Parked Exhaust Filter Cleaning is an automated process which allows the system to clean the exhaust filter when required. During the process the engine speed will be controlled by the system and the machine must remain parked to complete the procedure. Time required for the Parked Exhaust Filter Cleaning process is dependent upon the level of exhaust filter restriction, ambient temperatures and current exhaust gas temperature. Display will provide estimated time to completion.

Follow instructions shown on display to complete the Parked Exhaust Filter Cleaning process.

NOTE: Parked Exhaust Filter Cleaning may exceed 40 minutes.

Once process is started a status screen appears.

There are two steps in the Parked Filter Cleaning process (Figure A), preparation and cleaning. During the preparation step, the Exhaust Filter System will control engine speed to increase exhaust temperature. During the cleaning step, diesel particulates or soot is cleaned from the Exhaust Filter System.

System informs (Figure B) operator when Parked Filter Cleaning is complete. If you are not returning the machine to service immediately after procedure, allow engine time to return to normal operating temperature before stopping engine.

NOTE: At any time during the parked procedure, the process can be canceled by advancing the throttle, engaging transmission, or stopping engine.

System defaults to AUTO mode when parked exhaust filter cleaning is complete. Always verify that AUTO mode is selected, unless in conditions where it may be unsafe. See When to Disable Exhaust Cleaning System in this section.
