Taurus AWD V6-3.5L (2009)
GO to T3.
No
Go To Pinpoint Test R. See: Pinpoint Test R: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, Communication Can
Be Intermittently
-------------------------------------------------
T3 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 T4.
No
Go To Pinpoint Test R. See: Pinpoint Test R: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, Communication Can
Be Intermittently
-------------------------------------------------
T4 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TO VOLTAGE
-
Connect the battery ground 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. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
GO to T5.
-------------------------------------------------
T5 CHECK FOR RESTORED NETWORK COMMUNICATION WITH THE SMART JUNCTION BOX (SJB) DISABLED
NOTE: When re-running the network test, the network test application must be first closed or the screen display will revert back to the prior run network
test results.
-
Disconnect: SJB Fuse 5 (10A).
-
Enter the following diagnostic mode on the scan tool: Network Test.
-
Repeat the network test.
-
Do all other modules pass the network test?
