Charger displays E10 proximity or latch fault; vehicle does not lock connector or charging will not start.

Safety first: Turn off power at the breaker before inspecting the connector or opening the unit.

• Check connector latch operation: With power OFF, insert the J1772 handle into the vehicle and operate the latch. It should move smoothly and spring back. A sticky or broken latch can prevent the proximity switch from signaling correctly.
• Inspect handle for damage: Look for cracks, impact damage, or signs of water ingress around the latch area. If present, replace the J1772 charge cable assembly.
• Cable continuity test (advanced): With power OFF and cable disconnected internally, measure continuity of the PP conductor from the handle to the control board connector. An open circuit indicates a broken wire; replace the cable.
• Board input check: If the handle and cable test good, the PP sensing circuit on the main control board may be defective and require board replacement.
