1st picture shows Claptrap's location (progress on the main story missions until he becomes available). To access this area you must activate the Claptocurrency mission given by Claptrap on Dahl Abandon.
Just above the previous symbol, find a drawing on the wall and jump to the ledge to your left, follow the path to find the symbol. On the area at the north where you find Mordecai's post, behind a collapsed container, right at the entrance of this area. On the small town west of the map, find a ledge on the map's wall, the symbol is at the end of this ledge. In a corner of the huge ramp at the south. Note: the exact location of each symbol on the map pictures is indicated by the in-game mark symbol (not the crosshair cursor). All Vault Symbols locations in all regions in Borderlands 2: Commander Lilith & the Fight for Sanctuary DLC.
