Diagnostic Work Sheets



Diagnostic Work Sheets
The GM Diagnostic Worksheet has been designed to improve communications between the service customer and the technician. The diagnostic worksheet can provide the technician with more information than the conventional repair order, since it is filled out by the service customer. Dealers in the US may contact Dealer Support Materials at 1-800-235-8521 and request Form Number DWS-01 to obtain these worksheets at no cost. Dealers may also access the DWD Store in Dealerworld and search for form DWS-01 or select Service Forms under Other Links and then select Diagnostic Worksheet (under Bulletin Information on use of Diagnostic Worksheet). Please limit your requests to a reasonable quantity.
