1. What does P1D02 mean?

For a 2012–2013 Mitsubishi i-MiEV (US), DTC P1D02 indicates that the onboard charger detected AC input voltage above 300 V momentarily while charging was permitted by the EV-ECU. The documented fail-safe action is that charging stops.

2. Technical explanation

NHTSA-hosted Mitsubishi TSB-20-54-003 lists P1D02 under onboard-charger judgment conditions. The criterion is: effective AC input voltage is more than 300 V for a moment. The bulletin states that the charge is stopped as the fail-safe and backup function.

3. What system is affected?

Onboard charger and the external AC charging-power input path.

4. How serious is this code?

The supplied verified evidence does not assign a severity rating. Charging interruption is documented.

5. Symptoms you may notice

  • Charging stops.
  • P1D02 may be stored in the onboard charger when its specified judgment conditions are met.

6. Possible causes

  • Failure of the AC power supply on the supply side.
  • Failure of the charging cable.
  • Failure of the onboard charger.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

The documented fail-safe action is that charging stops. Whether charging can resume or be safely attempted is not yet established by verified evidence.

9. What you can safely do

  • Do not attempt high-voltage repair procedures.
  • Use manufacturer-qualified service diagnosis for the charging system.

10. Step-by-step troubleshooting

  1. The cited Mitsubishi diagnostic procedure begins by rechecking whether the DTC is set in the onboard charger after erasing the DTC. Further procedure details are not established by the supplied evidence.

11. When to contact service

Contact a Mitsubishi-qualified service facility if P1D02 is present or charging stops.

12. What the service center may check

  • Confirm whether P1D02 is stored in the onboard charger.
  • Evaluate the AC power supply on the supply side, charging cable, and onboard charger using the manufacturer diagnostic procedure.

13. Possible repair or resolution

  • Not yet established by verified evidence. The verified bulletin identifies the AC supply, charging cable, and onboard charger as probable-cause areas but does not establish a specific repair from the supplied excerpt.
