The passwords only affect changing parameters from the EMCP 3 control. Changing parameters with Cat ET Service Tool does not require passwords.
The level of password protection that is required for each set point is identified on the parameter set point entry screen. A security level identification number "1", "2", or "3" next to a padlock symbol is displayed on the parameter set point entry screen. Level 3 security is used for the most secure set points and level 1 security is used for the least secure set points.
If the EMCP 3 is currently at the required level of security when viewing a parameter, then the padlock will not appear.
If a parameter is displayed with a padlock, but there is no security level identification number associated with the parameter, then the parameter cannot be changed from the EMCP 3 display.
Level 1 and level 2 passwords are disabled when shipped from the factory. If desired, level 1 and level 2 passwords can be user-defined.
