-------------------------------------------------
J10 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TOGETHER WITH THE SDARS MODULE
DISCONNECTED
-
Disconnect: SDARS Module C175b.
-
Measure the resistance between the DLC C251-3, circuit VDB06 (GY/OG), harness side and the DLC C251-11, circuit VDB07 (VT/OG), harness
side.
-
Is the resistance less than 5 ohms?
Yes
GO to J11.
