Aviator 2WD V8-4.6L DOHC (2003)
Test K4-K5
Normal Operation
The ABS/TC module or stability assist 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 ABS/TC module or stability assist module C155 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 in circuit 914 (TN/OG) or
915 (PK/LB), damage to the DLC C251, damage to the ABS/TC module or stability assist module C155, or a problem in the in-line connector C263.
