Aviator 2WD V8-4.6L DOHC (2003)
Test J2-J3
Normal Operation
The DEATC module 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 DEATC module C228b 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 DEATC module C228b.
Possible Causes
-
