Ranger 4WD V6-4.0L (2009)
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
I9 CHECK THE HS-CAN (+) AND HS-CAN (-) CIRCUITS FOR A SHORT TOGETHER
-
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
GO to I11.
No
GO to I10.
-------------------------------------------------
I10 CHECK THE HS-CAN CIRCUITS FOR AN OPEN AT THE DLC
-
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 greater than 10,000 ohms?
Yes
REPAIR the DLC or the circuit in question. CONNECT the negative battery cable. 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.
-------------------------------------------------
I11 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
