Diagnostic Trouble Code Priorities

IMPORTANT: These diagnostic trouble codes are listed for reference only. Go to the diagnostic group of the problem system for specific diagnostic information.

Each diagnostic trouble code (DTC) has a priority. The priority of the DTC is indicated in the way the DTC is displayed to the operator:

  • Stop - indicates a problem that requires the machine be stopped, the engine turned OFF immediately and the problem corrected. DTC is shown until the problem is resolved.
  • Service Alert - indicates a problem should be checked immediately.
  • Information - DTC is stored, but is not indicated to operator.
