Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
