Programming Cummins Engine with OnCommand® Link
Important points to note about updating calibrations on Cummins engines
•The calibration update process for Cummins engines is divided into four phases. Each phase is
triggered when the OnCommand® Link is connected to the Internet. For the first three phases,
the OnCommand Link™ only needs to be connected to the Internet for a period of 5-10 minutes.
For the ‘Update Calibration’ phase, the OnCommand® Link device should stay connected to the
Internet until the user sees the message ‘Engine calibration up-to date’ on the application page.
•The simplest approach for obtaining updates to Cummins engines for the first time is to leave
the OnCommand® Link device on a vehicle for at-least 10 hours.
•If your OnCommand® Link has already completed a calibration update once on a given vehicle,
from next time onwards you will not be required to wait for 10 hours (as registration phases is a
one- time process as far as OnCommand® Link stays on the same vehicle) to perform a
calibration update. You would just need to occasionally connect OnCommand® Link to Internet
source with key ON/Engine running and it will automatically start with ‘Preparing update’phase
when an update is available for your vehicle.
•If the OnCommand® Link device is connected to another vehicle, the 10 hours process will start
all over again.
•Calibration updates for Cummins engines are prepared based on data collected by the
OnCommand® Link from engine modules. This data is transmitted to the backend servers
whenever the OnCommand® Link is connected to the Internet. The data received from your
engine module is analyzed and used to determine if your engine module needs a calibration
update.
•If your engine needs a calibration update, a unique calibration file is prepared for your engine
based on the data received from the OnCommand® Link. The OnCommand® Link device
application page will indicate when a calibration update is available.
•Currently, Over-The-Air calibration updates are supported on 2017 or later Cummins engines
only. The below message is displayed when OnCommand® Link is connected to an incompatible
Cummins engine (2016 or earlier Cummins engine).

Page 14 of 31
Detailed process to update/check calibrations on your Cummins-powered
vehicle
1. Device Registration phase (Triggered when the OnCommand® Link device is connected to the
Internet the first time on a new vehicle):
a. To update Cummins engines, the OnCommand® Link must first be registered with a
particular Cummins engine (by engine serial number). This process is initiated when
the OnCommand® Link is first connected to the Internet. Registration takes at-least
4 hours to complete. Once the OnCommand® Link application indicates that
egistration process is initiated, it does not need to remain connected to internet
source for 4 hours to complete this process. The registration phase completes on its
own in the background.
Figure 11. Device Registration phase
b. As long as the Link device remains on the same vehicle, the registration process is
performed only once for a given vehicle. The registration process must be repeated
each time an OnCommand® Link is connected to a different vehicle. During this
process, vehicle can be turned off.
2. Checking for Update phase (Triggered each time the OnCommand® Link connects to the
Internet after the “Device Registration phase” and key is ON/Engine Running):
a. The OnCommand® Link gathers engine data from your vehicle and sends it to the
backend for processing. The backend system processes this information to
determine if your engine needs a calibration update. This process takes at least 5
hours to complete. Once the OnCommand® Link application indicates that checking
for update process is initiated, it does not need to remain connected to internet
source for 5 hours to complete this process. The checking for updates phase
completes on its own in the background.

Page 15 of 31
Figure 12. Checking for update phase
3. Preparing Update phase (Triggered when the OnCommand® Link device connects to the
Internet—after the “Checking for Update phase”):
a. Connect your personal device to the OnCommand® Link and open the application
page.
b. If your application displays ‘Engine calibration up-to date’, wait for 5 minutes. If you
still see ‘Engine Calibration up-to date’, your vehicle calibration is up-to date.
Figure 13. Preparing update phase: Engine calibration up-to date
c. If your vehicle needs a calibration update, the application will start preparing your
engine for the update. Preparing the engine takes about 30 minutes. The engine can
be prepared while the vehicle is in motion or in a KEY-ON, ENGINE-OFF state. If the
key is turned OFF, the engine preparation pauses and continues again after the key
is turned ON.

Page 16 of 31
Figure 14. Preparing Update phase: Update available and preparation in progress
4. Update Calibration phase (Triggered when the OnCommand® Link connects to Internet—
after the “Preparing Update phase”):
a. Connect your personal device to the OnCommand® Link and open the OTA
application.
b. This phase is only required if your vehicle needs a calibration update.
c. Click on the ‘Update Calibration’ button to initiate the calibration update process.
Please read the warning message and click Accept and Update Calibration to
confirm that all mandatory conditions are satisfied before initiating a calibration
update.
This process takes 5 minutes to complete.
Note: If fault codes are noticed with flashing lights on the dash after calibration update, please perform
a key cycle (KEY OFF followed by KEY ON) and confirm that no further faults are seen on the dash. If
faults are still seen on the dash, please contact Technical Support

Figure 16. Update Calibration phase: Calibration update in progress
Rollback Calibration on Cummins Engine
In cases where Cummins engine has been updated with an invalid calibration and needs to be reverted
back to an earlier calibration version, backend systems may trigger a rollback command. If you notice a
‘Rollback Calibration’ button on application page, this means backend systems have triggered a
calibration rollback for your engine. Click Rollback Calibration to initiate calibration rollback process.
Please read the warning message and click Accept and Update Calibration to confirm that all mandatory
conditions are satisfied before initiating a calibration rollback.
This process takes 5 minutes to complete.
