I cannot sign in
If you cannot sign in to DTK, the issue may be related to your Cummins account, credentials, selected region, internet connectivity, or account access.
Expected result
The user successfully authenticates and gains access to the DTK application.
The application displays the functionality available through the user's assigned subscription.
Troubleshooting steps
Step 1: Verify internet connectivity
Ensure your device is connected to the internet.
An internet connection is required for initial authentication and may be required periodically to maintain access.
Step 2: Verify your account
- Confirm that you are using the correct account.
- Verify that your account is active.
- Ensure you have completed the required account registration process.
Step 3: Verify your selected region
Ensure the appropriate region is selected on the sign-in screen, where applicable.
An incorrect region may prevent successful authentication.
Step 4: Verify DTK access
Confirm that your account has been assigned the appropriate DTK subscription and permissions.
Having a Cummins account does not automatically provide access to all DTK functionality.
Step 5: Retry signing in
Close and reopen DTK, then attempt to sign in again.
If the issue continues, contact Cummins Support.
DTK Mobile differences
DTK Mobile uses the mobile device's authentication process and may open a browser-based sign-in experience.
Depending on the device and configuration, previously authenticated users may not need to enter their credentials every time they open the application.
