On-Board Diagnostics, or OBD, is a computer-based system built into modern passenger cars that monitors emission related controls and performance of the engine, and detects malfunctions. OBD-II systems provide access to the health information of a vehicle and access to numerous parameters and sensors from the Engine Control Unit (ECU). The OBD2 system offers valuable information, including diagnostic trouble codes, when troubleshooting problems.
Diagnostic Trouble Codes and Freeze Frame. Diagnostics Trouble Codes (DTCs) are codes that the vehicle's electronic control unit (ECU) generates when it detects malfunction or other issues. There are three different types of these codes: Confirmed Codes indicate confirmed malfunctioning components. These may require vehicle service to fix.
OBD diagnostic software communicates with the car and reads the diagnostic information from the car. For the communication, a small OBD adapter is needed in addition. The adapter is attached to a car's OBD2 port. It acts as a bridge between your computer/mobile and the car. Using the adapter, OBD software can communicate with the car and present the diagnostic information in user friendly way. It is the software that brings the real value for you. That's why we created OBD Auto Doctor.
To start communicating with your car, you need to have ELM327-based adapter and a OBDII compliant car. Just connect the OBDII adapter to the physical 16-pin OBD connector plug located near the dashboard (typically below the streering wheel), launch the software, and you are ready to go. The connection between the interface and the software can use bluetooth, WiFi, serial port or USB connection depending on the type of hardware you have.
OBD Fusion (formerly TouchScan) is an app that allows you to read OBD2 vehicle data directly from your Android phone or tablet. You can clear your check engine light, read diagnostic trouble codes, estimate fuel economy and much more! OBD Fusion has a ton of features that are used by professional car mechanics, do-it-yourselfers, and users who want to monitor car data during day to day driving. Some of the features include customizable dashboards, real-time graphing of vehicle sensors, emission readiness status, data logging and exporting, oxygen sensor tests, Boost readout, and a full diagnostic report.
Is your check engine light on? Do you want to monitor fuel economy and usage in your vehicle? Do you want cool looking gauges on your Android phone or tablet? If so, then OBD Fusion is the app for you!
OBD Fusion is a vehicle diagnostics tool that connects to OBD-II and EOBD vehicles. Not sure if your vehicle is OBD-2, EOBD or JOBD compliant? See this page for more information: https://www.obdsoftware.net/support/knowledge-base/how-do-i-know-whether-my-vehicle-is-obd-ii-compliant/. OBD Fusion works with some JOBD compliant vehicles and in some cases requires modifications to the connection settings in the app. Please contact us for more information.
You must have a compatible scan tool to use this software. For recommended scan tools, see our website https://www.obdsoftware.net/software/obdfusion. Please note that cheap ELM clone adapters can be unreliable. OBD Fusion can connect to any ELM 327 compatible adapter, but the cheap clone adapters tend to have slow refresh rates and might disconnect randomly.
