Fusion FWD V6-3.0L (2009)
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
PINPOINT TEST U: INTERMITTENT NO HS-CAN COMMUNICATION, ONE OR MORE MODULES ARE NOT RESPONDING
DURING NETWORK TEST
NOTE: Various modules will set network DTCs during this test procedure. Clear the DTCs from all modules after the diagnostic procedure is complete.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
U1 CHECK THE DLC PINS FOR DAMAGE
-
Ignition OFF.
-
Disconnect the scan tool cable from the Data Link Connector (DLC).
-
Inspect DLC pins 6 and 14 for damage.
-
Are DLC pins 6 and 14 OK?
Yes
GO to U2.
No
REPAIR the DLC as necessary. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
U2 CHECK THE HS-CAN TERMINATION RESISTANCE
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the DLC C251-6, circuit VDB04 (WH/BU), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
-
Is the resistance between 54 and 66 ohms?
Yes
GO to U3.
No
Go To Pinpoint Test S. See: Pinpoint Test S: Intermittent No Medium Speed Controller Area Network (MS-CAN) Communication, One Or More
Modules Are Not Respo
-------------------------------------------------
U3 CHECK THE HS-CAN (+) AND HS-CAN (-) CIRCUITS FOR A SHORT TO GROUND
-
Measure the resistance between the DLC C251-6, circuit VDB04 (WH/BU), harness side and ground; and between the DLC C251-14, circuit
VDB05 (WH), harness side and ground.
