Possible Causes
Corrupted firmware on main control PCB, Failed communication between display board and main board, Loose ribbon cable, Power interruption during update
How to Fix / Troubleshooting
Safety first: Turn off power before disconnecting any internal cables.
- Power-cycle the unit: Turn OFF the breaker for 2–3 minutes, then turn ON and check if E10 clears.
- Inspect internal data cables: If your Zencar model has a separate display or Wi-Fi module, open the housing (if user-serviceable) and reseat any ribbon or data cables between boards.
- Attempt firmware recovery: If Zencar provides a user firmware tool, follow their official procedure to reload firmware via USB, Wi-Fi, or app. Do not interrupt power during this process.
- Check for visible board damage: Look for burnt components or corrosion on the main control PCB and display board.
- If E10 persists: The main control PCB firmware may be irrecoverable; replace the main control PCB or entire charger per Zencar guidance.
