Explorer 4WD V6-4.0L (2009)
The CAN has tested within specifications. Go To Pinpoint Test T to diagnose an intermittent HS-CAN fault. See: Pinpoint Test T: Intermittent No High
Speed Controller Area Network (HS-CAN) Communication, One Or More Modules Are Not Respond
-------------------------------------------------
S5 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 S6.
No
GO to S9.
-------------------------------------------------
S6 CHECK THE HS-CAN TERMINATION RESISTOR 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 between 108 and 132 ohms?
Yes
GO to S7.
No
GO to S8.
-------------------------------------------------
S7 CHECK THE HS-CAN CIRCUITS BETWEEN THE PCM AND THE DLC FOR AN OPEN
-
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.
-
Measure the resistance between the PCM C175b-23, circuit VDB05 (WH), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
