Data is missing or incorrect
If information displayed in DTK appears to be missing, incomplete, or incorrect, the issue may involve the selected equipment, ECM communication, server data, or previously stored diagnostic information.
Expected result
DTK displays the correct information available for the connected equipment.
Supported parameters, faults, and diagnostic functions are accessible.
Important notes / prerequisites
Examples include:
- Missing engine information.
- Incorrect equipment identification.
- Missing parameters or features.
- Unexpected fault information.
- Incomplete diagnostic session information.
Troubleshooting steps
Step 1: Verify equipment information
Review the equipment information entered during Intake.
Ensure the correct engine or equipment is selected.
Step 2: Verify ECM communication
Confirm that DTK is communicating with the expected ECM.
Some information is only available after communication with the appropriate control module has been established.
Step 3: Refresh the information
Return to the appropriate screen and reload the information.
If necessary, disconnect and reconnect to the equipment.
Step 4: Verify the source of the information
Determine whether the information is:
- Read directly from the ECM.
- Retrieved from a Cummins server.
- Loaded from a previously saved file or diagnostic session.
Information from different sources may not always be identical.
Step 5: Confirm feature availability
Not every engine program supports the same parameters, features, or diagnostic functions.
Verify that the requested information is supported for the connected equipment.
Step 6: Contact support
If information remains incorrect, capture screenshots and record the equipment details before contacting Cummins Support.
DTK Mobile differences
DTK Mobile and Windows may present information differently due to screen size and navigation.
Some information may be organized into separate screens or expandable sections on mobile devices.
Availability of individual functions may also differ between DTK Windows and Mobile.
