Mariner 4WD V6-3.0L (2010)
-
Is the voltage greater than 10 volts?
Yes
GO to E4.
No
VERIFY the Smart Junction Box (SJB) fuse 31 (10A) is OK. If OK, REPAIR the circuit in question. REPOWER the SRS. REFER to Restraint Systems.
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. See: Diagrams/Electrical Diagrams/Diagrams By Number
-------------------------------------------------
E4 CHECK THE HS-CAN CIRCUITS BETWEEN THE RCM AND THE DLC FOR AN OPEN
-
Ignition OFF.
-
Measure the resistance between the RCM C2041b-10, circuit VDB04 (WH/BU), harness side and the DLC C251-6, circuit VDB04 (WH/BU),
harness side.
-
Measure the resistance between the RCM C2041b-9, circuit VDB05 (WH), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
-
Are the resistances less than 5 ohms?
Yes
GO to E5.
No
REPAIR the circuit in question. REPOWER the SRS. CLEAR the DTCs. REPEAT the network test with the scan tool.
