Flex FWD V6-3.5L (2010)
-
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.
-
Are the resistances greater than 1,000 ohms?
Yes
GO to V4.
No
GO to V21.
-------------------------------------------------
V4 CHECK THE HS-CAN (+) AND HS-CAN (-) CIRCUITS FOR A SHORT TO VOLTAGE
-
Connect: Negative Battery Cable.
-
Ignition ON.
-
Measure the voltage 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.
-
Are the voltages greater than 6 volts?
Yes
REPAIR the circuit in question. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The Controller Area Network (CAN) has tested within specifications. GO to Pinpoint Test U to diagnose an intermittent HS-CAN fault. See: Pinpoint
Test U: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, Communication Can Be Intermittently
-------------------------------------------------
V5 CHECK THE HS-CAN TERMINATION RESISTOR
-
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 V6.
