3472-9 5591-9 ARD Air Pressure Control System : Abnormal Update Rate The ECM has lost all communications with the ARD combustion air controller over the Cat Data Link.
The code is logged.
The check engine lamp is illuminated. Note: If a 1639-2 diagnostic code is active, verify that the following information is correct before proceeding with this procedure:
The part number of the flash software for the Machine ECM
The part number of the flash software for the Machine Security System ECM
The part number of the Machine ECM
The part number of the Machine Security System ECMIf the Caterpillar Electronic Technician (ET) will not communicate with the ECM, refer to Troubleshooting, "Electronic Service Tool Does Not Communicate" before you begin this procedure. The procedure verifies that electrical power is being supplied to the ECM and to the service tool connector.The data links are used to communicate information between the engine ECM and other control modules that are a part of the application. Cat ET also communicates with the ECM via the data links.The service tool connector contains connections for electrical power and for the data links.When the keyswitch is in the OFF position, Cat ET may communicate with the ECM. However, the communications may be disrupted and the communications may require frequent reconnection. In order to avoid this problem, place the keyswitch in the ON position when Cat ET is being used.Cat ET may display the following error message:"The version of the ECM is not recognized and the integrity of the changed parameters and displayed data is not guaranteed."This message indicates that one of the following conditions exist:
The flash file in the ECM is newer than the version of Cat ET.
The latest version of Cat ET has not been installed.
