Scanning a file for fault codes

The Scan function reads the file currently open in Source and lists all the fault codes it already contains, so you can see and pick what to act on without typing codes by hand.

Scan is not available for every ECU. When the loaded ECU supports it, a magnifying-glass icon appears next to the fault-code entry field (Figure 1).

Reading the results

When you click Scan, the program analyses the loaded file, searches it for every fault present and shows them in a table (Figure 2). Each code has a checkbox:

Ticked — the code is active in the ECU; it will show up if the vehicle is diagnosed.
Unticked — the code is disabled and will not be detected by the ECU.

Untick the codes you want to eliminate, then press “Clear (Unflagged)” to remove several codes in one operation.

Note — Re-activating faults is not supported: Scan only clears (disables) codes, it cannot turn a fault back on.

Saving the window position

You can move the table anywhere on screen; click the highlighted icon (Figure 3) to memorise that position so the table always opens in the same place.

The other icon (Figure 4) clears the memorised position and returns the table to its default location (as on first launch).

Exporting the scan

The Export button (Figure 5) saves the table of fault codes you are currently viewing.

Figure 5

Export opens a dialog (Figure 6) where you choose the destination folder, type a file name and click SAVE to store the list as a text file. Exported scans can be opened and compared later in Tools.
