See Power, Ground and Bus Activity at the OBD2 Port
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.
- 8–30V DC
- 90 cm Extension Cable

Hauptmerkmale
-
Power and Ground LEDs
Red lights when pin 16 has battery power; green lights when pins 4 and 5 are grounded.
-
Protocol Activity LEDs
Yellow LEDs on pins 2, 6, 7, 10, 14 and 15 show which lines are active while a scan tool talks to the vehicle.
-
All 16 Pins Broken Out
The jack layout matches the OBD2 connector, so each pin can be probed while the scan tool stays connected.
-
Meter and Scope Ready
Standard 4 mm banana sockets take plain or sheathed safety plugs.
-
Flexible Lead
The extension cable has an elastic TPU jacket.
