-
Disconnect: SJB C2280b.
-
Measure the resistance between the DLC C251-3, circuit VDB06 (GY/OG), harness side and ground; and between the DLC C251-11, circuit
VDB07 (VT/OG), harness side and ground.
-
Are the resistances greater than 1,000 ohms?
Yes
CONNECT the negative battery cable. GO to X39.
No
If the vehicle is equipped with a Global Positioning System Module (GPSM), GO to X26.
