Abstract

A vehicle includes main contactors powered via a low voltage bus and disposed electrically between a traction battery and a high voltage bus, and a controller. The controller, responsive to the contactors remaining open following activation of the low voltage bus and reported voltage values associated with the high voltage bus being less than a threshold, operates a horn of the vehicle.
