Error Message: Detect Protocol Failed

Problem

The Detect Protocol Failed error is caused by noise in the vehicle's communications or because an MPVI2/2+ needs to be resynced.

Resolution

1. If you have an MPVI2/2+,
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.
