* During the remote diagnosis, please do not disconnect the vehicle and the network (the network broadband of 100Mb and above is recommended). In addition, a SmartLink C dongle can only receive one 

remote diagnosis operation at a time.

* When doing SmartLink diagnosis, the network delay will be displayed on the screen of the dongle. There are three states of network delay: green, yellow and red, which indicate that the network is normal, not 

stable and the delay is serious respectively. It is recommended that the diagnosis operation be performed when the network delay is green. Otherwise, the communication with the vehicle may fail or the 
incorrect system detection may occur.
