Installation
1. Position the SJB and install the 2 bolts.
-
Tighten the bolts to 2 Nm (18 lb-in).
2. Connect the SJB electrical connectors.
3. NOTE: If the SJB is not being replaced, this is the last step that is necessary.
Install the RH cowl panel side trim.
4. NOTE: When successful, this step provides the calibration necessary for the SJB operation and clears DTCs B106D, B2477 and B2A21. The
clearing of these DTCs indicates the calibration data has been successfully downloaded to the SJB.
NOTE: DTC B2276 may be set, indicating there are less than 2 transmitters programmed to the SJB. For additional information, refer to Doors,
Hood and Trunk &/or Locks.
Download the SJB configuration information from the scan tool to the SJB. For additional information, refer to Information Bus.
5. NOTE: When successful, this step clears DTCs B2868, B2869, B2870 and B2871. The clearing of these DTCs indicates the SJB has recognized
the tire pressure sensors during the training procedure.
Train the tire pressure sensors. For additional information, refer to Wheels and Tires.
6. NOTE: The SJB DTC C2780 does not clear if any other DTCs are still present in the SJB.
NOTE: This step is required to clear the SJB DTC C2780, allow the SJB to exit the manufacturing mode, and to make sure there are no other
concerns with the newly programmed SJB.
Carry out the SJB self-test (must include an on-demand self-test) and then repeat the self-test to confirm all SJB DTCs have been cleared.
7. Rotate the instrument panel dimmer switch from the full dim position to the dome ON position. This makes sure that all displays are visible under
all lighting conditions.
