Description of Change

ADEPT™ technology is a set of electronic features including SmartTorque2 and SmartCoast™, Predictive Gear Shifting, Predictive
Engine Braking, On-ramp Boost, Predictive Road Speed Governor, Dynamic Power and Hill Roll Out.

Predictive Gear Shifting, Predictive Engine Braking, and On-ramp Boost require an ADEPT™ Technology ECM Calibration Code.
See ADEPT column in Table 6 below.

Dynamic Power and Hill Roll Out are available only for X15 CM2450 X124B engine ratings that have ECM calibration codes starting
with 'KW' located in Table 6 in the ADEPT™ Technology ECM Calibration Code column.

SmartTorque2 senses the selected gear, road grade, and overall engine load. As these conditions vary, SmartTorque2 determines
the exact amount of torque required to maintain road speed and eliminate unnecessary downshifts.

SmartCoast™ has been added to improve the efficiency of coasting events. SmartCoast™ will disengage the driveline on moderate
downhill grades or when the operator lifts off the accelerator pedal, allowing the engine to return to idle.

Predictive Gear Shifting improves vehicle speed tracking performance during cruise control. The feature will utilize vehicle
characteristics and road grade profile information to determine the proper transmission gear when the engine is power limited on
hills.

Predictive Engine Braking aims to enhance the vehicle speed limiting capability of existing engine brake features based on the
upcoming road grade. The features to which this predictive functionality can apply are Cruise Control and Engine Brake Interaction
or Maximum Vehicle Speed Control.

On-ramp Boost is a performance feature that improves vehicle acceleration on an on-ramp leading to an interstate which increases
the merging speeds and assists in an easier merging maneuver. It allows the vehicle to operate in a fuel-efficient mode during
regular operation and allows better performance during critical situations.

Predictive Road Speed Governor improves efficiency of the vehicle by adjusting the Road Speed Governor within programmable
offsets based on current and upcoming road grade.

Dynamic Power aims to improve overall engine efficiency by limiting use of excessive torque when it is not required. Utilizing similar
references as SmartTorque2, Dynamic Power modulates available engine torque to reflect current vehicle operation &
environmental influence.

Hill Roll Out is a powertrain efficiency feature which allows early disengagement of engine brakes and allows a temporary vehicle
speed increase when the vehicle is approaching end of downhill moderate grades. This predictive functionality allows the vehicle to
harness momentum to traverse upcoming terrain. Hill Roll Out can request SmartCoast™ events to increase efficiency based on the
operating mode enabled for SmartCoast™. Reference SmartCoast™ section for more information on SmartCoast™ operation.

Note : Predictive Gear Shifting, Predictive Engine Braking, On-ramp Boost, Dynamic Power, Predictive Road Speed
Governor, and Hill Roll Out require either a Connectivity Module, Cummins® Route Parameter Manager (RPM) or an
OEM Predictive Cruise Control module to get look-ahead road information.

5504583. Refer to Procedure 019-032 (/qs3/pubsys2/xml/en/procedures/105/105-019-032.html) in Section 19.

Note : Dynamic Power and Hill Roll Out are available only for X15 CM2450 X124B engine ratings that have ECM
calibration codes starting with 'KW' located in Table 6 in the ADEPT™ Technology ECM Calibration Code column.

5. Clear resulting fault codes

¢ Depending on the download sequence an inactive fault code 5297 can be logged in the ECM after the upgrade as a result of
transmission and ECM communication loss during calibration event.

6. Verify ADEPT™ features are turned on in the ECM. Under the Features and Parameters section in INSITE™ electronic service
tool:

For Ultrashift® or Advantage® Transmissions:

Adjust “SmartCoast’ to “Enabled” if set to “Disabled” (May be located in the Cruise Control section or as a separate featured
called SmartCoast). The Advantage or Ultrashift transmissions only support Smart Coast in cruise control.

o The Smart Coast features may not be restored after a calibration has taken place using a vehicle electronics
programming station (VEPS) machine. Use INSITE™ electronic service tool to connect to the ECM and follow the
instructions in Step 6 to confirm that the parameter Smart Coast is set to Enabled.

Adjust “Load Based Torque Control” to “Smart Torque 2” if set to “Base”.
Adjust “Road Speed Governor Type” from “Traditional” to “Predictive”. If Predictive Road Speed Governor is unavailable in the
calibration, “Road Speed Governor Type’ will be Read Only.

