Explorer AWD V6-4.0L VIN K Flex Fuel (2003)
Test H1-H3
Normal Operation
The instrument cluster 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. Check
circuits 914 (TN/OG) and 915 (PK/LB) between the instrument cluster C220b and the data link connector (DLC) C251. Total resistance values must
not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in circuit 914 (TN/OG) or 915 (PK/LB), damage to the DLC C251, or
damage to the instrument cluster C220b.
Possible Causes
-
circuits 914 (TN/OG) or 915 (PK/LB) shorted to ground or open
-
instrument cluster C22Ob
-
DLC C251
