F 150 4WD V8-4.6L VIN 8 (2010)
-
Are the resistances less than 5 ohms?
Yes
REPAIR the DLC or REPAIR the circuit in question. CONNECT all modules. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
A capacitor internal to a module may still be draining, causing irregular resistance readings. WAIT 5 minutes. REPEAT the pinpoint test.
-------------------------------------------------
Y11 CHECK THE HS-CAN (+) AND HS-CAN (-) CIRCUITS FOR A SHORT TOGETHER WITH THE PCM DISCONNECTED
-
Disconnect: PCM C175b.
-
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 less than 5 ohms?
Yes
If the vehicle is equipped with a Transmission Control Module (TCM), GO to Y12.
If the vehicle is not equipped with a TCM, GO to Y13.
No
CONNECT the negative battery cable. GO to Y31.

Y12 CHECK THE HS-CAN (+) AND HS-CAN (-) CIRCUITS FOR A SHORT TOGETHER WITH THE TCM DISCONNECTED
-
Disconnect: TCM C1575.
-
Measure the resistance between the DLC C251-6, circuit VDB04 (WH/BU), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
