2026 Kia Models Emissions Data Collection TSB DC26

Kia Technical Service Bulletin (TSB) 261, issued in January 2026, details a mandatory Kia emissions data collection procedure for specific 2026 Kia models sold in California. This process, identified as DC26, involves extracting "in use monitoring performance tracking" emissions data from the Engine Control Unit (ECU) to ensure compliance with California Air Resources Board (CARB) requirements. This data collection is crucial for vehicles with a minimum of 3,000 accumulated miles that have not undergone recent ECU reprogramming or resetting. The procedure utilizes the Kia Diagnostic System (KDS) for data capture and electronic transmission, referencing TSB SST064 for additional details.

Important Warnings for Owners

Owners of 2026 Kia models should be aware of several critical points regarding this Kia emissions data collection:

• This data collection "DOES NOT apply to vehicles or dealers operating outside of California." It is specifically for vehicles sold and operated within California.
• If data collection is initiated after a specific model's line item is closed on the Dealer Communication System (DCS), the data collection is "subject to chargeback" to the dealer.
• "Submission of screenshots by KDS Feedback is no longer required for claim payment." The data will be transmitted electronically by KDS.

Conditions for Data Collection

Before performing the DC26 data collection, the vehicle must meet specific criteria:

• KDealer+ must show an open Data Collection code, such as "DC26XXXX" (the specific code depends on the model).
• The vehicle must have accumulated more than 3,000 miles on its odometer.
• The vehicle's repair history must not indicate a battery replacement/disconnection/reset or an ECU update within the last 3,000 miles. Such events would clear the IUMPR (In Use Monitor Performance Ratio) data.
• The vehicle must not have a "Malfunction Indicator Lamp (MIL) ON."

Data Collection Procedure Summary

California Kia dealers must perform this data collection whenever an affected vehicle is in the shop, prior to any campaign, maintenance, or repair activities. The process uses the KDS system and involves the following steps:

1. Locate Information: Open the engine compartment, find the Vehicle Emission Control Information label, and record the 11-digit "Group" number (e.g., JKMXV02.04X6).
2. Connect Diagnostic Tool: Connect the VCI-II to the OBD-II connector, typically found under the driver's side of the instrument panel.
3. Initiate KDS: Turn the ignition ON, power on the KDS tablet, and select 'KDS' from the home screen.
4. Vehicle Configuration: Confirm communication with the VCI and configure the vehicle using the 'AUTO VIN' feature.
5. Select IUMPR Function: From the 'More' section, pull up from the bottom of the screen to select the 'IUMPR' function.
6. Start Collection: Select 'IUMPR Start'. Ensure the KDS is connected to the internet and confirms an open DC 26 Data Collection for the vehicle.
7. Enter Information: If the vehicle has an open DC 26 Data Collection, the IUMPR Data Collection screen will appear. Accurately enter the Dealer Code, Mileage, Technician Name, Repair Order Number, and the Test Group (found on the underhood emission label).
8. Confirm VIN: A confirmation screen will display the entered information and the first page of collected IUMPR data. Confirm that the correct VIN was successfully captured by the initial KDS Auto VIN.
9. Transmit Data: Scroll down to find and select the 'Send' button to transmit the collected data to Kia's server.
10. Print Record: A confirmation message, "Test result has sent out successfully," will appear. Select 'Print' to obtain a record of the IUMPR data collection for the repair order.

Data Transmission Status and Troubleshooting

If the data transmission is unsuccessful, an error screen will indicate "Data transmission has failed." In such cases:

• Refer to the "Checking IUMPR Data Transmission Status" screen within KDS. If the status shows "pending," it means the data has been captured by KDS and will be automatically sent once an internet connection is restored.
• If the status is not "pending" or "sent," the entire collection procedure (steps 1-11) may need to be repeated.
• You can attempt to "Send All Pending" if an internet connection has just been established.

Warranty Information

This Kia emissions data collection procedure falls under specific warranty codes:

• N Code: N99
• C Code: C99

The TSB lists various Campaign IDs (e.g., DC26KA41, DC26SP21) corresponding to different 2026 Kia models and their specific repair descriptions. For instance, the Seltos (SP2 PE) 1.6L-T (SULEV) under Campaign ID DC26SP21 has a Causal P/N of "100CAEM999" and a Labor Op Code of "26SP2161" with an Op Time of 0.4 M/H.
