ADAPTER AS 3574609 - Caterpillar

Machine ECM 1
The following is a list of Diagnostic Trouble Codes (DTCs) associated with the bluetooth transceiver of the machine.
Table 1
Machine ECM 1 (MID 299)
DTC Code Description System Response
5874-9 Bluetooth Transceiver: Abnormal Update Rate Operator can not authenticate using bluetooth key or phone app. Each CAN data link circuit is an input and output of select electronic control modules. The data link is designed to carry communications between the electronic control modules.Possible Causes for an FMI 9 Diagnostic code are:
CAN harness wiring failure.
Connector failure.
Transceiver failure.Note: A loss of power in the system to an ECM can cause the ECM to activate this diagnostic code combination. Ensure that ECM modules with this diagnostic code are powered up before proceeding with this procedure.The FMI 9 code means that the ECM has lost all communication with another control module.The preceding diagram is a simplified schematic of the data link connections. The schematic is electrically correct. However, not all the possible harness connectors are shown. Refer to the latest revision of the Electrical Schematic to view the entire circuitry of the machine.Diagnostic Trouble Code Procedure
Prior to beginning this procedure, inspect the harness connectors involved in this circuit. Poor connections are often the cause of problems in an electrical circuit. Verify that all connections in the circuit are clean, secure, and in good condition. Check the wiring for pinch points or abrasions. Look for and repair areas where wires are exposed. If a problem with a connection is found, correct the problem. Verify that this diagnostic code is active before performing a troubleshooting procedure.
Identify the active FMI code associated with the components.
Determine which code is present and use the list below to determine which procedure to follow.
FMI 9 Diagnostic code, proceed to Table 2.
