Summary
PITSTOP: 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.

Owners of these vehicles have filed 225 complaints in the electrical category.
