Removal

NOTICE : 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 Smart Junction Box (SJB) after installation. For additional information, refer to Section 418-01.
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 steps are required in order to clear the 6 pre-set manufacturing mode DTCs. The 6 pre-set manufacturing mode DTCs are as follows:

• 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. NOTE : If the SJB is being replaced, follow this step. If the SJB is not being replaced, go to Step 2.
   Upload the module configuration information from the SJB into the scan tool. For additional information, refer to Section 418-01.

2. Remove the RH A-pillar lower trim panel. For additional information, refer to Section 501-05.

3. NOTE : The SJB electrical connector levers must click into a fully released position before they can be removed.
   Disconnect the 2 front SJB electrical connectors.

4. Remove the SJB nut.

5. Slide the SJB downward and position the SJB forward to access the rear electrical connectors.

6. NOTE: The SJB electrical connector levers must click into a fully released position before they can be removed.
   Disconnect the 6 rear SJB electrical connectors and remove the SJB.

Installation

NOTE : When a new SJB is installed, all customer Remote Keyless Entry (RKE) transmitters may be required to be present in order to program the RKE transmitters to the new SJB.

1. NOTICE : Make sure the wiring harnesses are correctly routed. Pinching the wiring harnesses between the SJB and the mounting surface may cause damage to the wiring harness.
   NOTE: Do not remove the water shield from the new SJB.
   NOTE: It is not necessary to remove the external TPMS/RKE antenna from the SJB. Make sure it is securely fastened in the SJB housing clips and that it is properly connected to the SJB connection on the rear of the SJB.
   NOTE: The SJB electrical connector levers must click into a fully closed (connected) position when installing.
   Connect the 6 rear SJB electrical connectors and install the SJB.

2. Install the SJB nut.

3. Tighten to 6 Nm (53 lb-in).

4. NOTE: The SJB electrical connector levers must click into a fully closed (connected) position when installing. Connect the 2 front SJB electrical connectors by fully engaging the levers until an audible click is heard.

5. NOTE: If the SJB was not replaced, the procedure is completed after this step. If the SJB was replaced, follow steps 4-7.
   Install the RH A-pillar lower trim panel. For additional information, refer to Section 501-05.

6. NOTE: When successful, this step also programs the RKE transmitters into the new SJB. In the event the RKE transmitters do not program to the new SJB, all of the RKE transmitters will need to be present and refer to Section 501-14, Remote Keyless Entry Transmitter Programming. This action will program the RKE transmitters into the new SJB.
   Download the SJB configuration information from the scan tool into the new SJB. For additional information, refer to Section 418-01.

7. Train the tire pressure sensors. For additional information, refer to Section 204-04.

8. NOTE: This step is required to clear DTC C2780, allow the SJB to exit the manufacturing mode, and to be sure there are no other concerns (DTCs) with the newly programmed SJB.
   NOTE: DTC C2780 will not clear if any other DTCs are present in the SJB.
   Carry out the SJB self-test (must include an on-demand self-test). Clear the DTCs and then retrieve the DTCs to confirm all DTCs have been cleared.
