UPGRADE & DECAL INSTALLATION (CS2304)

 NOTICE
This bulletin has been revised to include additional information. New/revised sections of this
bulletin are indicated by a black bar in the margin area.
This bulletin provides the procedure to upgrade the software logic of the Integrated Body Control Unit (IBU)
or Body Control Module (BCM), or Intelligent Integrated Platform Module (IPM) system on certain 20112015MY Sorento (XMa), 2016-2020MY Sorento (UMa), and 2021-2022MY Sorento (MQ4a) vehicles produced
within the dates outlined on page 10, which may not be equipped with an immobilizer. This logic upgrade will
add anti-theft ignition start logic to the vehicle's system operation which activates when the vehicle is locked.
Follow the procedure outlined in this publication to apply the improved logic to the ‘IPM-BCM-IBU’ using the
KDS ECU Upgrade function as described in this bulletin. For confirmation that the latest reflash has been
applied to a vehicle you are working on, verify the ROM ID using the table on pages 3-5 of this bulletin.
Window decals should also be applied to both front windows in accordance with the instructions on page 8 to
indicate this anti-theft S/W logic upgrade has been completed (unless a customer specifically requests, they
not be installed). An initial supply of window decals will be shipping directly to dealers. Should there be a
delay in receipt of this supply, please track any customers that may need window decals installation upon
receipt of the stickers.

CUSTOMER SATISFACTION: ANTI-THEFT S/W LOGIC UPGRADE

SUBJECT:

AND DECAL INSTALLATION (CS2304)

 IMPORTANT
Since the launch of this software upgrade, Kia has identified a compatibility issue involving
vehicles equipped with a remote start accessory which results in the activation of the burglar alarm
when the remote start is used. Therefore, we would like to delay installation of the software
upgrade until we can investigate and address this compatibility issue unless the customer is aware
of this issue and specifically requests the upgrade anyway.

 IMPORTANT
On certain XMa vehicles, it may be necessary to open the driver door and turn the
ignition key to the ‘OFF’ position after step 7 on page 7.
ECU Upgrade Procedure:
To correct this condition, the ECU should be reprogrammed using the KDS
download, as described in this bulletin.
