Ethernet Data Link #2: Special Instruction
Camera is not accepting the configuration request. Camera displays blue screen or incorrect image.
Each Ethernet 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. The data link consists of internal control circuits and the connecting harness wiring. Possible Causes for an FMI 9 Diagnostic code are: The FMI 9 code means that the monitor has lost all communication with a camera for a period of time. • Camera is not connected to the display. • Camera is not powered or has failed.

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. that all connections in the circuit are clean, secure, and in good condition. Check the wiring for pinch points or abrasions. If a wire issue is found with the Ethernet wiring, the wiring must be replaced not repaired. If a problem with a connection is found, correct the problem. the 3901 diagnostic code is active before performing this troubleshooting procedure. Note: If troubleshooting the symptom of a blue screen in place of a camera image then follow the FMI 9 troubleshooting table below. 1. Identify the active FMI code associated with the Datalink fault. 2. Use the list below to determine which procedure to follow. • FMI 9 Diagnostic code, proceed to Table 2. • FMI 14 Diagnostic code, proceed to Table 3.
