TIMER AS 1071004 - Caterpillar

Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
Occurrences of lost registration data have been reported from the field. In some instances when the PL321 is registered, the registration message will not be processed by EquipmentManager. As a result, all subsequent messages from the Product Link module will remain in a pending state. The messages will be processed once the registration is successfully completed.The issue may occur during the following events:
When a deregistered PL121 module is being upgraded to a PL321 system
When a PL121 is registered as part of a PL321 system, and then the PL121 is registered as a stand-alone PL121
When a PL321 is deregistered, the PL300 is replaced and the PL321 is registered againFrom a user viewpoint, the registration message will seem to have been lost as no communication of registration confirmation is returned from EquipmentManager. The onboard status will continue to display "Confirmation Pending" in Caterpillar Electronic Technician (Cat ET). This failure mode may result in a delay in receiving registration confirmation.Note: A failed registration that occurs because of an invalid dealer code or machine serial number is not due to an unprocessed registration message.Solution
The EquipmentManager system will log the unprocessed registration message. A product support analyst will be notified of the occurrence. During normal business hours of US (Central Time), the product support analyst will trigger a remote registration. The analyst will use the information from the unprocessed registration message. No further actions will need to be taken by the user.
