A failure in the flash job routine may cause the Program Block error while attempting to reprogram CPC3, MCM21T, or the ACM21T modules. See steps below:
- Check the Nexiq USB-Link 2 device driver version.
- Go to Control Panel Programs (for Windows 10, right-click Windows button, and left click Apps & Features).
- Click on Nexiq USB-Link 2.
- If running previous version (e.g. v126.96.36.199, v188.8.131.52, or v184.108.40.206), visit Nexiq.com >Download A Driver.
- Download and install version 220.127.116.11 or later.
- Restart Windows and try reprogramming again.
If updating the driver is not an immediate option (e.g. No Administrator Rights), use temporary work around:
- Disconnect the Nexiq USB-Link 2 cables from the vehicle 9-pin and from the computer USB port.
- Reconnect both connections and try reprogramming again.
- When possible, have your local IT Administrator install the updated Nexiq drivers.
This message indicates a failure to connect to application server. This may be due to one of the following conditions:
- TCP Port 48481 is closed/blocked
- Customer's WiFi settings is blocking required access
- DTNA Server Outage
- Customer has no internet or network access
- Verify internet connection. Try connecting to Google.com or Yahoo.com. I connection fails, contact your local IT Admin or Network admin or internet provider to resolve.
- Verify access to TCP Port 48481 (required). To test, copy-paste the WSDL link below into web browser and hit enter:
If the page displays general text, the required port is open. If the page displays error (e.g. Cannot Open Page), this may indicate that TCP Port 48481 is closed. If closed, contact your locate Network/IT Admin to resolve.
If a Proxy login is required to access the internet, please first resolve proxy login requirements and then connect to server with DiagnosticLink to verifiy operation. Also check security settings such as a Firewall or Anti-virus to see if it's blocking access to webserver. It's usually quite easy to temporarily disable anti-virus, and retest DL8 server connection.
When the error 'User ID is not Authorized' is encountered, it's generally associated with a particular VIN in which the SSO ID (most commonly P70/public ID) does not have access to the VIN server data.
- From the DL8 workstation displaying the error; try downloading a different engine serial number (without the VIN). If using a public (P70) SSO ID, request to the have the Programming Event reset by emailing DTNASSD@daimler.com a request to reset event due to a programming error. Include a screen shot of the error and the user ID.
- If the secondary engine serial number downloads successfully, contact the Dealer Help Desk to check the user ID and VIN.
