-
Disconnect: IC C220.
-
Measure the resistance between the DLC C251-6, circuit VDB04 (WH/BU), harness side and ground; and between the DLC C251-14, circuit
VDB05 (WH), harness side and ground.
-
Are the resistances greater than 5,000 ohms?
Yes
CONNECT all modules. CONNECT the negative battery cable. GO to T36.
No
If the vehicle is equipped with a diesel engine, GO to T27.
If the vehicle is not equipped with a diesel engine, REPAIR the circuits. CONNECT all modules. CLEAR the DTCs. REPEAT the network test with the
scan tool.
