B2A21 (One or More Configuration Files Missing or Corrupt)
-
C2780 (ECU in Manufacturer Sub-State)
1. NOTE: This step is necessary only if the SJB is being replaced.
Upload the module configuration information from the SJB. For additional information, refer to Information Bus.
2. Remove the steering column opening trim panel. For additional information, refer to Instrument Cluster / Carrier &/or Interior Moulding / Trim.
3. Disconnect the SJB electrical connectors.
4. Remove the 2 harness pushpins from the SJB.
5. Using a suitable tool (such as a flat-blade pocket screwdriver), lift the SJB release tab away from the SJB bracket, slide the SJB to the left and
remove.
6. Disconnect the SJB B+ (battery lead, part of the 14290 harness) connector.
7. If necessary, remove the 3 nuts and the SJB bracket.
Installation
1. NOTE: Align the SJB bracket to the upper 2 mounting studs, then rotate the bracket onto the lower mounting stud.
If necessary, install the 3 nuts and the SJB bracket.
2. Install the SJB.
-
Connect the SJB B+ (battery lead, part of the 14290 harness) connector.
-
Position 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 electrical connectors.
-
Install the 2 harness pushpins into the SJB.
3. NOTE: If the SJB was not replaced, this is the last step that is necessary.
Install the steering column opening trim panel.
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 new SJB.
NOTE: The RKE transmitter portion of the Integrated Keyhead Transmitter (IKT) key is automatically transferred during Programmable Module
Installation (PMI). Passive Anti-Theft System (PATS) programming is not necessary. If As-Built data is required during PMI, all (IKT or fob)
remote transmitters must be programmed to the new SJB. Cycling the ignition to run for 6 seconds with each IKT programs the RKE function of
the IKT key. For additional information, refer to Doors, Hood and Trunk &/or Locks for the remote transmitter programming instructions.
NOTE: DTC B2276 may 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. 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: DTC C2780 does not clear if any of the pre-set DTCs are still present in the SJB. When successful, this step clears DTC C2780.
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.
7. Rotate the instrument panel dimmer switch from the full dim position to the dome ON position to calibrate the switch. This makes sure that all
displays are visible under all lighting conditions.
