ScanGauge keeps saying connecting

First – be sure the key is in the RUN position, and/or start engine.

If that does not solve the problem, then the ECU may not responding properly. You may need to manually set, or “Force”, the operating MODE of your ScanGauge. Please refer to the user manual for your ScanGauge for information on how to access the MODE setting screen. See the digital copy of user manual (reset ScanGauge or Read/ Set Operating mode page 56-57) here

Next – confirm your vehicle meets the minimum OBDII, OBD2 or EOBD compatibility requirements. In Australia 16 pin trapezoid shape (OBD2 style) plug does not make your vehicle OBD2 compatible. It is your ECU that dictates whether your vehicle is OBD1 or OBD2. Click the following link to check whether your car is OBD2 compatible


Some gauges are blank 

Some sensors are not used in the vehicle or data is not reported by ECU. Only about 10% of vehicles show FPR and 50% show MAP.

ScanGauge does not turn on after the battery went flat

Disconnect and reconnect the unit from all ends and try again. 99.9% of such a cases get resolved like this. 


ScanGauge does not show boost 

ScanGauge2 and ScanGauge3 is designed to read boost (BST) as part of its build in digital gaues via OBD2. This is avaialble on most turbo and super charged engines. The build in boost gauge BST uses the MAP sensor to calculate the boost. Negative value is normal. When a negative value is reported it is reporting the vacuum. 

If boost is not showing but MAP does you need to switch in between MAP or BST in the settings of your unit. See user manual page 17 here

*due to updates done on Isuzu models 2017+ BT is not reporting as OBD2 standard so ScanGauge2 is not able to display it. Read more here
