How to Fix / Troubleshooting
Safety first: Pilot circuits are low voltage but adjacent to mains.
- Step 1 – Test with another EV: If another vehicle charges normally, the issue may be vehicle‑specific.
- Step 2 – Power cycle both: Reboot the charger (breaker OFF/ON) and power cycle the vehicle (lock/unlock or as per vehicle manual) before retrying.
- Step 3 – Inspect pilot wiring (power OFF): Check the pilot conductor connections at the control board and cable termination for looseness or corrosion.
- Step 4 – Firmware update: Ensure the charger firmware is current via the Electrify America app.
- Step 5 – Replace control board or cable: If pilot measurements (technician) show out‑of‑spec values, replace the control board or cable assembly as indicated.
