Yes
GO to I2.
No
REPAIR the DLC as necessary. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
I2 CHECK THE MS-CAN TERMINATION RESISTANCE
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the DLC C251-3, circuit 1847 (WH/OG), harness side and the DLC C251-11, circuit 1848 (PK/OG), harness side.
-

Yes
GO to I3.
No
GO to I5.
-------------------------------------------------
I3 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TO GROUND
-

(PK/OG), harness side and ground.
-
Are the resistances greater than 1,000 ohms?
Yes
CONNECT the negative battery cable. GO to I4.
No
GO to I16.
-------------------------------------------------
I4 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TO VOLTAGE
-
Ignition ON.
-
