Quick answer

P1D06 is a Mitsubishi charging-system DTC for on-board charger output voltage being high. The verified judgment criterion is output (terminal) voltage above 400 V while charging is permitted by the EV-ECU. The verified fail-safe action is that charging stops.

1. What does P1D06 mean?

P1D06 is a Mitsubishi charging-system DTC for on-board charger output voltage being high. The verified judgment criterion is output (terminal) voltage above 400 V while charging is permitted by the EV-ECU. The verified fail-safe action is that charging stops.

2. Technical explanation

The official Mitsubishi/NHTSA TSB evidence defines P1D06 as “Output Voltage (High).” It is evaluated while the on-board charger is allowed to charge by the EV-ECU. The code sets when the charger output (terminal) voltage is more than 400 V.

3. What system is affected?

On-board charger and EV-ECU charging control.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Charging stops.

6. Possible causes

  • EV-ECU failure.
  • On-board charger failure.
  • The TSB also directs review of the user’s AC power-supply usage conditions; if no problem is found, it states the fault is determined to be intermittent.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

No while the P1D06 fail-safe condition is active: verified evidence states that charging is stopped.

9. What you can safely do

  • Do not attempt high-voltage diagnosis or repair.
  • Have the vehicle evaluated by qualified Mitsubishi EV service personnel.
  • Record the charging conditions and AC power-supply usage conditions associated with the event, as the TSB identifies review of those conditions.

10. Step-by-step troubleshooting

  1. Confirm whether the DTC occurred while the on-board charger was permitted to charge by the EV-ECU.
  2. Review AC power-supply usage conditions, as directed by the TSB.
  3. If there are no problems with AC power-supply usage conditions, the TSB identifies the fault as an intermittent malfunction.
  4. Further diagnosis should follow the applicable Mitsubishi service procedure.

11. When to contact service

Service evaluation is appropriate because the verified probable causes include the EV-ECU and on-board charger. High-voltage-system work should be performed by qualified personnel.

12. What the service center may check

  • Check AC power-supply usage conditions.
  • Diagnose the EV-ECU.
  • Diagnose the on-board charger/DC-DC converter in accordance with the applicable TSB procedure.

13. Possible repair or resolution

  • Not yet established by verified evidence. The supplied TSB identifies EV-ECU failure and on-board charger failure as probable causes but does not establish a specific repair outcome in the provided evidence.

19. Frequently asked questions

What does Mitsubishi code P1D06 mean?

It means “Output Voltage (High)” for the on-board charger charging condition.

What sets P1D06?

The supplied official evidence states that it sets when output (terminal) voltage is more than 400 V while the on-board charger is allowed to charge by the EV-ECU.

What happens when P1D06 occurs?

The verified fail-safe function stops charging.

Which vehicles are covered by the supplied applicability evidence?

Mitsubishi i-MiEV, model years 2012–2013, US region.
