For manual transmissions, fully depress the
clutch pedal, put the transmission in neutral, then
release the pedal.
If the vehicle has a two-pedal automated trans-
mission, shift it into gear, then back to neutral.
IMPORTANT: The driver must remain with the
vehicle during the entire regen cycle.
3. Press and hold the regen switch for 4 seconds.
The engine will increase rpm and initiate the
regen process.
4. After the parked regen has run for 20 to 40 min-
utes, the regen cycle is completed. The engine
idle speed will drop to normal, and the vehicle
may be driven normally. The HEST lamp may be
illuminated, but will go out when the vehicle
speed exceeds 5 mph (8 km/h), or the system
has cooled to normal operating temperature.
5. To stop a parked regen at any time during the
process, engage the clutch, brake, or throttle
pedal, or turn off the engine.
Shorting Plug
NOTE: The DPF lamp must be illuminated be-
fore the shorting plug will initiate a parked
regen. See Fig. 9.1.
The shorting plug is used to initiate a parked regen
of the ATD. The shorting plug is located under the
dash, next to the steering column. Mounting locations
vary. See Fig. 9.6.
To initiate a parked regeneration, perform the follow-
