    If you have a 2012 Toyota Highlander with code B1794 Open in Occupant Detection ECU Battery Positive Line, check and see if the windshield has been replaced. There may be a water leak on the passenger side that is getting into the wiring harness at the passenger side feet kick panel. Disconnect a few connectors and check for green fuzzy wires or corrosion.
