1. What does P1D11 mean?

For a 2012–2013 Mitsubishi i‑MiEV sold in the US, DTC P1D11 means the on-board charger detected excessive output current during an authorized charging event. Verified fail-safe action: charging stops.

2. Technical explanation

The verified TSB describes P1D11 as “Output Current (Over).” It is judged while the on-board charger is permitted to charge by the EV-ECU, when the system detects the output-section overcurrent signal a predetermined number of times or more.

3. What system is affected?

On-board charger/DC-DC converter charging system.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Charging is stopped when P1D11 is detected.

6. Possible causes

  • The verified source identifies the on-board charger/DC-DC converter as the component to replace if the DTC returns after the specified confirmation procedure.
  • If the DTC does not reset during the specified confirmation procedure, the verified TSB identifies this as an intermittent malfunction.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Charging is stopped when this DTC is detected. Whether charging can resume or continue safely is not yet established by verified evidence.

9. What you can safely do

  • Arrange diagnosis by a qualified Mitsubishi EV service provider.
  • Do not attempt high-voltage on-board charger or DC-DC converter repair yourself.
  • Record whether the fault returns after a regular charge, if this can be done normally and safely.

10. Step-by-step troubleshooting

  1. Erase the DTC.
  2. Perform a regular charge.
  3. Check whether P1D11 is set again.
  4. If P1D11 is set again, the verified TSB directs replacement of the on-board charger/DC-DC converter.
  5. If P1D11 does not set again, the verified TSB classifies the condition as an intermittent malfunction and refers technicians to Mitsubishi intermittent-malfunction diagnostic guidance.

11. When to contact service

Contact a Mitsubishi dealer or qualified EV service facility, particularly if P1D11 returns after a regular charging attempt.

12. What the service center may check

  • Confirm the DTC using the manufacturer diagnostic process.
  • Erase the DTC and perform a regular charge.
  • Recheck whether P1D11 resets.
  • If it resets, follow the TSB on-board charger/DC-DC converter replacement procedure.
  • If it does not reset, follow Mitsubishi intermittent-malfunction diagnostic guidance.

13. Possible repair or resolution

  • If P1D11 returns after the specified erase-and-recharge check, replace the on-board charger/DC-DC converter according to TSB-20-54-003.
  • If P1D11 does not return during the check, address it as an intermittent malfunction using the referenced Mitsubishi diagnostic process.
