Notice on KDS Satisfaction Survey Results

January 5^th, 2026

Dear Kia Family,

Thank you for your continued cooperation in actively supporting our diagnostic solutions and service operations.

From April 28 to August 31, 2025, we conducted a KDS usage satisfaction survey over approximately four months, targeting global service technicians.

This survey was carried out to gather feedback on diagnostic functions, VCI modules, DTC guides, and technical information integration, with the aim of improving the quality of our products and services in the future.

■ Key Feedback and Areas for Improvement

The survey identified the following common areas for improvement.

Classification	Before	After
Sensor Data Search Function	No separate search function	Sensor data search function added
Application of the Actuation Test Guide	Only operational status information available	Function description and indication of status after operation
Include Actuation Test Video	No separate function description for forced actuation items	Detailed descriptions and video guides for 9 BMS system functions (Further items will be added over time)
Add Favorites Feature to S/W Management	Labeled as “All”, No favorites feature available	Favorite feature and filter function added
Improvement of ECU Upgrade Error Guide	Insufficient detailed description	Key checkpoints and FAQ links provided

Beyond the improvements listed above, we will continue validating and refining diagnostic guide content and its connectivity.

■ Future Improvement Plan

Based on the survey results, we will continue to drive improvements throughout the first quarter of 2026 in the following directions.

Classification	Before	After
DTC Grade Indication	No separate indication for DTC grade	Display DTC grade and show detailed information when clicked
VCI Connection	Issues with VCI recognition speed and connection latency	Improved to allow immediate changes after saving VCI information
ECU Upgrade Entry Condition	Insufficient guidance on prerequisites before performing the function.	Strengthen prerequisite checks and provide visual indicators
Detailed Sensor Data Information	Lack of detailed information on labels and displayed values	Enhance sensor data description details and assess diagnostic visualization feature

In addition to the above plans, we will continue ongoing improvements as follows:

• Gradual enhancement of diagnostic functions and DTC guide contents
• Continuous verification and improvement of diagnostic guides and links
• Strengthening usage guides and new feature instructions for technicians
• Operation of a continuous feedback collection system for global technicians

We would like to express our sincere gratitude to everyone who participated in this survey. Moving forward, we will continue to reflect on the voices from the field and strive to provide a more stable and efficient diagnostic environment.

Thank you.
