Technical Service Bulletin: ECM Upgrade

A unique code assigned to each manufactured ECU (Engine Control Module). This code is used to identify the ECU model and software version.

Identifies the specific software version loaded onto the ECU.

The procedure using the scan tool to update the software in the ECU to a newer version.

The process of connecting the scan tool to the vehicle's diagnostic connector to initiate the ECU upgrade.

A specific KHyundai diagnostic scan tool for performing advanced diagnostics and programming.

A wireless communication technology that enables the scan tool to communicate with the vehicle's ECU.

Ensuring the battery has enough charge to prevent interrupts during the ECU upgrade process

Turning off accessories and headlights during the upgrade to conserve battery power.

A procedure that automatically updates the Electronic Control Unit (ECU) to the latest version, improving performance or addressing issues.

A process that manually upgrades the ECU to a specific version, used as a fallback if automatic upgrade fails.

A specific code that unlocks the ECU for a manual upgrade, ensuring it's the correct software version.

An event that triggers an ECU upgrade, usually linked to a specific issue or software update.

A diagnostic tool used for reading and clearing trouble codes in the vehicle.

A code indicating a fault or error within the vehicle's systems.

A critical part of the vehicle that controls various functions, like engine performance.

This bulletin provides the procedure to upgrade the ECM (Engine Control Module) software for certain Kia models.

A type of transmission that uses a clutch and gears, typically found in vehicles with manual or semi-automatic gearboxes.

The TSB addresses issues related to engine control, such as the protection against overheating during the DPF regeneration process and improving the engine control module's fault detection capability.

The affected vehicles are the 2023-24MY SELTOS (SP2i), SONET (QY), and CARENS (KY) models with a 1.5 VGT U2 engine.

A type of transmission that uses hydraulic pressure to change gears automatically, typically found in vehicles with automatic gearboxes.

The TSB requires the use of the KDS diagnostic device to perform the ECM upgrade.

The type of engine that is being used in the vehicle, e.g., 'D 1.5VGT U2' could refer to a 1.5-liter gasoline engine with variable geometry turbocharger.

The TSB specifies a table listing the ROM IDs for different components of the vehicle, including the engine, transmission, immobilizer, and ISG system.

A type of vehicle equipped with a gasoline engine and an intelligent manual transmission.

The type of vehicle, e.g., SELTOS, SONET, or a specific model name.

The TSB indicates that the previous TSB (KCE24-14-E080-SP2i, QY, KY) has been superseded by this bulletin and should be discarded.

The TSB highlights the importance of checking the ROM ID version on the vehicle before proceeding with the ECM upgrade.

The part number of the engine control module (ECM), which identifies the specific hardware part.

The TSB specifically mentions event #1101 for the CARENS (KY) vehicle, suggesting an update related to a specific vehicle function or component.

The new version of the ECM software program, typically assigned a unique number.

A specific engine configuration, typically used for identifying and referencing a vehicle part.

A unique identification number assigned to a specific engine configuration or part.

A code used to quickly identify a specific engine configuration.

A specific engine configuration, typically used for identifying and referencing a vehicle part.

A unique identification number assigned to a specific engine configuration or part.

A code used to quickly identify a specific engine configuration.

These refer to different types of transmissions, manual (iMT) and automatic (AT).

These abbreviations represent common features found in modern vehicle engines, like turbocharging, emissions standards, immobilizer systems, and other components.
