Fault Codes / DTCs

This Technical Service Bulletin does not list specific Diagnostic Trouble Codes (DTCs). Instead, it broadly addresses general infotainment software issues and aims for stability improvements and bug fixes. The focus is on updating the AV Control Unit software rather than diagnosing specific fault codes.

What the Service Bulletin Says

Technical Service Bulletin NTB23-018C details the process for updating the AV Control Unit software. The update is performed using a special USB drive, part number J-52727-1 (NI-52727-1), which technicians download the necessary software onto via the ASIST system. The bulletin outlines several different software check and installation procedures (SW Check 1 through SW Check 6, Install 1 through Install 5) depending on the vehicle model and current software version.

The update process involves connecting a battery maintainer, setting the parking brake, turning on hazard lights, and following specific steps to access the service menu and initiate the software installation. It emphasizes the importance of using the correct USB media port and not interrupting the process. After the update, the AV Control Unit may require reinitialization, and owners will need to re-pair their Bluetooth devices. Additionally, the update introduces a new feature called "SXM Smart Favorites" to the infotainment system.
