HICAS Diagnostic

  •

The instructions to put the HICAS in diagnostic mode specify putting the car in neutral, is this just to prevent the wheels from turning, or is it needed for the diagnostic procedure? The reason I ask, is I didn't connect up the neutral switch when I did my manual conversion, I just adjusted the timing accordingly...
