Focus L4-2.0L (2009)
-
Ignition OFF.
-
NOTE: Measurements are taken with the fuses installed.
-
Measure the voltage between the SJB fuse 5 (10A) and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to J2.
No
VERIFY the SJB fuse 5 (10A) is OK. If OK, GO to J4. If not OK, REFER to the Wiring Diagrams to identify the possible causes of the circuit short.
REPEAT the network test with the scan tool.
-------------------------------------------------
J2 CHECK THE SJB GROUND CIRCUITS FOR AN OPEN
-
Disconnect: Negative Battery Cable.
-
Disconnect: SJB C2280d.
-
Measure the resistance between the SJB C2280d-8, circuit GD133 (BK), harness side and ground; and between the SJB C2280d-12, circuit
GD133 (BK), harness side and ground.
-
Are the resistances less than 5 ohms?
Yes
GO to J3.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
J3 CHECK THE MS-CAN CIRCUITS BETWEEN THE SJB AND THE
DLC FOR AN OPEN
-
Disconnect: SJB C2280b.
-
Measure the resistance between the SJB C2280b-37, circuit VDB06 (GY/OG), harness side and the Data Link Connector (DLC) C251-3, circuit
VDB06 (GY/OG), harness side.
