During "Add" ECM:

It does not matter if the ECM unit is new (in transport mode) or used (previously "added" or "removed").

• When "Add" ECM is carried out using Tech2, the master key code is copied from CIM to ECM.
• The keys that worked previously will still be functional.

After "Add" ECM:

Figure 9: The illustration shows the same ECM as in  Fig 1 , but with the master key code copied from CIM, illustrated here in green.
