Mountaineer AWD V6-4.0L VIN K Flex Fuel (2003)
Test A4
Normal Operation
The vehicle security module 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 vehicle security module C3008f 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 vehicle security module C3OO8f, or a problem in the in-line connector
C2095.
