F 350 2WD Super Duty V10-6.8L (2009)
No
GO to T9.
-------------------------------------------------
T6 CHECK THE HS-CAN TERMINATION RESISTOR WITH THE PCM DISCONNECTED
-
Disconnect: PCM C175b (Gasoline Engine) or C1232b (Diesel Engine).
-
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 108 and 132 ohms?
Yes
GO to T7.
No
GO to T8.
-------------------------------------------------
T7 CHECK THE HS-CAN CIRCUITS BETWEEN THE PCM AND THE DLC FOR AN OPEN
-
For gasoline engines, measure the resistance between the PCM C175b-11, circuit VDB04 (WH/BU), harness side and the DLC C251-6, circuit
VDB04 (WH/BU), harness side.
-
For gasoline engines, measure the resistance between the PCM C175b-23, circuit VDB05 (WH), harness side and the DLC C251-14, circuit
VDB05 (WH), harness side.
-
For diesel engines, measure the resistance between the PCM C1232b-34, circuit VDB04 (WH/BU), harness side and the DLC C251-6, circuit
VDB04 (WH/BU), harness side.
-
For diesel engines, measure the resistance between the PCM C1232b-47, circuit VDB05 (WH), harness side and the DLC C251-14, circuit
