-
Is the voltage greater than 10 volts?
Yes
GO to O3.
No
VERIFY the Smart Junction Box (SJB) fuse 18 (10A) is OK. If OK, REPAIR the circuit. 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.

O4 CHECK THE MS-CAN CIRCUITS BETWEEN THE PAM AND THE DLC FOR AN OPEN (RADAR)
-
Measure the resistance between the PAM C4226-4, circuit VDB06 (GY/OG), harness side and the DLC C251-3, circuit VDB06 (GY/OG),
harness side.
-
