A:Yes, you can.

A:Yes, Support commercial vehicles, passenger vehicles, new energy and other models: Covering Cummins, Bosch, Weichai, Shangchai, Yuchai, Xichai, Chaochai, Yangchai, Quanchai and other engine diagnostic software, it supports trucks, buses, construction machinery, agricultural machinery, trailers, ships and other types of vehicle software.

A:Yes, can support WIFI, Bluetooth and other communication methods.

A:No. The SmartLink C dongle obtains power only through a vehicle's OBD diagnostic socket. Getting power through an external DC power supply could result in system malfunction.

A:For the sake of some vehicle's conditions, the re-ignition will provide you a more detailed analysis after OBD diagnosis.

A:The SmartLink C V2.0 dongle supports CANBUS and DoIP communication protocols, but some old vehicle uses K-Line communication protocol.

A:Some networks have firewall restriction which leads to a longer delay of connection. You are most likely to see this sign while your system is in connection with networks managed by communities or companies. It is recommended to use the networks directly installed by telecommunication operators where there is no firewall restriction.

A:If the displayed network is poor, there may be too many people using the network in the LAN (Local Area Network) at the same time and some users are downloading. It is recommended to use a stable network for remote SmartLink diagnosis.

A:The remote SmartLink operation requires a network broadband of 100 MB or above.

A:The Delay (network delay) indicates the quality of the current network. Different colors represent different delay status. There are three states of network delay:
Green: Indicates the network is normal. 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.
Yellow: Indicates the network is not stable. Please keep it stable.
Red: Indicates the network delay is serious and not suitable for remote diagnosis or the network is disconnected.
