This bulletin provides information to upgrade the ‘Engine Control Module’ (ECM) system software on certain
2025MY Carnival (KA4) vehicles equipped with 3.5L GDI Lambda Ⅲ engines produced from April 15, 2024
through November 27, 2024. The subject vehicles may have been produced with engine calibration that may
cause the vehicle to release air pollutants that exceed Federal and California standards and cause the
illumination of the Malfunction Indicator Lamp (MIL) with DTC P046100. These standards were established to
protect the public health and welfare from the dangers of air pollutants. To ensure compliance with emissions
regulations, follow the procedure outlined in this publication to apply the improved logic to the ‘Engine’ system
using the KDS ECU Upgrade function as described in this bulletin. Refer to SST081 for software upgrade
instructions using Kia Diagnostic System (KDS) tablet and VCI-II and confirm the Upgrade Event
Number/Name, ROM ID Information, and Manual Mode passwords (if applicable) on the applicable vehicle.
Before conducting the procedure, verify that the vehicle is included in the list of affected VINs.
