1. What does P1D07 mean?

For a 2012–2013 US Mitsubishi i-MiEV, DTC P1D07 indicates an on-board charger output-voltage over condition detected while charging was permitted by the EV-ECU. Verified TSB evidence states that charging is stopped as the fail-safe response.

2. Technical explanation

The verified diagnostic description for P1D07 is “Output Voltage (Over).” The judgment condition is while the on-board charger is allowed to charge by the EV-ECU. The criterion is detection of an overvoltage signal at the rectification area for a predetermined number of times or more.

3. What system is affected?

On-board charger/DC-DC converter charging system; the verified evidence specifically references the on-board charger and EV-ECU charging authorization.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Charging is stopped.

6. Possible causes

  • The verified TSB directs replacement of the on-board charger/DC-DC converter if the DTC returns after the specified erase-and-regular-charge check.
  • Any further underlying cause is not yet established by verified evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

The verified fail-safe response is that charging is stopped. Whether charging can resume or proceed under other conditions is not yet established by verified evidence.

9. What you can safely do

  • Arrange diagnosis by a qualified Mitsubishi EV service facility.
  • Do not attempt high-voltage charger or DC-DC converter repair yourself.
  • Record whether P1D07 returns after charging, for the service technician.

10. Step-by-step troubleshooting

  1. The verified TSB procedure is to erase the DTC.
  2. Perform a regular charge.
  3. Check whether the DTC is set again.
  4. If P1D07 is set again, the TSB directs replacement of the on-board charger/DC-DC converter.
  5. If P1D07 is not set again, the TSB identifies this as an intermittent malfunction and refers to the service manual’s intermittent-malfunction guidance.

11. When to contact service

Contact a Mitsubishi EV-qualified service facility, particularly if P1D07 returns after the erase-and-regular-charge check.

12. What the service center may check

  • Erase DTC P1D07.
  • Perform a regular charge.
  • Confirm whether P1D07 resets.
  • If it resets, replace the on-board charger/DC-DC converter according to TSB-20-54-003 and its referenced removal-and-installation procedure.
  • If it does not reset, evaluate as an intermittent malfunction using the referenced service information.

13. Possible repair or resolution

  • If the DTC returns after the specified test, replace the on-board charger/DC-DC converter.
  • If the DTC does not return, the verified TSB classifies the condition as intermittent; a permanent repair is not established by the supplied evidence.
