Aviator AWD V8-4.6L DOHC VIN H (2003)
Test F5-F7
Normal Operation
The DSM communicates with the diagnostic tool through the UART based protocol (UBP) communications network circuit 693 (OG). If circuit 693
(OG) becomes open or shorted to ground, communications to that module will not be possible. Check circuit 693 (OG) between the DSM C341g and
the DLC C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in circuit 693 (OG),
damage to the DLC C251, damage to the DSM C341g, or a problem in the in-line connector C212.
