Checking DTCs Manually (HD)


With the Centurion diagnostics software you have the ability to check and clear diagnostic trouble codes on Harley Davidsons. If for some reason you are unable to, you can check and clear diagnostic trouble codes through the bike itsself. To do so follow the steps below:

Pre 2014 Harley Davidson motorcycles:
  • Press and hold in the odometer button.
  • While holding the odometer button in, turn the bikes ignition on.
  • When the bike turns on you see "diag" appear on your odometer.
