In today’s marketplace, it seems that there are a variety of GPS tracking devices that plug into the On Board Diagnostic (OBD II) port in the vehicle. The consumer might be lead to believe that all of these devices are the same or that they provide the same data. Some telematics devices on the market plug in to the diagnostic port to power the device only. Others provide data about the faults occurring in the vehicles engine.
The Geotab engine diagnostic tools offer the user the broadest selection of protocols supported and the richest dataset available to optimize fleet efficiency and ensure the productive and safe operation of the fleet’s assets.
According to Colin Sutherland, Executive Vice President, Sales & Marketing, Geotab's technology can be referred to as “the Rosetta Stone” of the telematics market. The Geotab device understands and translates a comprehensive set of vehicle diagnostic codes, including those of hybrid and electric vehicles.
The term “OBD compliant” refers not to one standard but rather to a multitude of protocols all of which exist under the OBD umbrella. These protocols are typically identified by alphanumeric code that defines the communications methods that the vehicle uses to communicate. These protocols span a variety of different manufacturers and a manufacturer may alter the protocols from model year to model year.
Vehicles first started being equipped with a diagnostic port in the mid 1990s. Since the first diagnostic ports were installed in vehicles, the protocols and the data they make available have changed greatly. OBD over CAN is the latest variation. CAN refers to the “Controller Area Network” — in an OBD over CAN a central network combines the data from additional inputs in the vehicle to allow Geotab to report non-engine related data using the same OBD connection in the vehicle. An example of non-engine data would include: seat belt use monitoring and passenger detection in light duty vehicles or the automatic detection and reporting on PTO use in Heavy-Duty vehicles.
It is important to consider the variety of vehicles in a fleet when evaluating an OBD solution. While all newer vehicles have a diagnostic plug not all telematics solutions are designed to work with all of the vehicle types that exist today. Some important questions to ask:
Remember to keep in mind the data you wish to consume today, as well the long-term goals for telematics. How can the technology ease the administration of maintenance and total cost of ownership calculations on all of the assets in your fleet?
In addition to installation, access to data, security, and software/firmware updates are some other factors that are critical to success. For advice on comparing telematics systems, read our free white paper The Open Platform Advantage: How to Get Maximum Value from Your Telematics System
