13.2 About SmartLink Diag.
1. What’s network conditions is required for SmartLink Diag.? The remote SmartLink Diag. operation requires a network broadband of 100 MB or above.
2. What does the word “Delay” displayed on the SmartLink C screen mean? The Delay (network delay) indicates the state of the network communication, which can be regarded as a reference since different vehicles require different delays. Different colors represent different delay status. There are three states of network delay: Green: Indicates a shorter network delay. In this case, it has a higher success rate of remote communication. Yellow: Indicates a medium network delay. In this case, it has a medium success rate of remote communication. Red: Indicates a longer network delay. In this case, it has a lower success rate of remote communication and remote ECU reprogramming operations are not suggested.
3. My network delay is so long. Please check the following possible reasons:

1. The greater distance between the SmartLink B2.0/SmartLink B and SmartLink C V2.0 dongle causes
   a longer network delay. 2. There are too many network communication nodes that the data communication passes by, which
   may cause a longer network delay. 3. Check if the network is poor and data communication speed is slow.
   4. Some systems of some old vehicles cannot be tested The SmartLink C V2.0 dongle supports CAN2.0/CANFD/DoIP communication protocols, but some old vehicle uses K-Line communication protocol.
