Fusion FWD L4-2.5L Hybrid (2010)
-
Measure and record the voltage at the battery.
-
Disconnect: SJB C2280g.
-
Measure the voltage between the SJB C2280g-1, circuit SDC02 (RD), harness side and ground.
-
Is the voltage within 0.2 volt of the recorded battery voltage?
Yes
GO to L5.
No
REPAIR the circuit for high resistance. CLEAR the DTCs. REPEAT the self-test.
-------------------------------------------------
L5 CHECK THE SJB GROUND CIRCUITS
-
Disconnect: Negative Battery Cable.
-
Disconnect: SJB C2280d.
-

GD126 (BK/WH), harness side and ground
-
Is the resistance less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to L6.
No
REPAIR the circuit for high resistance. CONNECT the negative battery cable. TEST the system for normal operation.
-------------------------------------------------
L6 CHECK FOR CORRECT SJB OPERATION
