-
Is the resistance less than 5 ohms?
Yes
GO to V3.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
V3 CHECK THE MS-CAN CIRCUITS BETWEEN THE HVAC MODULE AND THE DLC FOR AN OPEN
-

C2356a-25 (DATC), circuit VDB06 (GY/OG), harness side and the
Data Link Connector (DLC) C251-3, circuit VDB06 (GY/OG), harness side.
-
Measure the resistance between the HVAC module C2357a-26 (manual), C228a-26 or
C2356a-26 (DATC), circuit VDB07 (VT/OG), harness side and the DLC C251-11, circuit VDB07 (VT/OG), harness side.
-
Are the resistances less than 5 ohms?
Yes
