Quick answer

For 2012–2013 Mitsubishi i-MiEV vehicles in the U.S., DTC P1D15 is identified by Mitsubishi as “Current Command Abnormal” during onboard-charger operation. The verified TSB instructs clearing the DTC, performing a regular charge, and checking whether it resets. If it resets, replace the onboard charger/DC-DC converter; if it does not, Mitsubishi identifies it as an intermittent malfunction.

1. What does P1D15 mean?

For 2012–2013 Mitsubishi i-MiEV vehicles in the U.S., DTC P1D15 is identified by Mitsubishi as “Current Command Abnormal” during onboard-charger operation. The verified TSB instructs clearing the DTC, performing a regular charge, and checking whether it resets. If it resets, replace the onboard charger/DC-DC converter; if it does not, Mitsubishi identifies it as an intermittent malfunction.

2. Technical explanation

Verified Mitsubishi/NHTSA TSB evidence states that P1D15 is evaluated while the onboard charger is permitted to charge by the EV-ECU. The judgment criteria include an EV-ECU charging-current command greater than 5.5 A under the stated 100 V judgment condition, or greater than 10 A under another stated condition. The supplied evidence is truncated after that point, so the complete second condition is not established by verified evidence.

3. What system is affected?

Onboard charger/DC-DC converter and EV-ECU charging-current command monitoring.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

Not yet established by verified evidence.

6. Possible causes

  • Mitsubishi’s verified TSB diagnostic outcome is a replaceable onboard charger/DC-DC converter if P1D15 is cleared, a regular charge is performed, and the DTC resets.
  • If the DTC does not reset after the specified test, Mitsubishi identifies the result as an intermittent malfunction.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • Use the Mitsubishi diagnostic procedure in TSB-20-54-003: clear the DTC, perform a regular charge, and check whether the DTC resets.
  • Have diagnosis and any onboard charger/DC-DC converter replacement performed by qualified service personnel.

10. Step-by-step troubleshooting

  1. Clear the DTC.
  2. Perform a regular charge.
  3. Check whether P1D15 is set again.
  4. If P1D15 is set again, Mitsubishi instructs replacement of the onboard charger/DC-DC converter, referring to the OBC removal and installation procedure in the TSB.
  5. If P1D15 is not set again, Mitsubishi identifies the condition as an intermittent malfunction and refers to the service manual guidance for coping with intermittent malfunctions.

11. When to contact service

Service is appropriate if P1D15 is present, because the verified Mitsubishi procedure specifies a charge test and, if the DTC resets, onboard charger/DC-DC converter replacement.

12. What the service center may check

  • Confirm P1D15 is present.
  • Clear the DTC.
  • Perform a regular charge.
  • Recheck whether P1D15 resets.
  • Follow Mitsubishi’s intermittent-malfunction guidance if it does not reset.

13. Possible repair or resolution

  • If P1D15 resets after clearing the DTC and performing a regular charge, replace the onboard charger/DC-DC converter according to Mitsubishi TSB-20-54-003.
  • If P1D15 does not reset, Mitsubishi classifies the result as an intermittent malfunction.
