Error Message: Detect Protocol Failed

Modified on Mon, 4 Dec, 2023 at 12:44 PM

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.
