There are problems that could be reported with the PL522 or 523 system but the problems are not caused by the PL522 or 523 system. The problem is that the diagnostic information or events are not received at the office. This section contains steps that are used to determine the possible cause. 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 and 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 be sent to VisionLink.
The PL522 or 523 system is correctly configured to communicate on the network for cellular communications.
The worldwide network of Caterpillars computers is passing messages to software of the Caterpillar VisionLink.
The Caterpillar Electronic Technician (Cat ET ) is configured properly and the software is functioning.The PL522 or 523 modules should not be replaced without verifying that these issues have been investigated. Contact your Caterpillar Technical Communicator for aid in resolving these issues.The PL522 or 523 can be configured in order to transmit diagnostics and events to the office. These transmissions are highly dependent on the configuration of the PL522 or 523. The following troubleshooting steps assume that the position and the standard report are being received. Test Step 1. ACCESS THE PL522 AND 523 THROUGH THE CAT ET SERVICE TOOL.
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 2.
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 available, see Systems Operation, Troubleshooting, Testing and Adjusting, "Electronic Service Tool Does Not Communicate with ECM".STOPTest Step 2. CHECK FOR LOGGED EVENTS OR DIAGNOSTICS THAT MAY HAVE OCCURRED.Use the Cat ET service tool to verify the existence of logged events or diagnostics on other ECM systems. Note any events and diagnostics that are not reported.Expected Result:There are no logged events or diagnostics that should have been reported.Results:
OK - There are no logged events or diagnostics that should have been reported. The PL522 or 523 appears to be working correctly.STOP
NOT OK - There are logged events or diagnostics that should have been reported. Monitor the operation of the PL522 or 523 for reporting of events and diagnostics. Problems in this area are not usually a problem with the device. The device should not be replaced.STOP
