FORScan Lite for iPhone: User interface manual


 General notes

General notes

Current version of the application is designed for iPhone, it means it works on iPad too but only in the emulation mode. Version of iPad is scheduled to be released later. Version for iPhone currently works with WiFi adapters only.

All screenshots below are provided for Portrait mode, but Landscape mode is supported as well.

The following FORScan Lite application behaviors have to be taken into consideration:

  • If the application is connected to the vehicle, the iOS device will not switch to the sleep (idle) mode - display will be always bright etc. It means high energy consumption. However, the mobile device can be switched to the idle mode by pressing standard Off button on the top of it. When the application is disconnected from the adapter, the device returns back to normal mode of work.
  • When FORScan communicates with the vehicle, standard network activity indicator in the status bar is on
  • FORScan tries to manage connection to the adapter seamlessly. It means, when user switches to an another application, FORScan closes connection to the adapter, and when user switches back, it restores the connection. It means that during the time between the disconnect and connect FORScan doesn't communicate with the adapter. Although in majority of cases it works perfectly, in some cases WiFi adapter may get lost (for example, switch to power saving mode if the idle time was too long).

Buttons connect/disconnect are self-explaining. Sections are the same as in regular Windows version, except that there are no Tests and Service sections (this is main different of Lite version from regular one). Detailed description of every section will be provided later.

At the bottom middle of the main screen we see a progress bar, implemented as a gauge. It is designed to display the current connection progress. In addition to the progress scale, it has 2 status indicators: interface (adapter) (left) and vehicle (right). Initial state of the progress bar is illustrated below:

As you may see, all indicators are gray. When connect button is pressed, FORScan Lite tries to establish a connection to an adapter, then to the vehicle. If connection is successful, the indicator becomes green. Otherwise, it becomes red. For example, if FORScan Lite was able to connect to an adapter, but not able to connect to vehicle, the interface indicator will be green and vehicle indicator will be red.

At the top right corner of the main screen you can see (i)nformation button. Pressing this button switches to the About page:

Most important information on this page is version of the kernel that is displayed right after the version of FORScan Lite for iPhone. All versions of FORScan use the same kernel, so this version number is in sync with the one displayed on FORScan Web site everywhere (announcements, Change history etc).

Note that all screens contain a toolbar at the top, almost all screens also have another one at the bottom. Upper toolbar mainly used for navigation, the lower one is used to call functions.

One more button is missed on the main page: Settings. Actually it is available through standard Settings application on the iPhone, this is a standard way for all iOS applications. Here it is:

Vehicle screen keeps Adapter, vehicle and modules information:

The lower toolbar has 2 buttons: Save at the left and Settings at right. The Save button calls Save menu that allows to save the content of the section:

Note this Save menu structure is typical for FORScan lite, these menus in other sections have the same organization:

Save button - save content to txt file in application document folder. It can be later extracted from there using standard synchronization procedure in iTunes.

Send by email button - this function can be used to send the content as a text file attachment via iOS email client. Unfortunately, when WiFi adapter is used, Internet is usually not available. However, the message can be stored as a draft and sent later, when Internet connection is restored.

The Settings button is used to call settings menu. This version of FORScan has all settings moved to the standard iOS Settings application, so this menu is used for functions that cannot be moved:

Clear cache button - clears all vehicle caches. When FORScan Lite is connected to the vehicle first time, it does full scan of vehicle configuration and saves it to the cache. It may take quite significant time, but subsequent connections are established much faster. If the cache is cleared, FORScan has to perform the full scan again. Besides, the cache may contain some info entered by user, such as Min/Max limits for PIDs. This is why the button is marked in orange. In the meantime, PIDs profiles are not a part of cache, so they are not removed when this function is called.

Send debug info - this button is used to send internal FORScan debug info. This function should be used only if requested by FORScan Support Team. Important note: by default the debug info is not collected. In order to collect it, the Debug setting in the Settings section must be set.

Remove debug info - this button clears all collected internal FORScan debug info.

The log screen keeps log information. The lower toolbar has 2 standard buttons: Save log information and Clear log information:

Note: In contrast to Windows version, where the log grows from the top to the bottom (most recent record is always at the bottom), in iPhone version the log grows from the bottom to the top (most recent record is always at the top).

This screen contains list of DTCs grouped by modules. Every group row displays Module name and 2 buttons at the right: Read DTC and Reset DTC.

