SEAL 5342193 - Caterpillar

This section contains steps that can be used to help determine the possible cause of erratic reports of interval. Check for active diagnostic codes for the Product Link. Correct any diagnostic codes before proceeding. The following items should be visually inspected for damage: PL121SR radio, PL300 module, antenna, and cables. Verify that there are no loose connections.The Product Link system depends on several communication links 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 satellite network for VHF communications is operational in the geographic area of concern. The network is operational when messages can travel to the satellite and the messages can travel to the earth and Caterpillar.
The Product Link system is correctly configured to communicate on the network for VHF communications. This was verified during manufacturing tests.
The worldwide network of Caterpillar's computers is passing messages to the software for the Caterpillar Equipment Manager (EM).
EM is configured properly and the software is functioning.The Product Link module nor the radio should not be replaced without verifying that these issues have been investigated. Contact the Caterpillar Technical Communicator for aid in resolving these issues.Refer to the Product Link device configuration and status information in Systems Operation, Troubleshooting, Testing and Adjusting, RENR7911, "Diagnostic Capabilities" to ensure that the lack of reporting is not due to the power mode. The unit is likely to have been configured correctly if the following statements exist:
There is no position report after moving the machine ("Position Report Minimum Location Change").
The SMH report is received.There is likely to be a problem with the systems GPS. Proceed with the following steps to determine the cause:Test Step 1. ACCESS THE PRODUCT LINK THROUGH CAT® ELECTRONIC TECHNICIAN (CAT ET).
Connect the Cat ET service tool to the machine.
Verify that the ECM (Product Link) is available.Expected Result:The ECM (Product Link) is available.Results:
OK - The ECM (Product Link) is available. Proceed to Test Step 3.
NOT OK - The ECM (Product Link) is not present in the Cat ET screen.Repair: Verify that the wiring for the Product Link has been installed correctly. Check the wiring with a multimeter. If the ECM ( Product Link) is not available, refer to Systems Operation, Troubleshooting, Testing and Adjusting, "Electronic Service Tool Does Not Communicate with ECM".STOPTest Step 2. VERIFY IF THE MACHINE HAS MOVEDVerify if the machine has moved more than the configured minimum distance ("Position Report Minimum Location Change") since the last known Position Report.Expected Result:The machine has not moved.Results:
OK - The machine has moved less than the configured minimum distance ("Position Report Minimum Location Change") since the last known position report. Therefore, the machine has not sent any position reports.STOP
NOT OK - The machine has moved more than the "Position Report Minimum Location Change" or machine movement is unknown. Proceed to Test Step 3.Test Step 3. VERIFY THAT THE PRODUCT LINK MODULE IS IN POWER MODE 1.
Select "Status Parameters" for Cat ET.
Verify that the "Power Mode Status"
