Possible Causes

Failed PWM driver on main control board, Shorted pilot line to ground or line, Damaged pilot resistor network

How to Fix / Troubleshooting

Safety first: Turn OFF the breaker before opening the unit or handling the cable.

  • 1. Inspect pilot pin and cable: Examine the pilot pin in the J1772 connector for damage or contamination. Check the cable for visible damage that could short the pilot conductor.
  • 2. Internal pilot wiring: With power OFF, trace the pilot conductor from the cable gland to the main control board. Ensure the connector is fully seated and that no wires are pinched or abraded.
  • 3. Test with another EV: Confirm that the issue is not vehicle-specific by testing with a different EV if possible.

Resolution: If wiring and connector are intact, the PWM pilot generation circuitry on the main control board is likely defective. Replace the main control board through Lectron service.
