TECHNICAL SERVICE BULLETIN
IVT SOFTWARE LOGIC IMPROVEMENT
AND/OR IVT REPLACEMENT
SUBJECT:
This bulletin provides the procedure to update the Transmission Control Module (TCM) software logic and, if
necessary, replace the Intelligent Variable Transmission (IVT) assembly on certain 2019-2021MY model
vehicles listed in the chart below, which may exhibit an MIL ON with the DTC(s) listed below and a lack/delay
in acceleration due to transmission slippage. To correct this concern, if necessary, apply the improved
software logic to the CVT system using the KDS ECU Upgrade function as described in this bulletin and replace
the IVT assembly. For confirmation that the latest reflash has been applied to a vehicle you are working on,
verify the ROM ID using the table on page 4.
Description of DTC(s):
P0730 – Incorrect Gear Ratio
P0731 – Gear 1 Incorrect Ratio
P0741 – Torque Converter Clutch Circuit Performance or Stuck Off
P0867 – Transmission fluid pressure

 IMPORTANT
When replacing the IVT/CVT assembly, carefully follow the installation procedure outlined on KGIS
to complete the Auto Trans Adaptive Values learning procedure. Performing the ‘Oil-pressure
Characteristics Input’, refer to the IMPORTANT and NOTICE boxes on page 10. The adaptive values
learning procedure may require that the engine be shut OFF/ON multiple times until the values are
fully learned; start the vehicle, confirm the vehicle is idling in ‘Park’ without accelerator or brake
input and verify the ‘CVT Learning – P Range’ Current Data reads ‘ON’.
A Vehicle Diagnosis Number (VDN) must be created with at least one of the five (5) DTCs listed above,
prior to IVT replacement. If a VDN is not created, Parts Ordering and Warranty claim submission issues
WILL occur.

ECU Upgrade Procedure:
To correct this condition, the ECU should be reprogrammed using the KDS
download, as described in this bulletin.

 NOTICE
•
Confirm a fully charged battery (12.3 volts or higher is necessary) is used or utilize a fully
charged jump starter box connected to the battery.
•
Ensure the KDS is sufficiently charged at 60% or higher prior to reflash.
•
All ECU upgrades must be performed with the ignition set to the ‘ON’ position unless otherwise
stated.
•
Damaged VCI II units should not be used and promptly replaced.
•
Be careful not to disconnect the VCI-II connected to the vehicle during the ECU upgrade
procedure.
•
DO NOT start the engine during ECU upgrade.
•
DO NOT turn the ignition key ‘OFF’ or interrupt the power supply during ECU upgrade.
•
When the ECU upgrade is completed, turn the ignition ‘OFF’ and wait 10 seconds before
starting the engine.
•
ONLY use approved ECU upgrade software designated for the correct application.
 IMPORTANT
It is recommended to ALWAYS check the Electronic Parts Catalog (EPC) to locate the ECU Part
Number respective to Auto/Manual Mode ROM IDs. DO NOT reference the parts label affixed to
the ECU.

Before attempting an ECU upgrade on any Kia model, make sure to first determine whether the
applicable model is equipped with an immobilizer
security system. Failure to follow proper
procedures may cause the PCM to become inoperative after the upgrade and any claims associated
with this repair may be subject to chargeback.
