An update to Bulletin #22-NA-038 has been released that covers changes for several Customer Concern Not Duplicated (CCND) labor operations that address screen conditions and audio system issues on 2022-2027 GM passenger cars and trucks (excluding Chevrolet LCF models). The updated bulletin provides a list of labor operations along with descriptions and guidelines for CCND conditions related to a variety of vehicle systems.
In the Infotainment, Telematics & OnStar systems group, the bulletin outlines a number of updates that include labor operations that were being used inconsistently or inappropriately for multiple conditions.
TIP: Be sure to use the correct system-specific labor codes when addressing concerns with instrument cluster screen performance or improper display operation. Driver Information Display or Virtual Cockpit Unit (VCU) labor codes only can be used for the applicable systems and are restricted by program. (Fig. 1, Equinox with VCU system)

Labor Codes for Instrument Cluster Screens
CCND Labor Operation 0540739 (Driver Information Display (Cluster Screen or Combined) – Customer Concern Not Duplicated) – Labor code 0540739 applies to vehicles equipped with the VCU Infotainment System (RPO IVA, IVE, IVD) that has conditions that affect the Driver Information Display (DID) screens (instrument cluster screen or combined screen). (Fig. 2)

CCND Labor Operation 0540759 (Instrument Panel Cluster (IPC) – Customer Concern Not Duplicated) – Labor code 0540759 should be used for Instrument Panel Cluster concerns on vehicles that are not equipped with RPO IVA, IVE or IVD (center cluster screen). (Fig. 3)

These program-specific labor codes should be used when diagnosing concerns with screen or display operation. Warnings or incorrect information relayed from other systems like fuel, propulsion, etc., require using the more appropriate CCND labor code related to the specific system concern.
Speaker, Amplifier, Microphone-Related Labor Codes
CCND Labor Operation 0541509 – The description for audio CCND labor code 0541509 has been changed to Speaker, Amplifier, Microphone Audio Issue CCND to help ensure the code is used for audio system speaker, amplifier and microphone-related conditions only. (Fig. 4)

Occasionally, the code has been used for a variety of audio issues or concerns that would be more accurately represented by other CCND labor codes. For example, if there is a loss of audio when other system issues also exist, such as a display screen that is frozen/blank or if the loss of audio occurs only during use of certain apps, features, switches, radio sources/channels, calls/connections (i.e. Bluetooth), etc., it is more appropriate to use the CCND labor code related to the system concern.
