Taurus X AWD V6-3.5L (2009)
REMOVE the jumper wire. GO to F3.
-------------------------------------------------
F3 CHECK CIRCUIT CLN28 (GN/BU) FOR AN OPEN
-
Disconnect: SJB C2280b.
-
Measure the resistance between the SJB C2280b-51, circuit CLN28 (GN/BU), harness side and the instrument panel dimmer switch C2065-5,
circuit CLN28 (GN/BU), harness side.
-
Is the resistance less than 5 ohms?
Yes
GO to F4.
No
REPAIR the circuit. TEST the system for normal operation.
-------------------------------------------------
F4 CHECK FOR CORRECT SJB OPERATION
-
Disconnect all the SJB connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the SJB connectors and make sure they seat correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new SJB. TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.

Normal Operation
The Smart Junction Box (SJB) provides voltage to the puddle lamps through circuit CLN25 (VT). The puddle lamps have separate ground circuits. The
LH exterior mirror is grounded through circuit GD133 (BK), and the RH exterior mirror is grounded through circuit GD148 (BK/YE).
-
DTC B2A39 (Puddle Lamp Output Circuit Open) - an on-demand DTC that sets when the SJB detects an open on the puddle lamp output circuit.
-
DTC B2A3A (Puddle Lamp Output Circuit Short To Ground) - a continuous and on-demand DTC that sets when the SJB detects a short to ground
