No
No modules are currently communicating on the HS-CAN. Go To Pinpoint Test s to diagnose no HS-CAN communication. See: Pinpoint Test S: No
High Speed Controller Area Network (HS-CAN) Communication, All Modules Are Not Responding
-------------------------------------------------
A2 VERIFY COMPUTERS AND CONTROL SYSTEMS INFORMATION PINPOINT TEST QA HAS BEEN CARRIED OUT
-
Verify that pinpoint test QA has been carried out.
-
Has pinpoint test QA been carried out?
Yes
GO to A3.
No
REFER to Computers and Control Systems Information, Pinpoint Tests, pinpoint test QA to diagnose no communication with the PCM.
-------------------------------------------------
A3 CHECK THE HS-CAN TERMINATION RESISTANCE
-
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
CONNECT the negative battery cable. GO to A5.
No
GO to A4.
-------------------------------------------------
A4 CHECK THE CAN CIRCUITS BETWEEN THE PCM AND THE DLC FOR AN OPEN
-
Measure the resistance between the PCM C175b-59, circuit VDB04 (WH/BU), harness side and the DLC C251-6, circuit VDB04 (WH/BU),
harness side.
-
Measure the resistance between the PCM C175b-58, circuit VDB05 (WH), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
