Solved! Autel IM608 + XP400 Benz Chip Communication Failed


It is always the same when I am using Autel MaxiIM IM608 + XP400 Key Programmer to make automatic detection for a Mercedes Benz key.

It says “Chip communication failed. Please check whether the chip is placed correctly or in good contact”

What is the problem? Please help me!

The solution from AUTELDIAG engineer:

The reason why the Mercedes-Benz key failed is that IR key can’t be detected with automatic detection. Please try “IR (Mercedes)” function scrolling down at the menu.

Problem was solved, Autel IM608 scan tool and XP400 can detect Mercedes key successfully now!

Thanks to Auteldiag engineer!
