ScanGauge For Heavy Diesel Vehicles

ScanGauge for heavy diesel vehicles is a great way to keep an eye on all important systems on your rig. From temperature and engine gauges to fuel, mileage, cost and trip data and everything in between!

The ultra compact PLUG & PLAY ScanGauge vehicle monitor features include:

  • Built-in and programmable digital gauges
  • Multiple trip computers
  • Fuel saving features
  • Engine diagnostic scan tool
  • Performance monitor
  • & more

Unlike smaller passenger petrol and diesel vehicles, OBDII is not the standard for large diesel powered vehicles and trucks – these type of vehicles rely on the J1939 and J1708 protocols. Vehicle diagnostic tools for these vehicles are both cumbersome and expensive.

The ScanGauge-D and ScanGauge-KR will change all that!

Both ScanGauge-D and ScanGauge-KR work with most 1990 and newer large diesel vehicles that use J1939 (9-pin) or J1708 (6-pin) OBD protocols. This includes Freightliner, International, Kenworth, Mack, Benz, Navistar, Volvo, Cummins, Caterpillar and many more.

ScanGauge-KR is more suitable for professional drivers who make income by the hour or by the KMs to help achieve the maximum amount of profit while driving. It includes a set of additional real-time digital gauges dedicated to showing you your actual profit or loss as it relates to your fuel usage and driving style.

Works with J1939 & J1708 Vehicles

The ScanGauge-D and ScanGauge-KR work with most 1990 and newer large diesel over-the-road vehicles. They are equipped with a unique dual connector cable designed to accommodate both the J1939 protocol with a 9-pin diagnostic port as well as the J1708 protocol with 6-pin diagnostic port.




ScanGauge-D and ScanGauge-KR provide real-time gauges to show you what is going on “under the hood” with more than 15 built-in digital gauges. The gauge screen allows you to select and display 4 gauges at a time, so you can monitor the current operating conditions of your vehicle in real-time.

Improve Your Fuel Economy With Scangauge

ScanGauge-D and ScanGauge-KR provide real-time data about your vehicle’s instant and average fuel economy, fuel used, cost of fuel used for each trip, cost per KM, Litres per hour and more!

There are many ways to reduce your fuel usage and increase fuel economy. Real time feedback like what the ScanGauge provides is one of the most effective.

With five built-in trip computers, the ScanGauge can keep track of everything from fuel cost to distance traveled and everything in between. Data is stored on the ScanGauge and is retained even when the power is disconnected. Each trip computer starts automatically and information is available anytime during the trip.


Time & Distance Trip Computer Fuel & Tank Trip Computer
ScanGauge includes three trip computers based on time and distance. They include the Current Trip, Today Trip and Previous Day Trip. Each trip computer starts automatically and tracks the following parameters: The ScanGauge includes two trip computers based on the current tank of fuel. They include the Current Tank and Tank to Empty. Each trip computer starts automatically when you tell ScanGauge you have filled your tank.

The ScanGauge can check for Engine Diagnostic Trouble Codes (DTCs) and if found, can display how many there are and the Trouble Codes themselves. Using the internet or repair manuals, these can be translated to the failed component and repairs can be made.

  • Reads Trouble Codes
  • Clears Trouble Codes
  • Shows Conditions When Trouble Was Detected (RPM, COOLANT, TEMP etc)
  • Turns Off “CHECK ENGINE” Light
  • Shows When Onboard Tests Have Been Completed And Vehicle Is Ready To Pass OBDII emissions Testing
