows fault
- Charging may not start or interrupts
- Slower-than-expected charge rate
Common causes
- High Charger main fuse blown
- Medium Internal short circuit
