Enhanced Diagnostics Help
OBD Fusion has support for enhanced diagnostics for Ford, Lincoln, Mercury, Mazda, Lexus, Toyota, Scion, Nissan, Infiniti, Mitsubishi, Dodge, RAM, Chrysler, Jeep, and some FIAT and Alfa Romeo vehicles. Enhanced diagnostics provides access to many additional
modules and parameters that are not available over standard OBD2. Some common examples include being able to read and clear ABS codes and reading transmission temperature. This page describes
how to determine whether enhanced diagnostics are available for your vehicle, how to purchase enhanced diagnostics, and how to access the enhanced diagnostic features.
Determining whether enhanced diagnostics are available
Before purchasing enhanced diagnostics for your vehicle, you should check whether your specific vehicle is supported by the enhanced diagnostic packages by following these steps.
- Connect to your vehicle by following the instructions on the Settings > Help > Connection page.
- Open the vehicle editor on the Settings > Vehicle Editor page.
-
Use the Select buttons to enter the full year, make, model, and option for your vehicle. You must use the Select buttons to enter this information.
If your year, make, model, or option is not listed, you can manually enter it, but enhanced diagnostics will not be available for your vehicle.
-
After you have fully set the vehicle year, make, model, and option using the Select buttons, the Get Enhanced OEM Add-Ons button will be visible if enhanced diagnostics are supported by your vehicle.

Purchasing enhanced diagnostics
Before purchasing enhanced diagnostics for your vehicle, you should check whether your specific vehicle is supported by following the steps in the previous section.
- Open the Settings > Purchase Extras page and wait for the app to load the list of extra items.
- Select the category corresponding to the make of your vehicle.
-
You will see a list of packages for each model year and a package that includes a range of model years. Packages for individual model years support
vehicles that match the listed model year. For example, Toyota 2018 Enhanced Diagnostics supports 2018 model year vehicles. The package that includes a range of
model years supports vehicles in the model year range. For example, Toyota 1996 - 2020 Enhanced Diagnostics supports model years 1996 to 2020. As new model years are
added, they will be included in the package that supports multiple model years, and an update to that package will be available without the need to repurchase the package.
-
Find and select the package corresponding to your vehicle year, such as Ford 2013 Enhanced Diagnostics. If you would like to purchase the add-on for multiple model years,
select that add-on from the list. If you have vehicle(s) supported by this add-on, you will see a list of the vehicles at the bottom of the page. If you do not have any
vehicles supported by this add-on, you will see a message indicating that you do not have any vehicles supported by this add-on.

- Press the blue price button in the top-right corner to purchase the enhanced add-on.
Using enhanced diagnostics
Once you have purchased and downloaded an enhanced diagnostic package for your vehicle, you are ready to connect to your vehicle and access the enhanced information. Follow the steps below to connect to your vehicle and access enhanced diagnostic information.
Enhanced diagnostics are meant for diagnostic purposes only. You should not connect to your vehicle or initiate diagnostic functions while the vehicle is in motion.
- Open Settings > Vehicle Editor and select the vehicle that you want to connect to by pressing Menu > Select Vehicle.
- On the OBD Fusion main page, press the Connect button.
-
You will be prompted to select an enhanced diagnostic network. Select the network that contains the module that you want to diagnose and press the Connect button.
If you are not prompted for an enhanced network, make sure you fully selected the year, make, model, and option of your vehicle in the vehicle editor using the Select buttons.

- When you first connect to an enhanced network, OBD Fusion will scan your vehicle for supported enhanced PIDs. Please be patient and let the scan complete. The supported enhanced PIDs will be saved so that you do not have to scan this enhanced network the next time you connect.
- Once the scan completes, you are ready to configure enhanced PIDs and read enhanced trouble codes, as explained in the following sections.
Configuring enhanced PIDs
-
You configure enhanced PIDs in a similar way to configuring standard SAE PIDs. When configuring a PID for a dashboard gauge, graph, PID value, etc., look for the category corresponding to the make of your vehicle, and select the category.

-
You will see a list of enhanced modules for your vehicle, and you can select the module to see the list of PIDs supported by that module. Note that if you are connected when configuring PIDs, you will only see the connected network.
You can configure PIDs when not connected, in which case you will see all available networks for the active vehicle.

-
After you select the module, select a PID from the list. You can use the search box at the top of the screen to search for a specific PID.
Reading enhanced trouble codes
When connected to an enhanced network, open the Diagnostics > Trouble Codes page. If this is the first time you opened this page since opening the app, OBD Fusion will automatically read trouble codes. Otherwise, press Menu > Refresh to read codes.
You will be prompted to select the modules from which to read codes. Once you have selected the modules to read, press the Continue button.
Clearing enhanced trouble codes
You should only clear codes with the ignition ON and the engine OFF. You should never try to clear codes with the engine running.
When connected to an enhanced network, open the Diagnostics > Trouble Codes page, then press Menu > Clear Trouble Codes. You will be prompted to select the modules on which to clear codes. Once you have selected the modules to clear, press the Continue button.
After clearing codes, OBD Fusion will automatically read codes, and you will be prompted again to select the modules to read as described in the Reading enhanced trouble codes section.
If you upgrade or move to a different phone and you previously purchased enhanced diagnostic add-ons, you will need to restore purchases on your new phone.
Open the Settings > Purchase Extras page and press the Restore button. After purchases are restored, you will need to download the add-on content.
Purchases will only be restored for the app store account that you used to purchase the add-ons.
