5.2.2 Manual Diagnosis

If the tool can not obtain the VIN information, you can also perform vehicle
diagnosis manually. In this mode, you need to execute the menu-driven
command and then follow the on-screen instruction to proceed.
*Notes:
• Before diagnosing, please make sure the diagnostic program corresponding to
certain vehicle model has been installed on your tool.
• For vehicles manufactured by different vendors, it is possible that it has different
diagnostic menus. For details, please follow the instructions on the screen to
proceed.
Refer to the flowchart illustrated as below to diagnose a vehicle manually:
