ECM Naming Changes

Certain ECMs connect to the service tool over two data links at the same time. The service tool shows a message popup when the ECM is only detected on one link. The service tool has been changed to add the text **INCOMPLETE** in the ECM name when the connection is incomplete. Service tool features that display a connection icon also use a new icon for an incomplete connection.

Configuring Cat Electronic Technician to use the Communication Adapter 3
For Cat Electronic Technician to work with the Communication Adapter 3, the settings must be changed to select the Communication Adapter 3 as the Communication Interface Device:
Step 1 Start Cat Electronic Technician.
Step 2 Click the Stop Connect button when it appears.
Step 3 Select the Utilities menu.
Step 4 Choose “Preferences > Modify…”.
Step 5 Select the Communications tab.
Step 6 Select Cat Comm Adapter 3 (RP1210) and click OK.
NOTE: Because a growing number of products require multiple data link service, the “Enable Dual Datalink Service” checkbox has been pre-selected.
Servicing ECMs on more than one data link requires this check box to be enabled.
Failure to do this will result in undetected ECMs and reduced functionality.
