Hi,
We are starting to have some success using a
ScanGauge II to replicate function of the Graham Miniscanner:
03' Classic Prius and scanguageII - Page 8 - PriusChat Forums
w2co - started the thread and helped diagnose the ABS spike problem. We now can fabricate adapters so the
ScanGauge won't induce problems.
vincent1449p - has PID data for most of the NHW11 including some that may be the elusive 'subcodes' needed to fault-isolate the generic P3125 inverter error.
I got my ScanGauge II last week and am just starting the journey. Too soon to say but my initial testing looks promising.
