-
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 1,000 ohms?
Yes
CONNECT the negative battery cable. GO to I26.
No
If the vehicle is equipped with a 4X4 control module, GO to I21.
If the vehicle is not equipped with a 4X4 control module, GO to I22.
