Quick answer

For applicable U.S.-market 2012, 2014, and 2016 Mitsubishi i-MiEV vehicles, verified Mitsubishi service-bulletin evidence includes a diagnostic repeat-check for DTC P0A0D. If P0A0D is stored again after the specified erase, restart, drive, and recheck sequence, the procedure directs technicians to return to Step 1; if it is not stored, the diagnosis is complete.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P0A0D mean?

For applicable U.S.-market 2012, 2014, and 2016 Mitsubishi i-MiEV vehicles, verified Mitsubishi service-bulletin evidence includes a diagnostic repeat-check for DTC P0A0D. If P0A0D is stored again after the specified erase, restart, drive, and recheck sequence, the procedure directs technicians to return to Step 1; if it is not stored, the diagnosis is complete.

2. Technical explanation

The supplied official NHTSA manufacturer-communication evidence is from Mitsubishi TSB-19-54-003, TSB-19-54-004, and TSB-19-54-005, published March 13, 2019. The cited material is within a Battery Management Unit (BMU) and main-drive lithium-ion battery diagnostic procedure. It instructs a technician to erase stored DTCs, cycle the electric motor switch from LOCK (OFF) to ON and then START, run the electric motor unit, drive the vehicle, and check whether P0A0D is stored in the EMCU. The documented decision point is: if P0A0D is stored, return to Step 1; if it is not stored, the diagnosis is complete. The supplied evidence does not establish a plain-language definition of P0A0D beyond this procedure text.

3. What system is affected?

Verified evidence places this code in Mitsubishi diagnostic material for the Battery Management Unit (BMU), main-drive lithium-ion battery, and an EMCU DTC recheck.

4. How serious is this code?

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. The service material includes a technician-directed drive-and-recheck step, but that does not establish that every vehicle displaying P0A0D is safe to drive.

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 technician.
  • Do not attempt high-voltage battery or BMU repairs yourself.
  • Provide the technician with the stored code P0A0D and the applicable Mitsubishi TSB references.

10. Step-by-step troubleshooting

  1. Verified technician procedure: erase the stored DTC.
  2. Verified technician procedure: set the electric motor switch from LOCK (OFF) to ON.
  3. Verified technician procedure: set the electric motor switch to START and start the electric motor unit.
  4. Verified technician procedure: run the vehicle and check whether P0A0D is stored in the EMCU.
  5. If P0A0D is stored again, the documented procedure says to return to Step 1.
  6. If P0A0D is not stored, the documented procedure says the diagnosis is complete.

11. When to contact service

Service evaluation is appropriate because the verified procedure is a Mitsubishi technician diagnostic process involving the BMU and main-drive lithium-ion battery. The supplied evidence does not establish urgency or drivability restrictions.

12. What the service center may check

  • Check whether DTC P0A0D is stored in the EMCU after the documented erase, restart, drive, and recheck sequence.
  • The cited service material lists the MB992927 battery air leak check tool kit for an air-leak check of the main-drive lithium-ion battery; however, the supplied excerpt does not establish that an air-leak check is required for every P0A0D case.

13. Possible repair or resolution

  • Verified resolution criterion: after the documented recheck, if P0A0D is not stored, the diagnosis is complete.
  • If P0A0D is stored again, return to Step 1 of the Mitsubishi diagnostic procedure. The supplied evidence does not provide the earlier steps or a specific repair.
