TECHNICAL SERVICE BULLETIN: VOLUNTARY SERVICE CAMPAIGN: PDC LOGIC IMPROVEMENT AND PRA REPLACEMENT FOR DTC PIB7700 (SC343) - 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 upgrade the Powernet Domain Control ‘PDC’ system software on certain 2025MY EV6 (CV1a) vehicles produced from December 10, 2024 through June 24, 2025, built at a Kia assembly plant in the US. Due to a PDC software logic error in the subject vehicle, the pre-charge resistor may become damaged if the vehicle is abnormally turned ‘OFF’ (e.g. turned ‘OFF’ while the gear selection is in ‘Neutral’). If the pre-charge resistor becomes damaged, the vehicle may not go into ‘READY’ mode. Customers may experience the illumination of the service warning light, and the vehicle may set DTC P1B7700. If DTC P1B7700 is stored, technicians are to replace the PRA before upgrading the ‘PDC’ software.
