TURBOCHARGER 4430326 - 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 PL522 or 523. Correct any diagnostic codes before proceeding. Visually inspect the following items for damage: PL522 or 523 module, antenna and cables. Verify that there are no loose connections.The PL522 or 523 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 network for cellular communications is operational in the geographic area of concern. The network is operational when messages can travel to the satellite and the messages can be sent VisionLink.
The PL522 or 523 system is correctly configured to communicate on the network for cellular communications. Correct configuration was verified during manufacturing tests.
VisionLink is configured properly and the software is functioning.The PL522 or 523 module 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 PL522 or 523 device configuration and status information in Systems Operation, Troubleshooting, Testing and Adjusting, RENR8143, "Diagnostic Capabilities" in order 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 SMH report is received.There is a probability that the system GPS has failed. Proceed with the following steps in order to determine the cause.Test Step 1. ACCESS THE PL522 or 523 THROUGH CATERPILLAR ELECTRONIC TECHNICIAN (CAT ET ).
Connect the Cat ET service tool to the machine.
Verify that the ECM (VIMS Main Module) is present. Expected Result:The ECM (VIMS Main Module) is present.Results:
OK - The ECM (VIMS Main Module) is present. Proceed to Test Step 3.
NOT OK - The ECM (VIMS Main Module) is not present in the Cat ET screen.Repair: Verify that the wiring for the PL522 or 523 has been installed correctly. Check the wiring with a multimeter. If the ECM ( VIMS Main Module) is not present, 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 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 since the last known position report. Therefore, the machine has not sent any position reports.STOP
NOT OK - The 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" is "Power Mode 1". Verify that the "Key Switch Status" is "On". Expected Result:The machine is in "Power Mode 1" and "Key Switch On".Results:
OK - The screens for Cat ET display "Power Mode 1". Proceed to Test Step 4.
NOT OK - Cat ET screens
