Save Fleet Calibration (DDEC Only)

Detroit Diesel Diagnostic Link (DDDL) allows saving a password with an individual calibration. This is beneficial for fleets requiring the same calibration across multiple trucks, enabling technicians to transmit calibrations without repeatedly entering passwords.

Fleet managers can use DDDL offline to set calibrations with passwords, restricting access while allowing technicians to apply calibrations without viewing or modifying the saved passwords.

To Save a Calibration with a Password:

Enter the password in the Password box at the bottom of the Calibration window (Save Fleet Cal will be grayed until a password is entered).

Select Save Fleet Cal from the File menu.

In the Save Calibration Datafile As dialog box:

Choose a folder. -> Enter a filename. -> Click Save.
