Flex FWD V6-3.5L (2010)
GO to W3.
No
GO to Pinpoint Test X. See: Pinpoint Test X: No Medium Speed Controller Area Network (MS-CAN) Communication, All Modules Are Not
Responding
-------------------------------------------------
W3 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TO GROUND
-
Measure the resistance between the DLC C251-3, circuit VDB06 (GY/OG), harness side and ground; and between the DLC C251-11, circuit
VDB07 (VT/OG), harness side and ground.
-
Are the resistances greater than 1,000 ohms?
Yes
GO to W4.
No
GO to Pinpoint Test X.
-------------------------------------------------
W4 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TO VOLTAGE
-
Connect: Negative Battery Cable.
-
Ignition ON.
-
Measure the voltage between the DLC C251-3, circuit VDB06 (GY/OG), harness side and ground; and between the DLC C251-11, circuit VDB07
(VT/OG), harness side and ground.
-
Is the voltage greater than 6 volts?
Yes
REPAIR the circuit in question. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
GO to W5.
-------------------------------------------------
W5 CHECK FOR RESTORED NETWORK COMMUNICATION WITH THE SJB DISABLED
-
Disconnect: Smart Junction Box (SJB) Fuse 5 (10A).
-
Enter the following diagnostic mode on the scan tool: Network Test.
-
Repeat the network test.
-
Do all other MS-CAN modules pass the network test?
