12.2 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 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.
3. Why is the network connection so poor?
If the displayed network is poor, there may be too many people using the network in the LAN and some users are
downloading. It is recommended to use a stable network for remote SmartLink diagnosis.
4. Why does the sign
appear on the upper right corner of the SmartLink C screen?
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.
5. Some systems of some old vehicles cannot be tested
The SmartLink C device supports CANBUS and DoIP communication protocols, but some old vehicle uses K-Line
communication protocol.
6. Is it necessary to re-ignite the car after the diagnostic system starts working?
For the sake of some vehicle's conditions, the re-ignition will provide you a more detailed analysis after OBD
diagnosis.
7. Can I charge the SmartLink C device through an external DC power supply?
No. The SmartLink C device obtains power only through a vehicle’s OBD diagnostic socket. Getting power through an
external DC power supply could result in system malfunction.
8. How to update SmartLink C system?
After the SmartLink C device is powered on and connected to the network, a message “Whether to upgrade now?" will
