Charging session does not start; vehicle shows ‘charging error’ and ABL wallbox displays E01 shortly after plugging in.

Safety first: Disconnect the vehicle, switch off the ABL charger at the upstream circuit breaker, and verify that no LEDs are lit before touching the unit.

Step-by-step checks:

• Inspect the Type 2 plug and cable: Look for bent, recessed, or burned pins on the plug and on the vehicle inlet. Clean light oxidation with a dry, non‑metallic brush. Do not use liquids.
• Try a different cable: If your ABL wallbox has a Type 2 socket (not tethered), test with a known‑good cable. If E01 disappears, the original cable is defective.
• Check cable locking: Ensure the plug is fully inserted until the mechanical latch clicks. A partially inserted plug can cause pilot signal errors.
• Power‑cycle the charger: Turn the upstream breaker OFF for 2 minutes, then ON. Wait for the ABL charger to complete its self‑test and then reconnect the vehicle.
• Inspect control pilot wiring (installer level): With power OFF and cover removed, verify that the CP and PP terminals on the ABL main control board are firmly clamped and that the harness to the socket/lead is not damaged.

When to call a technician: If E01 persists with multiple vehicles and cables, the CP/PP circuitry on the ABL main control board is likely defective and the board should be tested and replaced by a qualified technician.
