Town Car V8-4.6L VIN V Flex Fuel (2006)
Normal Operation
The remote audio/climate control 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 remote audio/climate control module C3160a 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 remote audio/climate control module C3160a.

-
SCP data plus circuit 914 (TN/OG) open
