Possible Causes

Damaged main control board microcontroller, Corrupted firmware after surge, Failed low-voltage regulator on control board, Loose internal harness between display board and main control board

How to Fix / Troubleshooting

Safety first: Disconnect the Megear charger from power before opening the housing. Surges can leave components in an unsafe state.

  • 1. Full reset:
    • Unplug the charger or switch off the breaker for at least 5 minutes.
    • Restore power and check if E06 clears.
  • 2. Inspect internal connections:
    • Open the housing with power disconnected.
    • Check the ribbon cable or harness between the display/LED board and the main control board.
    • Reseat connectors firmly; look for bent pins or corrosion.
  • 3. Look for surge damage:
    • Examine the main control board for burn marks, cracked ICs, or bulging components.
    • If any component appears physically damaged, the entire board should be replaced.
  • 4. Surge protection:
    • If E06 occurred after a storm or power event, consider installing a whole-house surge protector or a dedicated surge device for the EV circuit to prevent recurrence.

Because E06 indicates an internal diagnostic failure, board-level repair is typically not practical for homeowners. Replace the main control board or the entire Megear unit if the error persists.
