Kia has released Technical Service Bulletin (TSB) 238, identified as Service Action SA498, to address a specific Engine Control Module (ECM) logic issue affecting certain 2023 Kia Sportage vehicles. This service action provides a software update to correct conditions that may cause the Malfunction Indicator Lamp (MIL), commonly known as the 'Check Engine' light, to illuminate.
The issue specifically pertains to the Kia Sportage P0456 P013E diagnostic trouble codes. Owners who experience these codes should be aware that a software improvement is available through their authorized Kia dealer.
Symptoms
Owners of affected 2023 Kia Sportage vehicles may observe the following symptoms:
- The Malfunction Indicator Lamp (MIL) or 'Check Engine' light illuminates on the dashboard.
- Diagnostic Trouble Code (DTC) P0456 is stored in the ECM.
- Diagnostic Trouble Code (DTC) P013E is stored in the ECM.
Fault Codes / DTCs
This service action specifically addresses the following diagnostic trouble codes:
| Code | Description | Module |
|---|---|---|
| P0456 | Evaporative Emission System / Leak Detected (very small leak) | ECM |
| P013E | O2 Sensor Delayed Response / Rich to Lean Bank 1 Sensor 2 | ECM |
Diagnosis / Trigger Conditions
This condition affects 2023 Kia Sportage (NQ5/NQ5a) models equipped with the Theta 2.5L GDI engine and an 8-speed automatic transmission. These vehicles were produced within specific date ranges: December 15, 2021, to April 15, 2022, for NQ5 models, and January 25, 2022, to April 25, 2022, for NQ5a models.
The illumination of the MIL and the storage of DTC P0456 or P013E are triggered by an identified logic issue within the Engine Control Module's software. Technicians will verify if a vehicle is affected by checking its current ROM ID against a table provided in the bulletin, which lists both previous and new ROM IDs for various ECU part numbers like 39100-2S210, 39100-2S215, and others.
Repair Procedure Summary
The repair involves updating the software logic of the Engine Control Module (ECM) using the Kia Diagnostic System (KDS) ECU Upgrade function. The process is as follows:
- Preparation: Ensure the vehicle's battery is fully charged (at least 12.3 volts) or connected to a jump starter. The KDS unit itself must be at least 60% charged.
- Connection: Connect the VCI-II interface to the vehicle's OBD-II connector, typically located under the driver's side of the instrument panel.
- KDS Setup: Turn on the KDS tablet, select 'KDS' from the home screen, and then choose 'ECU Upgrade'. Confirm communication with the VCI and configure the vehicle using the 'AUTO VIN' feature.
- Software Download: The KDS will automatically download Upgrade Event #617, which contains the necessary ECM software update.
- Upgrade Execution: Select 'Auto Mode' and then the 'ENGINE' system. Confirm the latest update is available and proceed with the upgrade. The KDS will perform the upgrade in two parts.
- Post-Upgrade: Once the upgrade is complete, turn the ignition 'OFF' for 10 seconds, then back 'ON'. Select 'YES' when prompted to check for and erase any Diagnostic Trouble Codes (DTCs) that may have been set during the upgrade (e.g., EPS, ESC, TPMS).
- Final Check: Start the engine to confirm normal vehicle operation. If the automatic upgrade fails, a manual upgrade procedure is available, requiring specific passwords based on the ECU part number.
Required Tools or Parts
To perform this service action, the following tools are required:
- Kia Diagnostic System (KDS): This specialized diagnostic tool is essential for performing the ECU software upgrade.
- VCI-II Interface: Used to connect the KDS to the vehicle's OBD-II port.
- Fully Charged Vehicle Battery: A stable power supply is critical during the upgrade process to prevent interruptions.
Important Warnings for Owners
Kia has provided several critical notices regarding this service action:
