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 Obdii.shop 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!
