Mitsubishi P101C
Return to Step 1. NO : The diagnosis is complete. Code No. P1A15: High Voltage Circuit (1) DANGER When servicing the high voltage system parts, always shut off the high voltage b
Quick answer
For a 2016 Mitsubishi i-MiEV (US), verified evidence identifies P101C in EV-ECU diagnostic step 12: after erasing the DTC, fully charging through the quick-charging connector, and rechecking the EV-ECU, P101C being set again directs the procedure back to step 1. If it is not set again, the diagnosis is complete.

1. What does P101C mean?
For a 2016 Mitsubishi i-MiEV (US), verified evidence identifies P101C in EV-ECU diagnostic step 12: after erasing the DTC, fully charging through the quick-charging connector, and rechecking the EV-ECU, P101C being set again directs the procedure back to step 1. If it is not set again, the diagnosis is complete.
2. Technical explanation
The supplied official Mitsubishi/NHTSA TSB evidence places P101C within an EV-ECU diagnostic procedure for the electric motor unit and main drive lithium-ion battery. The verified step is: erase the stored DTC, connect the quick-charging connector to charge the battery completely, then check whether the DTC is set in the EV-ECU. The documented decision is: P101C set again = return to step 1; P101C not set again = diagnosis complete. The supplied evidence does not establish a plain-language fault definition for P101C, a specific failed part, or a repair.
3. What system is affected?
EV-ECU diagnostic procedure relating to the electric motor unit and main drive lithium-ion battery.
4. How serious is this code?
Unknown. Not yet established by verified evidence.
5. Symptoms you may notice
Not yet established by verified evidence.
6. Possible causes
- 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?
Not yet established by verified evidence. The verified diagnostic procedure uses the quick-charging connector to charge the battery completely before checking whether P101C resets.
9. What you can safely do
- Have diagnosis performed according to the applicable Mitsubishi service procedure.
- For service of high-voltage-system parts, the cited procedure states that high voltage must be shut off by removing the service plug.
- Do not perform high-voltage servicing unless qualified and following Mitsubishi procedures.
10. Step-by-step troubleshooting
- Check the DTC again in the EV-ECU.
- Erase the set DTC.
- Connect the quick-charging connector and charge the battery completely.
- Check whether P101C is set again.
- If P101C is set again, return to step 1 of the Mitsubishi diagnostic procedure.
- If P101C is not set again, the diagnosis is complete.
11. When to contact service
Professional service is appropriate because the verified procedure concerns high-voltage-system components and specifies high-voltage shutdown before servicing those parts.
12. What the service center may check
- Use the EV-ECU to erase and recheck the DTC.
- Perform the documented full charge through the quick-charging connector before the recheck.
- Follow the earlier steps of the Mitsubishi diagnostic procedure if P101C resets.
13. Possible repair or resolution
- Not yet established by verified evidence. The supplied evidence only states that diagnosis is complete if P101C does not reset after the documented erase, full-charge, and EV-ECU recheck.
