Freestar V6-4.2L VIN 2 (2004)
Test H1-H2
Normal Operation
The speed control actuator communicates with the diagnostic tool through the SCP communications network circuits 914 (TN/OG) and 915 (PK/LB).
If one of the bus wires becomes shorted to ground or voltage, or if some but not all termination resistors are lost, communications can continue at a
degraded level. Check circuits 914 (TN/OG) and 915 (PK/LB) between the speed control actuator C122 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 circuit in the SCP network, damage to the DLC C251, damage
to the speed control actuator C122, or a problem in the in-line connector.
Possible Causes
-
SCP circuits 914 (TN/OG) and 915 (PK/LB), shorted to ground or open
-
DLC C251
-
