A vehicle includes a magnetic switch and a controller. The magnetic switch is coupled with a trailer connection receptacle housing and aligned with a magnet in a cap of the housing while closed. The controller is configured to, in response to detecting an open position of the cap based on a state of the magnetic switch, periodically supply a voltage pulse less than an operating voltage across contacts of the housing to detect continuity therebetween. The controller is further configured to, in response to detecting a closed position of the cap, inhibit the voltage pulse. The magnetic switch may be a reed switch.
