-
Is the voltage greater than 10 volts?
Yes
GO to M2.
No
VERIFY the Smart Junction Box (SJB) fuse 14 (10A) is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the Wiring Diagrams to
identify the possible causes of the circuit short. CLEAR the DTCs. REPEAT the network test with the scan tool.

M2 CHECK THE SDARS MODULE GROUND CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the SDARS module C3290-3, circuit GD115 (BK/GY), harness side and ground.
-
Is the resistance less than 5 ohms?
Yes
GO to M3.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.

M3 CHECK THE MS-CAN CIRCUITS BETWEEN THE SDARS MODULE AND THE DLC FOR AN OPEN
-
Measure the resistance between the SDARS module C3290-1, circuit VDB06 (GY/OG), harness side and the DLC C251-3, circuit VDB06
(GY/OG), harness side.
-
Measure the resistance between the SDARS module C3290-7, circuit VDB07 (VT/OG), harness side and the DLC C251-11, circuit VDB07
(VT/OG), harness side.
