OBD-II GPS Vehicle Tracker: Install Guide Intro

This guide focusses on the installation / use of OBD-II trackers. This family of GPS trackers utilizes the vehicle diagnostic port in most domestic vehicles. Most vehicles are compatible with the OBD-II standard, but some are not. Check your vehicle's owner's manual to determine if there is a potential issue.OBD-II vehicle diagnostics port

Note: Since the vehicle manufacturer is responsible for complying with the SAE standard, we cannot guarantee that our GPS OBD-II tracking device will perform with your vehicle.

OBD-II Background

The OBD-II specification is controlled by the Society of Automobile Engineers and defines the method for requesting diagnostic data and provides a list of standard parameters from the engine control unit. The specification was first released in 1979. Today, depending upon the vehicle, the tracker can retrieve values that include: throttle, engine RPM, fuel available. In some vehicles, the device can even retrieve engine diagnostic codes.

Where is my OBD-II Port?

The OBD-II diagnostic port, also known as a Data Link Connector (DLC), is generally located on the driver's side of the car or truck under the dash. The location will vary between different manufacturers, models, and production years of a car or truck model. Consult the vehicle owner's manual for detailed location information.
