Fusion FWD V6-3.0L (2009)
CONNECT the negative battery cable. GO to D5.
No
REPAIR the circuit in question. REACTIVATE the SRS. REFER to Air Bag Systems. CONNECT the negative battery cable. CLEAR the DTCs.
REPEAT the network test with the scan tool.
-------------------------------------------------
D5 CHECK FOR CORRECT RCM OPERATION
-
Disconnect all the RCM connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the RCM connectors and make sure they seat correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new RCM. REACTIVATE the SRS. REFER to Air Bag Systems. 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. REACTIVATE the SRS. REFER to
Air Bag Systems. CLEAR the DTCs. REPEAT the network test with the scan tool.

Normal Operation
The 4X4 control module 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 4X4 control module. Voltage to the 4X4 control module is supplied
by circuits CBP19 (BN/WH) and SBP15 (WH/RD). Ground is supplied by circuit GD126 (BK/WH).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
4X4 control module
PINPOINT TEST E: THE 4X4 CONTROL MODULE DOES NOT RESPOND TO THE SCAN TOOL
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
