If the Launch DBscar VII or Smartlink VCI appears “Diagnostic connector connection is abnormal” problem, how to solve it? Check the solution below.
The solution:
First, please select reconnect 3 seconds after the connector restarts successfully (a beeping sound).
If it’s legitimately losing connection to the VCI, try to fix the VCI Firmware Fix in settings.
For Launch X431 V+ 5.0, PRO3S+ V5.0, CRP919E BT, PRO3 APEX, etc with DBScar VII connectors:
Open X431 APP, select User Info>> Firmware Fix>> Press Firmware Fix>> Scan Bluetooth connector
Select User Info>> Fix connector firmware/system>> Fix Connector Firmware or Fix Connector System
If SmartLink VCI turns black screen, do a firmware fix.
