Town Car V8-4.6L VIN V Flex Fuel (2006)
J2-J3
Normal Operation
The navigation module communicates with the diagnostic tool through the standard corporate protocol (SCP) communications network, circuits 914
(TN/OG) and 915 (PK/LB). Check the SCP circuits between the navigation module C4209 and the data link connector (DLC) C251. The total
resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the SCP network, damage to the
DLC C251, or damage to the navigation module C4209.
Possible Causes
-
SCP data plus circuit 914 (TN/OG) open
-
SCP data minus circuit 915 (PK/LB) open