The lower toolbar contains the following buttons (from left to right):

  • Read DTC - re-reads DTCs in ALL modules
  • Reset DTC - performs DTC reset in ALL modules
  • Save - calls standard FORScan Save menu
  • Clear - clears the list (but doesn't remove DTCs in modules memory)
Note that the Read/Reset DTCs buttons are applied to ALL modules. In the meantime the Read/Reset DTCs in every module are applied to this module only.

Every DTC in group is displayed in a short view - DTC code and brief description. In order to get more details about the error, you have to tap over the row. The following DTC Detail screen will be opened:

Note that some parts of the text are marked in blue (as hyperlinks). These are "hints". In order to get a hint, you should tap over the hyperlink (in example below, IAT keyword is tapped):

Dashboard, Table and Graph sections of FORScan Lite are organized in the same way. As any other screen, it consists of 3 parts: upper toolbar, work area and lower toolbar:

The work area contains gauges, every gauge displays data for a PID. A gauge has a scale and displays PID value in numeric and analog format, also it shows current measurement unit and PID name. Some PIDs cannot be represent in numeric format, so such PIDs have no scale, just PID name and text value.

Important feature is that you can change size of gauges. You should use standard zoom/pinch gestures. There are 3 sizes supported: small, normal and big:

Another feature is that you can select more PIDs that the Dashboard screen can display. You can then scroll up and down to see hidden PIDs.

If you tap over a gauge, the PID details screen will appear:

This screen contains information about PID. Hints work in the Detailed description in the same way as in the DTC detail screen. Besides, you can change unit type on this screen and also specify Min and Max values for the PID. The Min and Max values are used to calculate the PID scale.

The lower toolbar contains 5 functional buttons, from left to right:

  • Start - starts live streaming
  • Stop - stops live streaming
  • Save - Save menu that allows to save or send by email either FSL (log file in FORScan internal format) or CSV log
  • Open - opens FSL files previously saved to documents.
  • Playpane - this button calls a playpane (not available when live streaming is started) that allows to navigate through the log:

The playpane contains:

  • Time box at the middle that shows total length of the record and current position, in seconds
  • Navigation slider for fast but rough navigation
  • Navigation buttons for slow but precise navigation
The upper toolbar contains the Settings button. When you press on this button, the screen PID profile settings is opened:

The screen allows to change current module. Every module has its own set of PIDs. So when the module is changed, FORScan Lite loads a list of selected profile owned by the module.

Also, the screen allows to manage list of PIDs - add, remove, edit and sort PIDs. To remove a PID, you should click at the remove button at the left of the row. To edit a PID, you should tap on the row - and the PID Detail screen (described earlier) will be displayed. The list can be sorted using standard control in the right side of every row. You should make long tap over the control, then move the selected row to another position. PIDs can be added using Add button from the lower toolbar (described in more details below).

The lower toolbar has the following buttons:

  • Add - adds new PIDs from the list of all available PIDs (described below)
  • Clear All - removes all selected PIDs from the list
  • Save - this button allows to save the currently selected PIDs as a PIDs profile.
  • Load - the button allows to load previously saved profiles.
It should be counted that profiles from different modules are not compatible. So it is not possible, for example, load profile for PCM module if GEM module is selected.

The add new PID screen looks as the following:

The work are of the screen represents all PIDs available for this module. You can select one or several PIDs but setting checkbox at the left side of every selected row. Tap over the row opens the PID Details screen described earlier. The screen has a search bar at the top, you can filter the list using the bar. For example, if you type RPM in the search bar, only PIDs that contain RPM in their name or description will be displayed.

When the live streaming is started, both of the upper and lower toolbars are hidden, to provide more space for the gauges:

You should tap over the screen to show the bottom bar that contains stop button. If your press the stop button, the streaming will be stopped and both bars will return back. If you don't press the stop button and tap over the screen again instead, the lower bar will be hidden again.

The table screen displays PIDs in a table format:

Other functionality of this section is identical to the one described in the Dashboard section.

Back to contents


The graph screen is designed to display PIDs in a graphical format that is most convenient for analysis:

Every graph also displays the current value of PID in numeric format at the top right corner, in the same color. It must be counted that the current value always means the most right visible point of the graph.

Other functionality of this section is identical to the one described in the Dashboard section.
