OBD-II Scan Tools

Making your OBD-II plug work for you

What is an OBD-II connector and does my car have one?

  • Please note: an OBD-II scanner is NOT required for the TripLog solution.

On-board diagnostics (OBD) is an automotive term referring to a vehicle’s self-diagnostic and reporting capability. OBD systems give a vehicle’s owner or a repair technician access to the status of that vehicle’s various subsystems. An example of a subsystem is the check engine light notification.

  • Please note that TripLog requires your vehicle to support a very specific code: OBD PID 31 “Distance traveled since codes cleared”. Vehicles that are OBD-II compliant may or may not support this code and it is hard to predict which vehicles will support this code simply based on their makes and models. Please consult your vehicle’s owner’s manual and other information available online to see if your vehicle supports this code.

What is a Bluetooth OBD-II scanner and where can I buy one?

A Bluetooth OBD-II scan tool is a small device that plugs into your vehicle’s OBD connector and transfers data via Bluetooth. It works with iPhones, iPads, and iPods. Note: we unfortunately do not support OBD-II devices from CellAssist.

 Why do other cheaper WiFi OBD-II scan tools not work?

WiFi OBD-II scan tools have one big caveat. Since they serve as WiFi hotspots/routers but they do not actually connect to the Internet, you cannot use maps, navigation, email and other apps that require Wifi while you are driving.

TripLog strongly recommend Bluetooth OBD-II scan tools for this reason.   LELink Bluetooth Low Energy OBD-II is one of the best products on the market.  It’s been tested and it works flawlessly with TripLog.

Many TripLog users have also been satisfied with the Veepeak OBDCheck BLE OBD-II Scanner as well.
