 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 improve the Transmission Control Module (TCM) logic and if
necessary, replace the Intelligent Variable Transmission (IVT) on 2019-2021MY vehicles which may
exhibit a MIL with the DTC(s) listed below. The production ranges of the vehicles within the scope of
this bulletin are listed in the table below. To correct this concern, apply the improved logic to the CVT
system using the KDS ECU Upgrade function as described in this bulletin and/or 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. Before conducting the procedure, verify the vehicle is
included in the list of affected VINs.
DTC(s):
P0730 – Incorrect Gear Ratio
P0731 – Gear 1 Incorrect Ratio

 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.

A fully charged battery is necessary before ECU upgrade can take place. It is
recommended that a battery charger is used in ECU mode during reflashing or
the use of a fully charged jump starter box connected to the battery.
DO NOT connect any other battery charger to the vehicle during ECU upgrade.
Ensure the KDS or GDS is sufficiently charged prior to reflash.
All ECU upgrades must be done with the ignition key in the ‘ON’ position.
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 model and
model year.

 NOTICE
Before attempting an ECU upgrade on any Kia model, make sure to first determine
whether the particular 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.
