UPGRADE & DECAL INSTALLATION (CS2307)

 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) system on some 2012-2017MY Rio (UB) produced from February 28, 2012
through March 31, 2017 and 2018-2021MY Rio (SC) vehicles produced from June 1, 2017 through October 25,
2021, 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 ‘IBU-BCM’ system 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 and 4 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 (CS2307)
ECU Upgrade Procedure:

 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
The UB software update process REQUIRES the ignition to be in the ‘OFF’ position in both ‘Auto’
and ‘Manual’ modes. It is also REQUIRED that the power connector in the junction box be detached.
To correct this condition, the ECU should be reprogrammed using the KDS
download, as described in this bulletin.
