ScanGauge-D Heavy Diesel Truck Monitor & Diagnostic Scan Tool – J1939/J1708

Live Engine Gauges & Heavy Diesel Diagnostics

The ScanGauge-D Heavy Diesel Truck Monitor provides real-time engine monitoring, fault code diagnostics and fuel economy tracking for compatible heavy diesel vehicles. Supporting J1939 and J1708 protocols, it features over 15 digital gauges, four simultaneous readings, programmable X-Gauge™ functions, five trip computers and a performance monitor. Designed for trucks, buses and heavy machinery, its compact, plug-and-play design delivers essential vehicle data through a backlit LCD display.

Main Features

• J1939 & J1708 Heavy Diesel Compatibility – Supports compatible heavy diesel trucks, buses, agricultural machinery and earthmoving equipment equipped with J1939 9-pin or J1708 6-pin diagnostic connections.
• 15+ Real-Time Digital Engine Gauges – Monitors essential engine parameters, including coolant temperature, oil pressure, engine RPM, turbo boost, battery voltage, engine load and fuel consumption, depending on vehicle ECU support.
• Four Simultaneous Gauge Displays – Displays up to four selected engine parameters simultaneously, providing convenient access to critical operating information through a customisable digital interface.
• X-Gauge™ Programmable Monitoring – Expands monitoring capabilities with vehicle-specific parameters such as exhaust gas temperature, DPF soot load, transmission temperature, fuel rail pressure and other supported ECU readings.
• Heavy Diesel Fault Code Diagnostics – Reads and clears supported diagnostic trouble codes, helping operators identify engine faults, review available diagnostic information and assist with troubleshooting.
• Five Integrated Trip Computers – Includes three time-and-distance computers and two fuel tank computers for tracking travel distance, operating hours, fuel consumption, average speed, estimated range and trip costs.
• Real-Time Fuel Economy Monitoring – Provides instantaneous and average fuel consumption readings in L/100 km, litres per hour and kilometres per litre, alongside fuel cost calculations for improved operating cost awareness.
• Integrated Performance Monitor™ – Measures acceleration and braking performance, allowing operators to save, recall and compare recorded performance runs over time.
• Customisable Backlit LCD Display – Features an adjustable-colour LCD screen with five-button operation for clear viewing and convenient navigation of engine gauges, trip information and diagnostic functions.
• Plug-and-Play Diagnostic Connection – Connects directly to the vehicle's compatible diagnostic port using the supplied J1939 9-pin cable or J1708 6-pin adapter, without requiring permanent wiring or additional power connections.
• Metric & Imperial Measurement Options – Supports selectable measurement units, including kilometres, litres, degrees Celsius and kPa, providing flexibility for Australian heavy vehicle applications.
• Retained Trip Computer Data – Stores recorded trip information within the device, allowing operators to access previously collected travel and fuel consumption data even after the power supply is disconnected.
• Compact Dashboard Mounting Design – Features a space-saving housing measuring approximately 121.9 × 38 × 25.5 mm, with supplied Velcro mounting tape for convenient installation inside the vehicle cabin.
• Australian Firmware & Local Support – Supplied with Australian firmware pre-installed, local Australian technical support and a three-year Australian warranty for added ownership confidence.
