Charger will not start charging; display shows E01 immediately after plugging into vehicle.

Safety first: Disconnect the charger from the wall outlet or turn off the dedicated breaker before inspecting any wiring. Never open the charger while it is energized.

• 1. Inspect the J1772 connector: Look closely at the small pilot pin (usually the thin pin near the center). Check for bending, corrosion, or contamination. Clean gently with a dry, soft brush; do not use liquids.
• 2. Check cable strain: Flex the cable gently near the handle and near the charger housing. If the error appears only when the cable is bent, the pilot conductor may be broken internally.
• 3. Test with another vehicle (if available): If the charger works on another EV, the issue may be with the vehicle inlet rather than the charger.
• 4. Power-cycle the charger: Turn off the breaker for 2 minutes, then restore power and reconnect to the vehicle. If E01 returns immediately, the internal control board may be faulty.
• 5. Do not bypass safety circuits: If the pilot pin or cable is damaged, replace the cable assembly or contact a qualified technician. Operating with a compromised pilot circuit is unsafe.
