Charger shows E16; vehicle reports charging error and stops

Safety first: Turn OFF power before inspecting wiring or cable.

• Check charger settings: Using the EVgo app or installer interface, verify that the maximum current setting matches the circuit breaker size and charger rating.
• Reset configuration: Restore factory defaults for charging parameters, then re‑enter correct values.
• Inspect cable: Look for physical damage to the EVgo cable that could affect the pilot conductor.
• Test with another vehicle: If E16 only occurs with one EV, its onboard charger may not accept the advertised current.

If E16 persists across vehicles with correct settings, the pilot PWM circuit on the control board or the cable assembly may need replacement by an EVgo‑authorized technician.
