The latest diagnostic assistance from the professionals at the GM Technical Assistance Center is now available in the September GM Technical Assistance Center (TAC) Newsletter. It covers a number of concerns that TAC is addressing every day on cases with dealerships. Each month, we publish the newsletter as a PDF, making it easy to view online or print for reference.
With the tips provided by TAC, dealerships get additional information on the latest diagnostics and repairs to help get vehicles back to customers quickly. Each newsletter provides details about recent Bulletins and Preliminary Information (PI) that have been released along with tips on other known concerns, diagnostic testing, parts information and availability, and new product news.
The newsletter is organized in several categories, including General; Engine; Electrical, Chassis and Trim; Transmission and Drivetrain; Infotainment and OnStar; Hybrid and EV; DCM and TAC Cases and other topics.

If a new case is started with no diagnostic information, but the previous case number is added and a request to call in is made, you can call in with the new case number. Look for more information from TAC soon.
THIS INFORMATION IS INCORRECT:
“Closing TAC Cases; If the case you are working with has been closed, please call TAC and, most times, the case can be reopened to get all the information on the same case.”
PHONE SYSTEM WILL NOT LET YOU IN WITHOUT A VALID OPEN CASE NUMBER.
