Taurus X AWD V6-3.5L (2009)
Power Distribution Module: Service and Repair
Smart Junction Box (SJB)
Removal
NOTICE: If the Smart Junction Box (SJB) is dropped, damage to the internal components may occur. A new SJB must be installed.
NOTICE: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.
NOTE: Prior to the replacement of the module, it is necessary to upload the module configuration information to the scan tool. This information must be
downloaded into the new module after installation. In the event that As-Built data is required (the SJB will not communicate), all Remote Keyless Entry
(RKE) devices must be programmed to the new SJB. A minimum of 2 devices are necessary to complete the configuration and turn off the flashing
interior lights.
NOTE: The Tire Pressure Monitoring System (TPMS) functionality is integral to the SJB.
NOTE: The steps included in the SJB removal and installation procedure are critical to restoring the vehicle security and the TPMS to normal operation.
A new SJB is delivered in a manufacturing mode with 7 pre-set DTCs related to the TPMS. To clear the DTCs, successful configuration of the SJB must
occur, followed by successful TPMS sensor training, and a successful self-test, including clearing of the DTCs.
The DTCs are as follows:
-
B106D (Tire Pressure Monitor System [TPMS] Initiators Not Configured)
-
B2477 (Module Configuration Failure)
-
B2868 (Left Front Tire Pressure Sensor Fault)
-
B2869 (Right Front Tire Pressure Sensor Fault)
-
B2870 (Right Rear Tire Pressure Sensor Fault)
-
B2871 (Left Rear Tire Pressure Sensor Fault)
-
C2780 (ECU in Manufacturer Sub-State)
1. NOTE: This step is necessary only if the SJB is being replaced.
Upload the module configuration information from the SJB.
2. Remove the steering column opening trim panel.
3. Disconnect the 6 SJB electrical connectors.
