A hybrid vehicle includes an isolation switch disposed between a first bus that is electrically coupled to a starter for an engine and a second bus that is electrically coupled to a power converter and accessory loads. The hybrid vehicle includes a controller programmed to normally command the switch closed, and, in response to expiration of a predetermined time interval without starting the engine, command the switch to open for a predetermined duration to perform diagnostics on the isolation switch.
