Smart Junction Box (SJB): Removal
CAUTION:
Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.
NOTE:
Prior to the removal of the module, it is necessary to upload the module configuration information to a scan tool. This information must be downloaded into the new SJB after installation. For additional information, refer to MODULE CONFIGURATION
.
- 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 into the scan tool. For additional information, refer to MODULE CONFIGURATION .
- Disconnect the battery. For additional information, refer to BATTERY, MOUNTING AND CABLES .
- Remove the RH A-pillar lower trim panel. For additional information, refer to INTERIOR TRIM AND ORNAMENTATION .
- Disconnect the 2 front SJB electrical connectors.
- Remove the SJB nut.
- Slide the SJB downward and position the SJB forward to access the rear electrical connectors.
- Disconnect the 6 rear SJB electrical connectors, the coaxial antenna and remove the SJB.
NOTE:
The tire pressure monitoring system (TPMS) functionality is integral to the SJB.
NOTE:
A new SJB is delivered in a manufacturing mode with 6 pre-set DTCs. These DTCs require that successful configuration of the SJB occurs, then successful TPMS sensor training occurs, then a successful self-test occurs, including clearing of DTCs. These are required in order to clear the 6 manufacturing mode DTCs. They are as follows:
NOTE:
To remove the coaxial antenna from the SJB, lift the red lock tab outward and press the black lever to release the connector.
