Stationary Regeneration Procedure
Take the following steps when performing a stationary regeneration. Refer to the
DPF regen flowcharts (page 64) for a further understanding of this procedure.
1. Move to a safe location that is well-ventilated.
2. Set the acceleration of the engine to its lowest position and run the engine at
idle speed. Ensure the engine’s coolant temperature is above 140° F (60° C).
3. Engage the parking brake.
4. When the DPF regen request switch is pressed:
Operator Initiated: Press and hold for 10 seconds, release, then hold for
an additional three seconds and the stationary regen starts. The engine
speed will gradually increase to a high idle speed.
E-ECU Initiated: Press and hold for three seconds and the stationary
regen starts. The engine speed will gradually increase to a high idle
speed.
5. The stationary regen procedure takes approximately 25 to 30 minutes to per-
form.
6. When the above time has passed, the engine speed gradually decreases to the
low idle speed and the DPF regen acknowledgement lamp and the EGT lamp
turn off. Stationary regen is completed.
Note: When stationary regen starts, the DPF regen-required lamp turns off, the
DPF acknowledge lamp briefly appears and the EGT lamp illuminates.
Stationary Regeneration Abort Procedure
To abort a stationary regen, perform any one of the following steps.
1. Set the DPF switch to its inhibit/cancel state.
2. Command the accelerator to a position above its lowest position.
3. Turn the manual parking brake switch to its OFF position.
4. Turn the keyswitch to the OFF position.
Note: Depending upon the PM levels and which switch was used to abort the sta-
tionary regen, the E-ECU will either go back to normal operation or stationary
regen standby mode.
Note: Interrupting a reset or stationary regen will require a full reset or sta-
tionary regen process in the future. The E-ECU does not command partial reset
or stationary regens.
