-
Are the resistances greater than 1,000 ohms?
Yes
CONNECT the battery ground cable. GO to U35.
No
GO to U27.
-------------------------------------------------
U27 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TO GROUND WITH THE IC DISCONNECTED
-
Disconnect: IC C220.
-
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.
