Concerns programming Body Control Module (BCM) within PATHFINDER

When attempting to complete the 'Replace ECU' Body Control Module (BCM) application within PATHFINDER, the user may notice that PATHFINDER does not respond even though the 'Replace ECU' button has been selected.

Important Note:

To prevent the BCM from being corrupted, DO NOT select any other button within PATHFINDER after the replace button has been selected.
If the BCM is already corrupt, complete the instructions within the 'Action' section of this communication.
