Read full descriptionHide full description
The Lippert Diagnostics app allows users to connect to a device and read the Diagnostic Trouble Codes (DTCs) from the device. DTCs will enable users to troubleshoot why a device does not function correctly. Users can scan QR codes to connect to a device. The diagnostic app will then show a user the number of active trouble codes on that device and inactive trouble codes.
