Sedona Airbag Control Unit Logic Change

This bulletin provides information relating to a running change in the Sedona Airbag Control Unit (ACU) logic which is being made available to prior purchasers as a customer satisfaction issue. This change was made to address an airbag deployment in a 5 mph bumper impact procedure conducted by the Insurance Institute for Highway Safety (IIHS).

The IIHS procedure involves an unoccupied vehicle with no test dummies hitting a 320,000 lb. barrier at 5 mph. It is not a safety test. The procedure is only used to estimate repair costs. During this procedure, the airbags in the Sedona deployed, causing the alleged repair costs for the Sedona to increase. Kia engineers concluded that the deployment was unique to the IIHS procedure, and does not reflect what happens in real world collisions.

However, to eliminate the possibility that a deployment might occur the next time IIHS conducted it's procedure, and to thus prevent confusion among our customers regarding the significance of the deployment, Kia initiated a production running change in the ACU logic software from 2/20/02. Sedona owners have been informed of this change.

For owners of Sedona models produced before the ACU logic change, who now also request that their vehicle's ACU logic be changed, a reprogramming card has been made available for the Hi-Scan Pro to download the new software into the requesting owner's vehicles. Use the procedure to reprogram the ACU.

REPROGRAMMING PROCEDURE:





1. Remove the program card from the upper slot on the Hi-Scan Pro tool and insert the Sedona reprogramming card.





2. Connect the Hi-Scan Pro tool to the OBD II connector under the dash on the driver's side.

3. Turn ignition key to the "on" position.





4. Turn Hi-Scan Pro tool on, select option 02. "SEDONAAIR-BAG REPROGRAM" from the Hi-Scan Pro menu screen and press the "ENTER" key.





5. Select option 01. "SEDONAAIR-BAG [AUTO TEST]" and press the "ENTER" key.





6. At the prompt, enter password "0525" and press the "ENTER" key.

Note:
If vehicle airbag system has already been reprogrammed, the Hi-Scan Pro tool will show you a message stating "ALREADY REPROGRAMMED".














Reprogramming will proceed on the Hi-Scan Pro screens as shown.

7. After "Reprogramming Completed!" message is received, turn ignition key to the "OFF" position, turn Hi-Scan Pro tool off and disconnect from the OBDII connector.

8. Turn ignition key to the "ON" position. Airbag light on the dash should blink six times and stay off.

AFFECTED PRODUCTION RANGE:

All Sedona models with production dates prior to 2/20/02.
