Manual Regeneration
Manual regeneration allows you to manually clear out the Diesel Particulate Filter (DPF). Completing a manual regeneration cycle will clear the soot mass in the filter, and lower exhaust back pressure to improve exhaust flow. The engine must be at operating temperature.
- Park the vehicle outdoors and keep people, other vehicles, and combustible materials away from it.
- Do not leave the vehicle unattended.
- Do not connect any shop exhaust hoses or vents to the tail pipe.
- STEP 1 – Access the Programming Menu.
- STEP 2 – Using the +RES or -SET, select mode 50 (MPH)
- STEP 3 – The speedometer will sweep to 140 then back down to 0. When the speedometer goes back to 0, you may then start the engine.
- STEP 4 – A few seconds after starting the truck, if all conditions are met, the regen will start. When regen is active, RPMs will increase up to 2500 RPM. If conditions are not met, the speedometer will sweep to 100 MPH for approximately 10 seconds and the Manual Regen will be canceled automatically.
- a. Vehicle must be to normal operating tempature for Manual Regen to initiate.
- STEP 5 – When the Manual Regen is complete or after the 10 seconds at 100 MPH, the speedometer will sweep to 140 MPH, indicating the function is complete.
CAUTION Exhaust temperatures may be greater than 300° C (572° F) during
service regeneration.
CAUTION Due to the elevated temperatures during this procedure, open the
hood and keep the front of the vehicle away from anything impeding the
radiator. DPF REGENERATION – If you own a newer diesel powered vehicle,
your vehicle is equipped with a Diesel Particulate Filter (DPF). This filter
is used in conjunction with a diesel oxidation catalyst. Together they work to
reduce the amount of soot and emissions emitted from the tailpipe. As soot
builds up in the DPF it will begin restricting flow. The soot that gathers is
automatically purged in one of two ways: Passive Regeneration & Active
Regeneration. Both methods occur automatically and require no action on your
part. During either of these regeneration methods, you may notice an increase
or change in the exhaust noise & increased Exhaust Gas Temperature (EGT).
Transmission Relearn
This vehicle is equipped with a transmission that will “learn” while you drive. Sometimes when these vehicles are programmed with an aggressive tune, the transmissions act differently. This feature forces the transmission to relearn and accommodate the new tune.
- STEP 1 – Access the Programming Menu.
- STEP 2 – Using the +RES or -SET, select mode 60 (MPH)
- STEP 3 – The speedometer will sweep to 140 MPH, indicating the function is complete.
Transmission Relearn driving instructions:
By selecting a Trans Relearn, you erase all shift points your transmission has
learned up to that point, so it is recommended that you follow the procedure
below.
- Start the relearn by making at least six sets of light throttle upshifts through all the gears, then make another six sets at 1/3, 1/2 and 3/4 throttle. Downshift the same way by starting at light throttle and working up to full throttle.
- Once the shifts are quick and smooth, press the ‘tow haul’ button and repeat the above step in ‘tow haul’ mode. Relearn normally takes up to two hours, but it can take up to 500 miles for the transmission to learn different upshifting and downshifting scenarios.
NOTE: After the relearn commands are sent there might be some clunks, bumps, and/or short flares, especially during the shift from third to fourth gear. This is normal.
Responsiveness Level Adjustment
When the vehicle is running and cruise control is turned off, the vehicle
throttle responsiveness can be adjusted. The responsiveness level is indicated
using the vehicle’s speedometer.
STEP 1 – Using the +RES or -SET, adjust to the desired value. The levels
changing will be shown on the speedometer, from 10 MPH to 50 MPH.
- Level 0 = Stock
- Level 1 = Reduced responsiveness (up to 15% less than stock)
- Level 2 = Increased responsiveness (up to 15% over stock)
- Level 3 = Increased responsiveness (up to 30% over stock)
- Level 4 = Increased responsiveness (up to 48% over stock)
- Level 5 = Increased responsiveness (up to 65% over stock)
STEP 2 – To recall the vehicle’s performance level, press the cancel cruise control button.
