Operation Description:There are problems that could be reported with the Product Link System but the problems are not caused by the Product Link Module. The following section describes the problems. The section contains steps that are used to determine the possible cause. Check for active diagnostic codes for the Product Link. Correct any diagnostic codes before proceeding. The module, the antenna, and cables should be visually inspected for damage. Verify that there are no loose connections.Description of the Problem:
The intervals between reports are erratic. The Product Link system depends on several communication links in order to transfer data from the machine to the office. The following procedures assume that these communication links are operating properly. The proper Communication links are listed below:

The Product Link module is correctly configured to communicate on the Orbcomm network. This was verified during manufacturing tests.
The worldwide network of Caterpillar's computers is passing messages to the software ("CPLS-Web: Caterpillar Product Link System - PC Software").
The CPLS is configured properly and the software is functioning.The Product Link module should not be replaced without verifying that these issues have been investigated.
