Figure 1.1 – Lockout (DDDL warning)

The lockout tab in the calibration window allows you to protect certain functions in the ECM so that they can only be changed if you have the function lockout password as well as the calibration password.

If the ECM supports function lockout, the lockout tab will show the current lockout settings when the calibration is retrieved from the ECM.

check any functions that you want locked out (prevented from being changed), and uncheck any that you want to be able to change.

enter the calibration password in the password box (4 numbers).

press transmit to send the new lockout settings to the ECM.
