Three diagnostic methods are available:
• Intelligent Diagnostics:
The system will automatically guide you directly to the x and
help you eliminate guesswork, without step-by-step manual
menu selection.
• Local Diagnostics:
You need to manually select the menu-driven command.
• Remote Diagnostics:
This helps repair shops or mechanics to diagnose a remote
vehicle, and launch instant messages, allowing for improved
e󰀩ciency and faster repairs.
For new users, the Local Diagnostics is recommended as follows:
Select vehicle model
Tap "Local Diagnose"
Select software version
