-
Is the voltage greater than 10 volts?
Yes
GO to E3.
No
VERIFY the Smart Junction Box (SJB) fuse 32 (10A) is OK. If OK, REPAIR the circuit. 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.
-------------------------------------------------
E3 CHECK THE RCM CASE GROUND
-
Ignition OFF.
-
Disconnect: Negative Battery Cable .
-
Measure the resistance between the RCM case and a good chassis ground.
-
Is the resistance less than 5 ohms?
Yes
GO to E4.
No
REPAIR the RCM case ground as necessary. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
E4 CHECK THE HS-CAN CIRCUITS BETWEEN THE RCM AND THE DLC FOR AN OPEN
-
Measure the resistance between the RCM C310b-10, circuit VDB04 (WH/BU), harness side and the Data Link Connector (DLC) C251-6, circuit
VDB04 (WH/BU), harness side.
-
Measure the resistance between the RCM C310b-9, circuit VDB05 (WH), harness side and the DLC C251-14, circuit VDB05 (WH), harness side.
-
Are the resistances less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to E5.
No
