Mitsubishi P0706
23-002 has been applied to the vehicle or the SCU software is already at the new version, it is not necessary to perform this bulletin. AFFECTED VEHICLES Certa in 2022-2023 Outland
Quick answer
For 2012–2017 Mitsubishi i-MiEV vehicles in the US, P0706 is listed as applicable, but the supplied verified evidence does not establish its i-MiEV-specific meaning, symptoms, safety status, or repair procedure. The cited Mitsubishi/NHTSA bulletin describes a different affected vehicle population: certain 2022–2023 Outlander vehicles.
This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P0706 mean?
For 2012–2017 Mitsubishi i-MiEV vehicles in the US, P0706 is listed as applicable, but the supplied verified evidence does not establish its i-MiEV-specific meaning, symptoms, safety status, or repair procedure. The cited Mitsubishi/NHTSA bulletin describes a different affected vehicle population: certain 2022–2023 Outlander vehicles.
2. Technical explanation
The supplied official NHTSA manufacturer communication states that, in a vehicle with older SCU software, replacing and updating the TCM can create a software mismatch between the TCM and SCU. If a temporary inhibitor-switch continuity fault occurs while operating the gear selector, P0780 and P0706 may appear and the vehicle may become undrivable. The bulletin says this situation can still allow the vehicle to be driven before that fault event occurs. This evidence is explicitly associated with certain 2022–2023 Outlander vehicles, not the supplied i-MiEV applicability record.
3. What system is affected?
Transmission control module (TCM), SCU software, and inhibitor switch are identified in the supplied bulletin. An i-MiEV-specific affected system is not yet established by verified evidence.
4. How serious is this code?
Not yet established by verified evidence for the 2012–2017 Mitsubishi i-MiEV. For the Outlander scenario described in the bulletin, the condition can result in an undrivable vehicle.
5. Symptoms you may notice
- For the Outlander scenario in the supplied bulletin, P0780 and P0706 may appear if a temporary inhibitor-switch continuity fault occurs while operating the gear selector.
- For the Outlander scenario, the vehicle may become undrivable.
- i-MiEV-specific symptoms are not yet established by verified evidence.
6. Possible causes
- For the Outlander scenario, an old SCU software version combined with replacement and update of the TCM may create a mismatch between TCM and SCU software.
- For the Outlander scenario, a temporary continuity fault of the inhibitor switch while operating the gear selector is identified as the event associated with P0780/P0706 and an undrivable condition.
- i-MiEV-specific causes are not yet established by verified evidence.
7. Can I still drive the vehicle?
Not yet established by verified evidence for the 2012–2017 Mitsubishi i-MiEV. The cited Outlander bulletin states that the vehicle can still be driven in the described software-mismatch situation, but may become undrivable if the specified temporary inhibitor-switch continuity fault occurs.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
- If P0706 is present on a 2012–2017 Mitsubishi i-MiEV, arrange professional diagnosis using vehicle-specific service information.
- Do not rely on the cited Outlander bulletin as an i-MiEV repair instruction.
- If the vehicle cannot be shifted or driven normally, seek service assistance.
10. Step-by-step troubleshooting
- Confirm the vehicle model, model year, region, and all stored diagnostic codes.
- Have a qualified service provider determine whether any Mitsubishi i-MiEV-specific diagnostic information applies.
- No verified i-MiEV-specific test procedure is supplied.
11. When to contact service
Contact a Mitsubishi dealer or qualified EV service provider for i-MiEV-specific diagnosis. The supplied official bulletin is not verified as applicable to the i-MiEV.
12. What the service center may check
- For the Outlander scenario described in the bulletin, service relevance includes TCM software, SCU software version, and the inhibitor switch continuity condition.
- No verified i-MiEV-specific service checks are supplied.
13. Possible repair or resolution
- For the affected Outlander vehicles described by the bulletin, the bulletin references SCU software version and states that the bulletin is unnecessary if TSB-23-23-002 has already been applied or the SCU software is already at the new version.
- A repair resolution for the 2012–2017 Mitsubishi i-MiEV is not yet established by verified evidence.
