Taurus X AWD V6-3.5L (2009)
-
Are the resistances less than 5 ohms?
Yes
GO to D4.
No
REPAIR the circuit in question. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
D4 CHECK FOR CORRECT 4X4 CONTROL MODULE OPERATION
-
Disconnect the 4X4 control module connector.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect the 4X4 control module connector and make sure it seats correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new 4X4 control module. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the
network test with the scan tool.

Normal Operation
The Restraints Control Module (RCM) communicates with the scan tool through the High Speed Controller Area Network (HS-CAN). Circuits VDB04
(WH/BU) (HS-CAN +) and VDB05 (WH) (HS-CAN -) provide the network connection to the RCM. The RCM shares the HS-CAN with the PCM, the
Accessory Protocol Interface Module (APIM), the Steering Effort Control Module (SECM), the ABS module, the 4X4 control module, the Occupant
Classification System Module (OCSM) and the Instrument Cluster (IC). Voltage for the RCM is provided by circuit CBP32 (GN/VT), and the RCM is
case grounded.
This pinpoint test is intended to diagnose the following:
