1. What does P1D41 mean?

For 2012–2013 Mitsubishi i-MiEV vehicles in the US, verified TSB evidence identifies P1D41 as “Inverter Output Current.” The documented fail-safe action is that charging stops.

2. Technical explanation

NHTSA-posted Mitsubishi TSB-20-54-003, page 43 of 95, lists DTC P1D41 as “Inverter Output Current.” The supplied source excerpt associates this entry with charging being stopped as the fail-safe/back-up function. The evidence excerpt does not establish a complete operating description beyond that documented charge-stop action.

3. What system is affected?

The verified evidence identifies the DTC wording as “Inverter Output Current.” The source also references the EV-ECU, coolant, water pump, radiator fan, and a temperature sensor installed in the on-board charger as diagnostic considerations.

4. How serious is this code?

Unknown. Severity is not established by the supplied verified evidence.

5. Symptoms you may notice

  • Charging stops.

6. Possible causes

  • EV-ECU failure.
  • Insufficient coolant.
  • Water-pump failure.
  • Radiator-fan failure.
  • Failure of the temperature sensor installed in the on-board charger.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

No while the documented fail-safe action is active: the TSB states that charging is stopped.

9. What you can safely do

  • Do not attempt high-voltage component repair.
  • Arrange diagnosis using the manufacturer procedure referenced in TSB-20-54-003.

10. Step-by-step troubleshooting

  1. The supplied evidence states that diagnosis begins with use of a scan tool, but it does not provide the complete diagnostic steps.
  2. Further specific troubleshooting steps are not yet established by the supplied verified evidence.

11. When to contact service

Service need is not explicitly classified in the supplied data. Because charging is documented to stop and the TSB lists multiple component-level possible causes, seek diagnosis by a qualified Mitsubishi EV service provider.

12. What the service center may check

  • Use a scan tool, as indicated by the supplied TSB excerpt.
  • Check the complete Mitsubishi TSB-20-54-003 diagnostic procedure for P1D41. Specific subsequent checks are not included in the supplied evidence.

13. Possible repair or resolution

  • Not yet established by verified evidence. The supplied excerpt lists possible causes but does not document a completed repair resolution.
