REMOVAL
| CAUTION | If the smart junction box (SJB) is dropped, damage to the internal components may occur. A new SJB must be installed. |
| 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 scan tool. This information must be downloaded into the new module after installation. For additional information, refer to MODULE CONFIGURATION article. 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 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 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)
- Upload the module configuration information from the SJB. For additional information, refer to «MODULE CONFIGURATION»(ref-293486) article.
- Remove the steering column cover. For additional information, refer to «INSTRUMENT PANEL AND CONSOLE»(ref-293483) article.
- Disconnect the 6 SJB electrical connectors.
- Remove the 2 harness pushpins from the SJB.
- Using a suitable tool, lift the SJB release tab (away from the SJB bracket), slide the SJB (wiggling it to the left) and remove.
- Disconnect the SJB B+ connector.
- If necessary, remove the 3 nuts and the SJB bracket.
INSTALLATION
- If necessary, install the 3 nuts and the SJB bracket. Tighten to 5 Nm (44 lb-in).
- Install the SJB. Connect the SJB B+ connector. Locate the SJB into the 3 tabs and slide the SJB (to the right) to engage the SJB release tab into the SJB bracket. Connect the 6 electrical connectors. Install the 2 harness pushpins into the SJB.
- Install the steering column cover.
- Download the SJB configuration information from the scan tool. For additional information, refer to «MODULE CONFIGURATION»(ref-293486) article.
- Train the tire pressure sensors. For additional information, refer to «WHEELS AND TIRES»(ref-293452) article.
- Carry out the SJB self-test (must include an on-demand self-test) and then repeat the self-test to confirm all DTCs have been cleared.
- Rotate the instrument panel dimmer switch from the full dim position to the dome ON position. This will make sure that all displays are visible under all lighting conditions.
REMOVAL AND INSTALLATION
- Remove the driver seat. For additional information, refer to «SEATING»(ref-293480) article.
- If equipped, position the dual climate control seat module (DCSM) aside.
- Disconnect the driver seat module (DSM) electrical connectors.
- Using a drill, remove the 2 rivets and the DSM.
- To install, reverse the removal procedure. Use the special tool to install the 2 rivets.
