Town Car V8-4.6L VIN V Flex Fuel (2006)
H2-H3
Normal Operation
The climate control assembly 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 climate control assembly C228b 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 climate control assembly C228b.
Possible Causes
-
SCP data plus circuit 914 (TN/OG) open
-
SCP data minus circuit 915 (PK/LB) open
