Mountaineer 2WD V8-4.6L SOHC VIN W (2003)
Test I2-I3
Normal Operation
Under normal operation the EATC 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 EATC 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 EATC module C228b.
Possible Causes
-
circuits 914 (TN/OG) or 915 (PK/LB) shorted to ground or open
