Fusion FWD V6-3.0L (2009)
CONNECT the negative battery cable. GO to A5.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
A5 CHECK FOR CORRECT PCM OPERATION
-
Disconnect all the PCM connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the PCM 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 PCM. REFER to Computers and Control Systems Information. CONNECT all modules. CONNECT the negative battery cable.
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. CONNECT all modules.
CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.

By Number
Normal Operation
The Transmission Control Module (TCM) 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 TCM. The FNR5 transaxle TCM and the 6-speed
transaxle TCM both communicate on the HS-CAN. Voltage for the TCM is provided by circuits CBP18 (GY/OG), SBP07 (WH/RD) and SBB16
(VT/RD). Circuit GD120 (BK/GN) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
TCM
PINPOINT TEST B: THE TCM DOES NOT RESPOND TO THE SCAN TOOL
NOTICE: Use the correct probe adapter(s) when taking 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.
