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. The GM
Diagnostic Worksheets are available to you at no cost. GM Service Bulletin 58-01-01 has information on how to order this diagnostic worksheet.