For Endurant™ Transmissions:

Adjust “SmartCoast’ to “Enabled” if set to “Disabled”. The Endurant transmission supports Smart Coast in accelerator control,
cruise control, or cruise and accelerator control.
° If available, set the “Operating Mode” to the desired option (select “Both” for maximum coasting opportunity).
o If available, set the “Adjustment Factor” to the desired option (Feature defaulted to “Maximum Economy” for maximum
coasting opportunity on ‘EX’ ratings only. Adjust to desired performance level if the default selection is not suitable).
o The Smart Coast features may not be restored after a calibration has taken place using a vehicle electronics
programming station (VEPS) machine. Use INSITE™ electronic service tool to connect to the ECM and follow the
instructions in Step 6 to confirm that the parameter Smart Coast is set to Enabled.

For CM2450 (ECM calibration code starting with 'KW' located in Table 6 in the Existing ECM Calibration Code column) and
CM2350 ECMs, Adjust “Load Based Torque Control” to “Smart Torque 2” if set to “Base”.
o For CM2450 ECMs with ECM calibration code starting with 'KW' located in Table 6 in the ADEPT™ Technology ECM
Calibration Code column, adjust "Load Based Torque Control" to "Dynamic Power" if set to "Base".
o Feature defaulted to “Maximum Economy”, adjust “Fuel Economy Adjustment Factor” to desired performance level if the
default selection is not suitable.
Adjust “Predictive Gear Shifting” to “Enabled” if set to “Disabled”.
Adjust “Predictive Engine Braking” to “Enabled” if it is set to “Disabled”.
Adjust “On-ramp Boost’ to “Enabled? if it is set to “Disabled”.
Adjust “Road Speed Governor Type” from “Traditional” to “Predictive”. If Predictive Road Speed Governor is unavailable in the
calibration, “Road Speed Governor Type’ will be Read Only.
Adjust “Hill Roll Out Enable” to “Enabled? if it is set to “Disabled”.

Note : Predictive Gear Shifting, Predictive Engine Braking, On-ramp Boost, Dynamic Power, Predictive Road Speed
Governor, and Hill Roll Out features are only applicable if the vehicle has a Connectivity Module, Cummins® Route
Parameter Manager or OEM predictive cruise control system.

7. Set upper and lower cruise control droops to customer desired settings.

¢ Default settings are 3 miles per hour (mph) upper and 6 mph lower.
¢ The Cruise Control Lower Droop controls the range of cruise control based SmartCoast™. SmartCoast™ will not function with

a0 mph Cruise Control Lower Droop. Maximum fuel economy is achieved using 6 mph, and a minimum of 3 mph is
recommended.

8. Set Road Speed Control maximum speed to customer desired settings.

¢ The RSG Maximum Vehicle Speed sets the maximum coasting speed for Accelerator Control operating mode. A minimum of 3
mph greater than maximum Accelerator Vehicle Speed is recommended.

¢ Ifthe Maximum Vehicle Speed Control feature is used, the start braking speed will also set the maximum coasting speed. A
start braking speed that is a minimum of 3 mph greater than Maximum Accelerator Speed is recommended.

9. Adjust the Predictive Road Speed Governor Maximum Positive and Maximum Negative Offsets to customer desired settings.

¢ Input both parameters as positive values.
« “Road Speed Governor Type” must be set to “Predictive” for the maximum offsets to be visible.

10. Adjust the Hill Roll Out Maximum Offset to customer desired settings.

« The recommended setting is a value that when added with Cruise Control Lower Droop, the resulting value is greater than 6
miles per hour (mph). If Maximum Vehicle Speed Control is enabled, the Hill Roll Out Maximum Offset will not exceed the
Maximum Vehicle Speed Control Start Maximum Engine Braking Speed. Hill Roll Out Maximum Offset will be applied above the
minimum of Maximum Vehicle Speed Control Start Minimum Engine Braking speed and Road Speed Governor Maximum
Vehicle Speed when Hill Roll Out disengages the engine brake early.

11. If any fault codes or symptoms remain, reference the standard troubleshooting procedures. If Fault Code 5297 is active, review
the transmission type and features in Table 5 above to determine what was incorrectly enabled.
