1. What does P0AE7 mean?
For applicable U.S. Mitsubishi i-MiEV model years 2012, 2014, and 2016, verified Mitsubishi service information includes P0AE7 in a post-repair EV-ECU DTC recheck: if P0AE7 is stored or set again, the procedure directs technicians to return to Step 1; if it is not present, the diagnosis is complete.
2. Technical explanation
The supplied official Mitsubishi communications do not establish a standalone plain-language definition, root cause, symptom set, or repair for P0AE7. They establish that P0AE7 is checked in the EV-ECU after stored DTCs are erased and the electric motor switch is cycled through the specified positions. A recurring P0AE7 directs the diagnostic process back to Step 1. Absence of P0AE7 at that recheck completes the diagnostic procedure.
3. What system is affected?
EV-ECU diagnostic process. A more specific affected component or system is not yet established by verified evidence.
4. How serious is this code?
Unknown. Severity is not yet established by verified evidence.
5. Symptoms you may notice
- No driver-observable symptoms are established by the supplied verified evidence.
- The verified procedure concerns whether P0AE7 is stored or set again in the EV-ECU after a DTC-clear and switch-cycle recheck.
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.
9. What you can safely do
- Arrange diagnosis by a qualified Mitsubishi EV service provider if P0AE7 is present or returns.
- Do not attempt high-voltage system service yourself.
- The official service information states that high-voltage servicing requires the high voltage to be shut off using/removing the service plug and use of protective equipment; these are technician-service precautions.
10. Step-by-step troubleshooting
- Verified technician procedure: erase the stored DTCs, cycle the electric motor switch as specified in the applicable service procedure, then check whether P0AE7 is stored or set again in the EV-ECU.
- If P0AE7 is present again, the official procedure directs the technician to return to Step 1.
- If P0AE7 is not present at the recheck, the official procedure states that diagnosis is complete.
- The content of Step 1 is not provided in the supplied verified evidence.
11. When to contact service
Service is appropriate because the verified procedure involves EV-ECU diagnosis and official high-voltage-service precautions. Seek a qualified Mitsubishi EV service provider; urgency is otherwise not yet established by verified evidence.
12. What the service center may check
- Check the EV-ECU for stored or set P0AE7 after clearing DTCs and completing the applicable electric motor switch cycle.
- If P0AE7 recurs, return to Step 1 of the applicable Mitsubishi diagnostic procedure.
- Follow Mitsubishi high-voltage service precautions when high-voltage parts require service.
13. Possible repair or resolution
- No specific repair or component replacement is established by the supplied verified evidence.
- The verified resolution criterion is that P0AE7 is no longer stored or set during the prescribed EV-ECU recheck, at which point the procedure states the diagnosis is complete.
