Smart Junction Box (SJB): Removal

WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage to the module may result.

NOTE: Prior to the replacement of the module, it is necessary to upload the module configuration information to a scan tool. This information must be downloaded into the new Smart Junction Box (SJB) after installation. For additional information, refer to MODULE CONFIGURATION to carry out Programmable Module Installation (PMI).

NOTE: The Tire Pressure Monitoring System (TPMS) functionality is integral to the SJB.

NOTE: A new SJB is delivered in a "manufacturing mode" with 8 pre-set DTCs. A successful configuration of the SJB, then a successful TPMS sensor training, then a successful self-test including the clearing of all DTCs is required in order to clear the 8 pre-set manufacturing mode DTCs. The 8 manufacturing mode DTCs are:

B106D (Tire Pressure Monitor System [TPMS] Initiators Not Configured) - This DTC is present when the SJB is not configured, even on applications that are not equipped with initiators.
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)
B2A21 (One or More Configuration Files Missing or Corrupt)
C2780 (ECU in Manufacturer Sub-State)

NOTE: This step is only necessary if the SJB is being replaced.

Upload the module configuration information from the SJB into the scan tool. For additional information, refer to MODULE CONFIGURATION .
Turn the key to the OFF position.
Remove the RH A-pillar lower trim panel.
NOTE: It may be necessary to push the red lock tab downward and press the 2 black tangs inward to release the B+ connector.

Disconnect the 7 electrical connectors.
Remove the nut and the SJB.
