1. What does P1D10 mean?

For a 2012–2013 US Mitsubishi i-MiEV, DTC P1D10 is documented as an onboard-charger output-current deviation condition. The listed fail-safe action is that charging stops.

2. Technical explanation

Verified Mitsubishi/NHTSA TSB evidence states that, while AC power is being supplied, P1D10 is set when the difference between target output current and actual output current is greater than 1.0 A or less than -1.0 A. The documented fail-safe and backup function is charge stoppage.

3. What system is affected?

Charging system; the verified evidence identifies the EV-ECU and onboard charger as probable-cause areas.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Charging stops.
  • P1D10 may be stored while AC power is being input.

6. Possible causes

  • EV-ECU failure is listed as a probable cause.
  • Onboard charger failure is listed as a probable cause.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

The verified fail-safe action for P1D10 is that charging stops.

9. What you can safely do

  • Do not attempt high-voltage diagnosis or repair.
  • Have the vehicle evaluated with the specified diagnostic procedure by qualified service personnel.

10. Step-by-step troubleshooting

  1. Use scan tool MB991958 to confirm the DTC, as specified in the verified diagnostic evidence.
  2. The documented first diagnostic question is whether DTC P1D15 is also set.
  3. If P1D15 is set, the source directs diagnosis to the P1D15 current-command-abnormal procedure.
  4. If P1D15 is not set, the source directs the technician to proceed to Step 2; the supplied evidence does not include Step 2.

11. When to contact service

Service evaluation is appropriate because the verified procedure requires scan-tool confirmation and identifies EV-ECU and onboard-charger faults as probable causes.

12. What the service center may check

  • Confirm P1D10 using scan tool MB991958.
  • Check whether P1D15 is set.
  • Follow the P1D15 current-command-abnormal procedure if P1D15 is present.
  • Continue with the manufacturer procedure after Step 1; subsequent steps are not included in the supplied evidence.

13. Possible repair or resolution

  • Not yet established by verified evidence. The supplied source identifies probable-cause areas but does not provide a completed repair outcome.

19. Frequently asked questions

What does Mitsubishi i-MiEV code P1D10 mean?

For the applicable vehicle, the verified diagnostic evidence describes P1D10 as a condition where target and actual onboard-charger output current differ by more than 1.0 A or by less than -1.0 A while AC power is being input.

What happens when P1D10 is set?

The documented fail-safe and backup function is that charging stops.

What vehicles are covered by the supplied evidence?

The supplied applicability evidence covers US-market 2012–2013 Mitsubishi i-MiEV vehicles.

What should be checked first for P1D10?

The verified procedure says to use scan tool MB991958 to confirm the DTC, then determine whether P1D15 is also set.
