ACTUATOR AS-GOVERNOR 2475207 - Caterpillar

System 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 position reports are not received in the office. 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 Orbcomm satellite network 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 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. Contact the Service System Support Center for aid in resolving these issues.Every 24 hours, in "power mode 1", four position reports and one SMU/Fuel report are transmitted. Fewer messages are sent in power mode 2 and power mode 3. If there is no position report after moving the machine and the SMU report is received, the unit is likely to be configured correctly. There is likely to be a problem with the system's GPS. Proceed with the following steps in order to determine the cause:Test Step 1. CHECK THE LED INDICATORS.Check the LED indicators on the Product Link. Expected Result:The red LED is OFF.Results:
RED LED OFF - The red LED is OFF. There are no diagnostic codes. Proceed to Test Step 2.
RED LED BLINKING - The red LED is blinking. There is a diagnostic code.Repair: First correct the diagnostic code. See Troubleshooting, "Diagnostic Code List" for more information. Stop.
RED LED ALWAYS ON - The red LED is always ON. The Product Link has failed.Repair: Replace the Product Link. Stop.Test Step 2. ACCESS THE PRODUCT LINK THROUGH THE ELECTRONIC TECHNICIAN.
Connect the Electronic Technician 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 Electronic Technician screen. Repair: Verify that the wiring for the Product Link has been installed correctly. See Systems Operation, "System Installation". Near the end of the installation procedure, Step 13 checks the wiring with a multimeter. If the ECM (Product Link) is not available, see Troubleshooting, "Electronic Service Tool Does Not Communicate with ECM". Stop.Test Step 3.
