Explorer 4WD V6-4.0L (2009)
Yes
GO to Q3.
No
GO to Q5.
-------------------------------------------------
Q3 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 Q4.
No
GO to Q28.
-------------------------------------------------
Q4 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TO VOLTAGE
-
Connect: Negative Battery 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
The CAN has tested within specifications. Go To Pinpoint Test R to diagnose the intermittent MS-CAN fault. See: Pinpoint Test R: Intermittent No
Medium Speed Controller Area Network (MS-CAN) Communication, One Or More Modules Are Not Respo
-------------------------------------------------
Q5 CHECK THE MS-CAN TERMINATION RESISTOR
-
Measure the resistance between the DLC C251-3, circuit VDB06 (GY/OG), harness side and the DLC C251-11, circuit VDB07 (VT/OG), harness
side.
