Subject: SERVICE ACTION: IVT SOFTWARE LOGIC IMPROVEMENT AND/OR IVT REPLACEMENT (SA424)
Group: ELE
Number: 200 (Rev 2, 07/23/2020)
Model: 2019-2021 Multiple Models with IVT
Date: June 2020
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.
Service Action Overview
This bulletin provides the procedure to improve the Transmission Control Module (TCM) logic and, if necessary, replace the Intelligent Variable Transmission (IVT) on 2019-2021 model year vehicles. Vehicles may exhibit a MIL (Malfunction Indicator Lamp) with the Diagnostic Trouble Codes (DTCs) listed below. The production ranges of the vehicles within the scope of this bulletin are listed in the table. 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, 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.
Diagnostic Trouble Codes (DTCs):
- P0730 - Incorrect Gear Ratio
- P0731 - Gear 1 Incorrect Ratio
- P0741 – Torque Converter Clutch Circuit Performance or Stuck Off
- P0867 – Transmission fluid pressure
Affected Vehicles:
| Model | Production Date |
|---|---|
| Forte (BDm) | 7/9/18 – 4/2/20 |
| Soul (SK3) | 11/24/18 – 4/17/20 |
| Seltos (SP2) | 11/20/19 – 4/10/20 |
A Service Action is a repair program without customer notification that is performed during the warranty period. Any dealer requesting to perform this repair outside the warranty period will require DPSM approval.

Flowchart Summary
Vehicle enters the process with a stored DTC (P0730, P0731, P0741, P0867).
YES: Perform TCM S/W Upgrade (Page 3).
NO: Perform TCM S/W Upgrade (Page 3).
After upgrade, initiate 'Resetting Auto Trans Adaptive Values' procedure.
Perform 'Oil-pressure Characteristics input (A/T Replacement)' procedure.
If FAILED (Blinking 'P' on cluster and DTC P160300): proceed to replace IVT/CVT Assembly.
If SUCCESSFUL: Complete 'Auto Trans Adaptive Values' relearn procedure and verify on KDS Data Analysis screen. Vehicle is released.
Vehicle DTC(s)
- P0730 - Incorrect Gear Ratio
- P0731 - Gear 1 Incorrect Ratio
- P0741 – Torque Converter Clutch Circuit Performance or Stuck Off
- P0867 – Transmission fluid pressure
After completing ‘Resetting Auto Trans Adaptive Values' on the KDS:
- P160300 – P-Learning Fail (CVT System)
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.
| Upgrade Event Name |
|---|
| 494. BDM NU 2.0MPI ATK CVT/IVT DRIVING PERFORMANCE IMPROVEMENT |
| 495. SK3 NU 2.0MPI ATK CVT/IVT DRIVING PERFORMANCE IMPROVEMENT |
| 496. SP2 NU 2.0MPI ATK CVT/IVT DRIVING PERFORMANCE IMPROVEMENT |
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 software designated for the correct model and model year.
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.
ECU Upgrade Steps:
- Connect VCI-II: Connect the VCI-II to the OBD-II connector, located under the driver's side of the instrument panel. (Note: ECU upgrade function on KDS operates wirelessly; USB cable is not necessary.)
- Power ON KDS: With the ignition ON, turn ON the KDS tablet. Select KDS from the home screen.
- Confirm Communication & Configure Vehicle: Confirm communication with VCI (A) and then configure the vehicle (B) using the AUTO VIN (C) feature. (Note: Perform DTC scan prior to initializing software upgrade.)
- Select ECU Upgrade: Select the ECU Upgrade option.
- Download Event: The KDS will check the server for recently uploaded Events and automatically download the relevant Upgrade Event (#494, #495, or #496). (Note: The vehicle must be identified in Vehicle Selection to download an Event.)
- Select Auto Mode: Select Auto Mode. (Caution: Do NOT attempt Manual Mode unless Auto Mode fails. Follow KDS instructions.)
- Select CVT System: Select the CVT system under the System selection menu. Touch ID Check (D) to confirm the latest update is available. Select the appropriate Upgrade Event and then select 'Upgrade'.
- Initiate Upgrade: The ECU upgrade will begin. The progress will appear on the bar graph. Part 1/2 downloads the event to VCI-II (E), and Part 2/2 upgrades the ECU (F). (Caution: Do not touch system buttons like 'Back', 'Home', etc. during the upgrade.)
- Handle Communication Failures: If a "Communication Fail" screen appears, verify VCI-II and KDS communication. Touch OK and restart from step 4. (Notice: If errors persist, do not disconnect KDS/VCI-II. Contact GIT America Help Desk at (888) 542-4371 or Techline.)
- Complete Upgrade: When instructed, turn the ignition OFF for ten (10) seconds, then back ON. Touch OK to continue.
- Finalize Procedure: Once the upgrade is complete, touch OK to finalize.
- DTC Check: When prompted, select YES to check for Diagnostic Trouble Codes (DTC) and erase any stored DTCs (e.g., EPS, ESC, TPMS) set during the upgrade.
Manual Upgrade Procedure
The manual upgrade should ONLY be performed if the automatic upgrade fails. If the automatic upgrade fails, turn the ignition OFF for about 10 seconds then place it back in the ON position to reset the control unit BEFORE performing manual upgrade.

Replacement Procedure
Replace the IVT assembly by referring to the "2.0 MPI NU (ATKINSON) ➡️ Intelligent Variable Transmission (IVT) System ➡️ Continuous Variable Transmission ➡️ Intelligent Variable Transmission ➡️ Repair procedures" chapter in the applicable Shop Manual on KGIS.
Transmission cooler requires flushing for Seltos (SP2) and Soul (SK3). Flushing for Forte (BDm) is not required as it features a cooler/heater system.
Adaptive Values Learning Procedure:
- Initiate the ‘Resetting Auto Trans Adaptive Values' procedure on the KDS.
- Perform the 'Oil-pressure Characteristics input (A/T Replacement)' procedure on the KDS, select 'OK'.
- Complete the ‘Auto Trans Adaptive Values' relearn procedure.
- On the KDS home menu, enter the CVT module 'Data Analysis' screen and confirm the Adaptive Values have learned.
Note: 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’.
