1. What does P1D00 mean?
For 2012–2013 Mitsubishi i-MiEV vehicles in the US, DTC P1D00 indicates low AC input voltage during permitted onboard charging. The verified fail-safe action is that charging stops.
2. Technical explanation
Verified Mitsubishi/NHTSA TSB evidence groups P1D00 with related AC-input-voltage diagnostics. During a period when the EV-ECU permits onboard charging, P1D00 is judged when the effective AC input voltage is more than 40 V and less than 80 V. The same source identifies P1D01 for AC input voltage above 270 V and P1D02 for AC input voltage above 300 V momentarily.
3. What system is affected?
Onboard charging system / AC input voltage monitoring.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- Charging stops.
6. Possible causes
- Failure of the AC power supply on the supply side.
- Failure of the charging cable.
- Failure of the onboard charger.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
No while the fault condition is active: verified evidence states that charging is stopped.
9. What you can safely do
- Do not attempt high-voltage repairs.
- Have the AC supply, charging cable, and onboard charger assessed by qualified service personnel.
10. Step-by-step troubleshooting
- Confirm the DTC using appropriate diagnostic equipment.
- Qualified service personnel should evaluate the AC power supply at the supply side, the charging cable, and the onboard charger. Detailed diagnostic steps are not established by the supplied verified evidence.
11. When to contact service
Service evaluation is appropriate because the verified fail-safe function stops charging and the listed possible causes include the onboard charger.
12. What the service center may check
- Check the AC power supply on the supply side.
- Check the charging cable.
- Check the onboard charger.
13. Possible repair or resolution
- Not yet established by verified evidence.
