TECHNICAL SERVICE BULLETIN: SERVICE ACTION: BDC-BCM LOGIC IMPROVEMENT FOR DTC C1126 (SA579) - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information to improve the Body Domain Controller (BDC) – Body Control Module (BCM) operation logic on certain 2024MY EV9 (MV) vehicles produced from September 25, 2023 through February 21, 2024. The BDC Motor Control Unit (MCU) may incorrectly read the 12V auxiliary battery voltage as 0V. If this condition occurs, the tire pressure monitoring system (TPMS) light will blink for approximately one (1) minute and then remain illuminated, with the DTC C1126. This software upgrade may also be available via Over The Air (OTA) through Kia Connect if it has been activated.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
