Power Distribution Module: Service and Repair
SMART JUNCTION BOX (SJB) REMOVAL/INSTALLATION
Removal
CAUTION: 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 appropriate scan tool. This
information must be downloaded into the new module after installation. See MODULE CONFIGURATION. See: Body and Frame/Body Control
Systems/Testing and Inspection/Programming and Relearning
-
The tire pressure monitoring system (TPMS) functionality is integral to the SJB.
-
The steps included in the SJB removal and installation procedure are critical to restoring the vehicle security and tire pressure monitoring systems
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. Upload the module configuration information from the SJB. See MODULE CONFIGURATION. See: Body and Frame/Body Control
Systems/Testing and Inspection/Programming and Relearning
NOTE: This step is necessary only if the SJB is being replaced.
2. Remove the floor console SJB cover.
3. Remove the transmission selector lever bezel from the floor console finish panel.
