SUBJECT:
SERVICE CAMPAIGN: 2005 SORENTO PASSENGER SEAT OCS REFLASH
This bulletin provides information relating to a service campaign on some 2005MY Sorento vehicles, with production dates ranging from 8/20/04 through 4/5/05. These vehicles may experience a problem with the Occupant Classification System (OCS). The OCS is an integral part of the passenger's seat cushion, and it may mis-classify the presence of certain adult passengers based on a combination of their weight, stature, body shape and position on the seat cushion. This condition prohibits the deployment of the passenger's air bag.
This bulletin provides information on how to update the Sorento OCS electronic control module located in the seat cushion with the reprogramming device called the "OC-Reprogramming Tool".
Note:
ONLY vehicles within the affected production date should be reflashed.
INSPECTION PROCEDURE:
1. Open hood and check for SC045 Campaign Completion Label on the left front inner fender well near the underhood fuse box.
^ If label exists, Campaign SC045 has been completed - NO FURTHER ACTION IS REQUIRED.
^ If Campaign SC045 label DOES NOT EXIST, continue to Step 2.
2. Open the hood; inspect for a yellow or orange paint dot on the inner fender panel.
^ If the paint dot exists, install the SC045 Campaign Completion Label. NO FURTHER ACTION IS REQUIRED.
^ If the paint dot DOES NOT EXIST, continue to the Reflash Procedure.
Note:
Campaign completion must be verified on the Warranty Coverage Validation screen, prior to performing repairs (KSS Main Menu - Option 3).
REFLASH PROCEDURE:
1. Slide the right front seat to the full forward position.
2. Remove the seat track cover from the left rear mounting stud of the right front seat. Grasp the cover and pull to the rear. The cover must be removed to access the OCS electrical connector.
3. Unplug the OCS wire harness connector and connect the OC-Reprogramming tool. Connect the OC-Reprogramming tool to the center console power outlet.
Note:
Turn the ignition key to the ACC position. DO NOT turn the key to the on position as it will set a stored DTC in the airbag system. Both GREEN and RED LED's will light up after 1-3 seconds. If the LED's do not power-up check the power outlet for proper operation.
The same OC-Reprogramming tool is used for the Sorento and the Spectra. After pressing the start button the tool will communicate with OCS computer, determine which vehicle it is and perform the proper reflash.
4. You are now ready to reflash the seat control module. Push the reflash start button on the tool to initiate the communication and reflashing with the tool.
5. The GREEN and RED LED lights will toggle back and fourth approximately 60 times during the reprogramming.
a. After a successful reprogram the GREEN LED will flash 3 quick blinks followed by a steady GREEN light.
b. If the RED LED flashes 3 quick blinks followed by a steady RED light the programming was unsuccessful:
^ Check the cable connections to the power supply and OCS seat connector. Verify the proper production date on the vehicle.
Note:
ONLY vehicles within the affected production date should be reflashed, vehicles produced before 8/20/04 have a different program in the seat module which does not require them to be updated.
6. After completion of reprogramming, turn the ignition key to the off position, disconnect the OC tool electrical connection at the power supply and OCS seat connector. Connect the OCS wire harness to the OCS connector under the right front passenger seat. Install the seat track trim cover as required.
7. Perform a functional check of the OCS system:
a. Turn the ignition switch off for 5 seconds.
b. Turn the ignition switch ON, monitor the tell-tale lamp on the center facia panel.
The "PASSENGER AIR BAG OFF" should light up initially, and then turn OFF and back ON.
c. Sit in the front passenger seat. If you weigh at least 105 lbs, the light should turn OFF.
d. Verify that the airbag/SRS warning lamp is off after initial bulb check.
8. Attach the SC045 Campaign Completion Label on the left front inner fender well near the underhood fuse box.
