If you didn't change the srs control unit you're wasting your time.Front impact with airbags deployed = SRS control unit , deployed airbag(s) , seat belt tensioners and front impact sensors. ALL need replaced. Pass. seat weight sensor and ODS will need CALIBRATION.
Maybe aftermarket info is different, but Honda does not list a 'manual' mode for the Insight SRS. Might want to find a shop with a compatible scanner to at least retrieve DTCs at this point , and see if all it states is that due to a new control unit or control unit not being 'initialized' it won't communicate. Go from there.
