2. Technical explanation
The verified manufacturer communication identifies DTC P0E5F as being stored in the secondary on-board diagnostic control module A (SOBDM). In the documented condition, the SOBDM and high-voltage battery cannot be charged using a 48-amp AC level.
3. What system is affected?
Secondary on-board diagnostic control module A (SOBDM) and the high-voltage battery charging system.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- Exterior charge-status indicator blinking red.
- High-voltage battery cannot be charged using a 48-amp AC level.
- DTC P0E5F stored in the SOBDM.
6. Possible causes
- Not yet established by verified evidence.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Verified evidence states that the high-voltage battery cannot be charged using a 48-amp AC level. Charging capability at other AC levels or by other charging methods is not yet established by verified evidence.
9. What you can safely do
- Do not rely on 48-amp AC charging if the exterior charge-status indicator is blinking red and P0E5F is present.
- Arrange diagnosis by a Ford dealer or qualified EV service provider.
- Do not attempt high-voltage system repair or disassembly.
10. Step-by-step troubleshooting
- Confirm whether the exterior charge-status indicator is blinking red.
- Have the vehicle scanned for P0E5F in the SOBDM.
- Confirm whether the concern occurs while using a 48-amp AC charging level.
- Use official Ford service information for further diagnosis; additional diagnostic steps are not provided in the verified evidence.
11. When to contact service
Contact a Ford dealer or qualified EV service provider for diagnosis, particularly if P0E5F is stored and 48-amp AC charging is unavailable.
12. What the service center may check
- Check for P0E5F stored in the secondary on-board diagnostic control module A (SOBDM).
- Verify the reported exterior charge-status indicator behavior.
- Verify the inability to charge the high-voltage battery using 48-amp AC charging.
- Review Ford SSM 51866 / NHTSA Manufacturer Communication 10241595.
