SummaryPITSTOP: TECHNICAL OPERATIONS: EXTERNAL DAMAGE TO ULTRASONIC SENSOR: This Pitstop provides information related to Parking Distance Warning (PDW) alerts and repairs involving ultrasonic sensors. The PDW system alerts the driver while parking, by calculating distance based on the difference in signal transmission and reception times between the vehicle (ultrasonic sensor) and an object. The membrane film of the ultrasonic sensor is used for object detention and can be damaged by stone chips or foreign substances while driving. Damage to the cover of the ultrasonic sensor can also lead to damage to the internal circuit. As a result of this external damage, the PDW system may not receive the proper signal from the ultrasonic sensor. In some cases, the system may cause a false alarm, no alert, or phantom warnings by a “Warning Lamp’ to be displayed on the cluster. The ultrasonic sensor membrane film should be always inspected for external damage and if any part replacement should be treated as a general repair, not as a warranty claim repair for this concern. (Please note that this Pitstop only applies to models/trims that are equipped with the ultrasonic sensors.)

SummaryTECHNICAL 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.

SummaryPITSTOP: TECHNICAL OPERATIONS: DCU IDENTIFICATION AND DAIGNOSTIC AID - This Pitstop provides information on identifying the Data Connectivity Unit (DCU) in Kia vehicles equipped with Connected Car Navigation Cockpit (ccNC) and ccNC Lite head units, as well as a diagnostic aid when diagnosing Kia Connect concerns. When diagnosing non-operational Kia Connect concerns, under no circumstance should the DCU be swapped with a known good DCU from another vehicle. Doing so may result in inoperative Kia Connect services on either vehicle and may require the replacement of the known good DCU. If a DCU needs to be replaced, the recommendation is to always order a replacement unit (with the correct P/N) to ensure proper Kia Connect services operations using the newly installed/replaced DCU.
