vh2q, thanks for the update as I think you're the first one to have actually pulled codes off our i-MiEV. As we had discussed before, in your situation (having rental i-MiEVs on an isolated island), I would try to get a MUT3. I was hoping zzcoopej would further develop EVBatMon to include both error-code reading as well as reset capability.
I take it the car runs ok despite the warning?
