Password Protection

Some ECUs have security features built in that allow calibrations to be password protected. If an ECU supports security, the Set Password... and Clear Password... menu items are enabled in the ECU menu. A padlock icon appears in the status bar to show the status of the secure ECU. If another computer is used to connect to a password protected ECU, the password must be entered before the calibration can be downloaded or edited. If the password is not known, the calibration must be erased from the ECU to allow access to the ECU.

Set a password

• Connect to the ECU.
• Select Set Password....
• A dialog box appears prompting for a password. The password must be 6 characters long and can contain any alphanumeric character.
• Enter the password and click ‘OK’.

Clear Password

Once connected to a password protected ECU, the password may be cleared. Clearing the password removes the security such that any PC can connect to this ECU.

To clear the password:

• Connect to the ECU. You will be prompted for the current password.
• Select Clear Password....

If the password is not known and you wish have access to the ECU, you can do this by clearing the current calibration. Connect to the ECU, when prompted for the password, select ‘Clear Calibration’. This will clear the calibration in the ECU allowing a new calibration to be uploaded.
