Made in USA. 3 Yrs Limited Warranty on ScanGauge Monitors
For standard OBD-II compatible cars, SUVs, and 4WDs, you have three options:
For heavy diesel trucks and buses using J1939 or J1708 protocols, see the ScanGauge-D or ScanGauge-KR.
Both are designed for heavy diesel vehicles using J1939 (9-pin) and J1708 (6-pin) diagnostic protocols. The ScanGauge-KR includes everything in the ScanGauge-D plus dedicated gauges that display real-time profit or loss based on fuel usage and driving style — making it ideal for professional drivers paid by the kilometre or hour.
ScanGauge 2 and ScanGauge 3 work with any OBD-II compatible vehicle. In Australia, OBD-II compliance is different from other parts of the world — most Australian vehicles became OBD-II compliant between 2006 and 2010.
Important: having a 16-pin trapezoidal port under your dash does not automatically mean your vehicle is OBD-II compatible. It is your vehicle's ECU that determines compatibility — not the shape of the port.
Check the Australian OBD-II compatibility list here. If your vehicle isn't listed, contact us and we'll confirm for you.
The ScanGauge-D and ScanGauge-KR are compatible with most heavy diesel vehicles from 1990 onwards that use J1939 (9-pin) or J1708 (6-pin) diagnostic protocols. This includes trucks, buses, agricultural machinery, and mining equipment from brands including:
Yes. Every ScanGauge includes the unit, a connection cable, mounting hardware, and a user manual — everything required for a tool-free installation. The ScanGauge 3 includes a suction cup window mount as standard. For the ScanGauge II, a window mount is available as an optional accessory.
For cars and light vehicles, plug the ScanGauge into the OBD-II port located under the dashboard, usually near the steering column. It is a 16-pin trapezoidal connector.
For heavy diesel trucks, the ScanGauge-D and ScanGauge-KR include a dual connector cable that fits both the J1939 9-pin and J1708 6-pin round diagnostic ports.
ScanGauge 2 and ScanGauge 3 include over 15 built-in OBD-II gauges as standard — covering engine coolant temperature, RPM, fuel economy, battery voltage, vehicle speed, and more. Additional vehicle-specific gauges such as transmission temperature, EGT, DPF soot levels, and oil temperature can be added using the X-Gauge feature.
Yes. Transmission temperature, EGT, and other vehicle-specific parameters are available via the X-Gauge feature. These are specific to your vehicle's make, model, and year.
For ScanGauge II, refer to page 39 of the ScanGauge II user manual for step-by-step instructions. You can also follow the step-by-step video guide on YouTube.
For ScanGauge 3, use the auto-detect X-Gauge feature in the menu — it will automatically scan and list the available X-Gauges for your specific vehicle.
Yes — all units purchased from ScanGauge Australia and our authorised resellers come with the latest Australian firmware pre-installed. The ScanGauge 3 can be updated via Wi-Fi whenever new firmware is available. No further firmware updates are planned for the ScanGauge II.
All ScanGauge products are made in the USA and backed by a 3-year limited warranty.

Try these steps in order:
No — this is completely normal. Some sensors are not fitted to certain vehicles, or the data simply isn't reported by the ECU. For example, only around 10% of vehicles report fuel pressure (FPR) and around 50% report MAP sensor data. A blank gauge means that parameter is not available on your specific vehicle.
ScanGauge reads boost (BST) as a built-in gauge via OBD-II, available on most turbocharged and supercharged engines. It uses the MAP sensor to calculate boost pressure.
A negative value is normal — it means the engine is reporting vacuum rather than positive boost. If MAP is showing but BST is blank, you need to toggle between MAP and BST in your unit's settings. Refer to page 17 of the ScanGauge II user manual.
Work through these steps:
This is usually caused by an error in the fill-up adjustment setup. Check the values you entered during initial configuration and recalibrate your ScanGauge following the instructions in your user manual.
Disconnect the ScanGauge cable from both the unit and the OBD-II port, then firmly reconnect both ends. This resolves the issue in the vast majority of cases.
