1. An implantable hearing prosthesis, comprising:
- a first implantable component;
a second implantable component electrically connected to the first implantable component;
a physical electrical connection between the first and second implantable components, wherein the electrical connection is configured for electrical signal transfer between the first and second implantable components; and
diagnostic and adaptive circuitry having a plurality of arrangements, wherein each arrangement of the diagnostic and adaptive circuitry enables the performance of one of a plurality of diagnostic tests that each evaluate a different attribute of the electrical connection between the first and second implantable components, and wherein the diagnostic and adaptive circuitry is configured to, based on the results of one or more of the diagnostic tests, perform one or more adaptive functions to change operation of the electrical signal transfer between the first and second implantable component via the electrical connection.

15. A method performed in an implantable hearing prosthesis comprising a switching circuit and first and second physically separate implantable components connected by a lead assembly, the method comprising:
-
actuating the switching circuit to a stimulation operational mode arrangement in which the switching circuit enables power to be supplied from the first implantable component to the second implantable components; switching the switching circuit from the stimulation operational mode arrangement to a diagnostic operational mode arrangement in which the switching circuit enables the performance of one or more diagnostic tests to evaluate an electrical connection between the first and second implantable components; while the switching circuit is in the at least one diagnostic operational mode arrangement, performing the one or more diagnostic tests to evaluate an electrical connection between the first and second implantable components provided by the lead assembly; and based on the results of the one or more diagnostic tests, performing one or more adaptive functions to adjust operation of the electrical connection between the first and second implantable components. - View Dependent Claims (16, 17, 18, 19)

20. An implantable hearing prosthesis, comprising:
-
first and second physically separate implantable components; a cable electrically connecting the first and second implantable components to enable current flow between the first and second implantable components; and circuitry in the first implantable component, wherein the circuitry includes a switching circuit having a plurality of different arrangements each enabling performance of a specific one of a plurality of diagnostic tests each configured to evaluate different electrical attributes of the cable and to adapt current flow through the cable based on the evaluation of the electrical attributes. - View Dependent Claims (21, 22, 23)
