<p>The inventive method and system permits diagnosing the type of fault condition associated with powering an electrical load that has a high side driver portion and a low side driver portion. Selectively powering the driver portions in different combinations and sampling a plurality of associated diagnostic feedback signals associated with each of the driver portions permits diagnosing the type of fault present. In one example, three different powering combinations and three different diagnostic feedback signals are used. This example permits diagnosing one of seven different possible fault conditions.</p> |
