A vehicle includes a traction battery, an auxiliary battery, a voltage converter selectively coupled with the traction battery and coupled with the auxiliary battery, an indicator, and a controller. The controller may be programmed to activate the indicator to indicate presence of a voltage on a high-voltage bus indicative of a current from the traction battery to the auxiliary battery during an ignition-off period in response to detecting an auxiliary voltage on a low-voltage bus less than a minimum voltage and a voltage on the high-voltage bus greater than a predetermined threshold.
