There is a design fault on the IHM08M1 (at least on the 3 units I have) where the switch-mode converter does not start when Vbus is greater than about 12V. The output from this switch-mode drives the output driver enable signal, so there is not FET drive when Vbus is more than 12V, hence the test never works. This may not be the cause of your problem, but it is a good place to start.
