GHG17 DD Medium Duty Operators Manual Performing a Parked Regeneration - GHG17 Performing a Parked Regeneration - GHG17 Perform a Parked Regeneration as follows: WARNING: ENGINE EXHAUST To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic. WARNING: HOT EXHAUST During parked regeneration the exhaust gases will be extremely HOT and could cause a fire if directed at combustible materials. The vehicle must be parked outside. NOTE: Under factory default settings, when the Diesel Particulate Filter (DPF) Regeneration Lamp is not illuminated, the regeneration request switch is disabled. NOTE:
The driver MUST stay with the vehicle throughout the regeneration process. NOTE: Not all vehicles may be equipped with a Regeneration Request Switch due to application or user specification. NOTE: The procedure will take approximately 30 to 45 minutes (depending on engine type and the amount of soot accumulated in the DPF). When the parked regeneration request is accepted, the Diesel Particulate Filter (DPF) Regeneration lamp will turn ON one time for one second and then turn off for the remainder of the parked regeneration.
The High Exhaust System Temperature (HEST) lamp will flash for one second every ten seconds and eventually become solid when the tailpipe temperature is above 525°C (977°F). The engine speed may vary during parked regeneration (depending on engine displacement, exhaust temperature and the amount of soot accumulated in the DPF). The regeneration is complete when the engine returns to idle and the DPF lamp remains OFF. The HEST lamp will remain ON, but the vehicle may be driven.
