NOTICE: 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
Section 418-01. In the event that As-Built data is required (the SJB does 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
the TPMS to normal operation. A new SJB is delivered in a manufacturing mode with 8 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)
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 Section 418-01.
2. Remove the steering column opening trim panel. For additional information, refer to Section 501-12.
3. Disconnect the SJB electrical connectors.
4. Remove the 2 harness pushpins from the SJB .
5. Using a suitable tool, lift the SJB release tab (away from the SJB bracket), slide the SJB (wiggling it 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.
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 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: 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 Section 501-14 for the remote transmitter
programming instructions.
NOTE: DTC B2276 may be set, indicating there are less than 2 transmitters programmed to the SJB . For
additional information, refer to Section 501-14.
NOTE: If the vehicle is equipped with IA , reset the keyless entry keypad code in the RFA module. Refer to
Keyless Entry Keypad Code Programming in Section 501-14.
Download the SJB configuration information from the scan tool. For additional information, refer to Section
418-01.
5. Train the tire pressure sensors. For additional information, refer to Section 204-04.
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 the 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.
