GO to L2.
No
VERIFY the Battery Junction Box (BJB) fuse 47 (10A) is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the Wiring Diagrams to
identify the possible causes of the circuit short See: Diagrams/Electrical Diagrams/Diagrams By Number. CLEAR the DTCs. REPEAT the network test
with the scan tool.
-------------------------------------------------
L2 CHECK THE DC/DC GROUNDS
-
Ignition OFF.
-
Disconnect: Negative Battery Cable .
-
NOTE: Do not disconnect the DC/DC ground eyelet C1457c. The measurement is taken between the negative battery eyelet and chassis ground.
-
Measure the resistance between the DC/DC C1457c-1, circuit GD108 (BK/VT), harness side and ground.
-
Is the resistance less than 5 ohms?
Yes
GO to L3.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
L3 CHECK THE HS-CAN CIRCUITS BETWEEN THE DC/DC AND THE DLC FOR AN OPEN
-
Measure the resistance between the DC/DC C1457d-9, circuit VDB04 (WH/BU), harness side and the DLC C251-6, circuit VDB04 (WH/BU),
harness side.
-
Measure the resistance between the DC/DC C1457d-6, circuit VDB05 (WH), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
