Taurus AWD V6-3.5L (2009)
-
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 54 and 66 ohms?
Yes
GO to S3.
No
GO to S5.
-------------------------------------------------
S3 CHECK THE HS-CAN (+) AND HS-CAN (-) CIRCUITS FOR A SHORT TO GROUND
-
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 S4.
No
GO to S21.
-------------------------------------------------
S4 CHECK THE HS-CAN (+) AND HS-CAN (-) CIRCUITS FOR A SHORT TO VOLTAGE
-
Connect the battery ground 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.
-
Is the voltage greater than 6 volts?
Yes
REPAIR the circuit. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The HS-CAN has tested within specifications. Go To Pinpoint Test R to test for an intermittent network fault condition. See: Pinpoint Test R:
Intermittent No High Speed Controller Area Network (HS-CAN) Communication, Communication Can Be Intermittently
