Town Car V8-4.6L VIN V Flex Fuel (2006)
The SCP communications network permits inter-module communications between the data link connector (DLC), and the network modules. When the
diagnostic tool communicates to modules on the SCP communications network, the diagnostic tool must request all information or initiate module
commands.
Check the SCP communications network circuits between the networked modules and the 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 in one or both SCP communications network circuits, damage to the module
connector, a problem with a in-line connector, or a problem with the DLC C251.
