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 a scan tool. This information must be downloaded into the new smart junction box (SJB) after installation. See MODULE CONFIGURATION , In the event that As-Built data is required (SJB will not communicate), all remote keyless entry (RKE) devices must be programmed to the new SJB. A minimum of 2 RKE devices are necessary to complete the configuration and turn off the flashing interior lights. 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 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. 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)
- Upload the module configuration information from the SJB. See MODULE CONFIGURATION
.NOTE:
- This step is necessary only if the SJB is being replaced.
- Remove the transmission selector lever bezel from the floor console finish panel.
- Remove the floor console SJB cover.
- Remove the floor console finish panel.
- Disconnect the 7 electrical connectors.
- Remove the 2 bolts and the SJB.
