Charger displays E13; LEDs may indicate a communication error; smart features may be unavailable.

Safety first: Network issues do not usually affect electrical safety, but always follow electrical safety when opening the unit.

• Check physical connections: For Ethernet-connected Nissan chargers, ensure the RJ45 cable is fully seated at both the EVSE and router/switch. Replace damaged cables.
• Wi‑Fi signal: For Wi‑Fi models, verify the charger is within range of the access point. Consider relocating the router or adding a Wi‑Fi extender.
• Router settings: Ensure the router allows outbound connections on required ports (consult Nissan documentation). Disable overly strict firewall rules temporarily for testing.
• Reboot network and EVSE: Power-cycle the router, then turn the EVSE breaker OFF for 1 minute and back ON. Check if E13 clears.

If E13 persists and local charging still works, the communication module or firmware may need service or update from Nissan support.
