Updated purpose of the bulletin to call out 1 repair per Vehicle Identification Number (VIN). This bulletin informs dealers that Harley-Davidson has specific areas of interest while troubleshooting on Revolution® Max platform vehicle built before July 1, 2023 for issues on starting or Diagnostic Trouble Codes (DTCs). These areas of interest should be used in conjunction with the Service Manual and Electric Diagnostic Manual while troubleshooting.
