Problem
The Detect Protocol Failed error is caused by noise in the vehicle's communications or because an MPVI2 needs to be resynced.
Resolution
| 1. | If you have an MPVI2, |
| a. | Make sure your computer is connected to the Internet. |
| b. | Open VCM Editor. |
| c. | In the Help menu, select Resync Interface. |
| 2. | If the issue persists after a successful resync (or you have a first-generation MPVI), we suggest using a bench harness to read and flash the vehicle. |
| 3. | If the problem still persists, start a support ticket and send us the following: |
| ￭ | A debug.dat file from your PC. |
| ￭ | A VCM Suite Infolog while connected to the vehicle. |
