PARKED REGENERATION

Regeneration is the oxidation of soot in the Aftertreatment Device (ATD). This process happens
during the normal operation cycle of the vehicle; it can occur both passively and actively. If the
ATD is not capable of completing a successful regeneration due to duty cycle constraints or other
restrictions, a parked regeneration may need to occur.
5.19.1 OPERATION
To initiate a parked regeneration, the following must occur:
□ Cycle the park brake OFF to ON – once an ignition cycle
□ Cycle the clutch pedal (if configured) – once an ignition cycle
□ Park Brake must be ON and the clutch must be released
□ Engine should be on the idle governor (can not be in Fast Idle or PTO Mode)
□ The engine should be fully warmed up and operating on thermostat temperature (>60°C)
□ For J1939 transmissions, the transmission must be in neutral (confirmed by the J1939 data
link – current gear and selected gear is 0)
□ Vehicle speed must be 0 mph
□ Hold the Regen Switch to the ON position for five seconds and release
When the request is accepted, the DPF Regeneration Lamp will turn on for one second and then
go off for the rest of the parked regeneration and the engine will increase. Once the stationary
regen is completed successfully, the DPF Regeneration Lamp will remain off and the engine
will return to base idle.
If any of the above requirements are removed, the engine will return to idle.
To cancel the manual regeneration, the driver can toggle the Regen Switch to ON for 5 seconds.
The DPF Regeneration Lamp will turn on for one second to show acceptance of the cancellation
request and then return to the appropriate state as defined by the current level of soot in the engine.
5.19.2 DPF PARKED (STATIONARY) REGENERATION ONLY
NOTE:
This is for hazardous applications only.
The MCM should be configured to not allow automatically triggered over-the-road regenerations
(DPF Manual Regen Only Enable = Enabled).
The appropriate options, based on the MCM, are listed in Table 5-63.
