Description of Change
ADEPT™ technology is a set of electronic features including SmartTorque2 and
SmartCoast™, and Predictive Gear Shifting.
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 is only available when used in conjunction with Cummins® Route
Parameter Manager or an original equipment manufacturer (OEM) predictive cruise
control system and will utilize vehicle characteristics and road grade profile information to
determine the proper transmission gear when the engine is power limited on hills.

Service Instructions
Electronic Tools Required:
• INSITE™ Pro electronic service tool for engine calibration update
• ServiceRanger™4 for transmission software update (if required)
1. Check engine, transmission, and adaptive cruise control system compatibility. See
Product Affected Table, Table 1, Table 2, and Table 3 for applicability.
2. Review ADEPT™ technology documentation on cumminsengines.com and
communicate modification charge to customer.
• The customer will incur a fleet count charge as well as the stated modification
charge.
3. Verify that transmission software meets minimum software requirement. See Table 4.

• If necessary, update the transmission using the Eaton™ ServiceRanger™4 service
tool.
• If minimum transmission software requirement is not met, ADEPT™ features will not
function properly and fault codes can be triggered.
◦ If a feature is enabled that the transmission does not support, fault code 5297
will come active as a result.
4. Update the engine calibration to ADEPT™ technology calibration using selection
matrix in Table 5 below. See the ISX15 CM2350 X101 Service Manual, Bulletin 4310641.
Refer to Procedure 019-032 (/qs3/pubsys2/xml/en/procedures/105/105-019-032.html) in
section 19. See the X15 CM2350 X114B - Efficiency Series Service Manual, Bulletin
5411181. Refer to Procedure 019-032 (/qs3/pubsys2/xml/en/procedures/105/105-019032.html) in section 19.

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:
• Adjust “SmartCoast” to “Enabled” if it is set to “Disabled” ((May be located in the
Cruise Control section, or as a separate feature called SmartCoast)
◦ If available, set the “Operating Mode” to the desired option (select “Both” for
maximum coasting opportunity)
• Adjust “Load Based Torque Control” to “Smart Torque 2” if it is set to “Base”
• Adjust “Predictive Gear Shifting” to “Enabled” if it is set to “Disabled”
◦ Note: 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.
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 a 0 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.
• If the 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. If any fault codes or symptoms remain, reference the standard troubleshooting
procedures.
