See Power, Ground and Bus Activity at the OBD2 Port<\/h3>\n

Plugs in between the vehicle’s 16-pin OBD2 port and a scan tool. LEDs confirm power, ground and protocol activity, and every pin is broken out to a banana jack for a multimeter or oscilloscope.<\/p>\n

    Key Features<\/h4>\n
      \n
    1. \n
      Power and Ground LEDs<\/h5>\n

      Red lights when pin 16 has battery power; green lights when pins 4 and 5 are grounded.<\/p>\n<\/li>\n

    2. \n
      Protocol Activity LEDs<\/h5>\n

      Yellow LEDs on pins 2, 6, 7, 10, 14 and 15 show which lines are active while a scan tool talks to the vehicle.<\/p>\n<\/li>\n

    3. \n
      All 16 Pins Broken Out<\/h5>\n

      The jack layout matches the OBD2 connector, so each pin can be probed while the scan tool stays connected.<\/p>\n<\/li>\n

    4. \n
      Meter and Scope Ready<\/h5>\n

      Standard 4 mm banana sockets take plain or sheathed safety plugs.<\/p>\n<\/li>\n

    5. \n
      Flexible Lead<\/h5>\n

      The extension cable has an elastic TPU jacket.<\/p>\n<\/li>\n<\/ol>\n<\/section>\n

        Caution<\/span><\/h5>\n
          \n
        • Do not connect any load drawing more than 1 A through the box.<\/li>\n
        • Never short pins 16, 4 and 5 together, and do not jumper the jacks unless you know the circuit; misuse can damage the vehicle’s data network.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/section>\n<\/div>","protected":false},"excerpt":{"rendered":"
