SmartLink C
Working Principle
The Smartlink Remote Diagnostics System is a newly developed powerful service
system dedicated to remote vehicle diagnosis and service. In this system,
Smartlink C user, as a Smartlink Service Subscriber, can submit remote repair
orders to vehicle repair companies (Smartlink B, the Smartlink Service
Provider) via Smartlink Service Platform (http://smartlink.x431.com). The
Smartlink C applies to vehicles that comply with CAN/Do IP/CAN FD/J2534
diagnostic protocol standard.
The Smartlink C system consists of the following two parts:
(9 SmartLink Service Platform — For binding the SmartLink C dongles and
posting the remote repair orders (Note: Orders can be submitted only after the
SmartLink C dongle is successfully bound).
0 Smartlink C Dongle — Connects with vehicle’s Data Link Connector (DLC) to
obtain vehicle information before submitting repair orders.
The working principle of the Smartlink C dongle is as follows:
Components & Controls
*Warning: The SmartLink C dongle obtains power through the vehicle’s DLC (Data Link Connector), and it is prohibited to connect to an external DC power supply. No responsibility can be assumed for any damage or loss caused as a result of not strictly following the above method.

-
-
The remote diagnosis can only be performed after the SmartLink C user has submitted the request, and this request has been accepted by the remote technician expert.
Operations
Operation steps:
- Turn off the vehicle ignition.
- Connect one end of the OBD 11 extension cable into the OBD-16 diagnostic connector of the Smartlink C dongle, and the other end into the vehicle’s DLC port.
-
For more information on DLC location. please refer to the Appendix.
- Plug one end of CAT-6 crossover cable into the LAN/WLAN port of Smartlink C the dongle, and the other end into the LAN port of the network modem.
-
The network broadband of 100MB and above is required for this operation.
-
After a successful network connection, the Smartlink C screen displays prompt information asking whether to enter the super remote diagnostic mode. Tap Yes, the system will automatically read the vehicle information and connect to the remote diagnosis server.
Each SmartLink C dongle can only accept one remote diagnostic operation at one time. -
Turn on the vehicle ignition.
After receiving the order, the SmartLink B master technician will accept the order and contact you via phone or E-mail address. Please make sure that you can be reached via the contact information provided by you.
-
After a successful connection between the Smartlink C and Smartlink Bis is established, the following message will be displayed on the Smartlink C screen.
-
-
Please do not interrupt the vehicle or network connection during a remote diagnostic process.
-
Please make sure that you are well connected with the internet when performing a remote online reprogramming process. 7. Unplug the crossover cable when a diagnostic session is completed.
Other Applications
-
Work as a VCI (Vehicle Communication Interface)
When as a VCI, the SmartLink C dongle needs to work in conjunction with the LAUNCH- the specific diagnostic tool, which is used to obtain vehicle data, and then send it to the tool for analysis via WiFi / Bluetooth / data cable.
-
Work as Local J2534 PassThru Device
Except that the SmartLink C acts as a VCI device and a SmartLink dongle, it also can be used as a local J2534 PassThru device, working together with the PC installed with the OEM diagnostic software to perform the J2534 reprogramming. In this case, the PC needs to install with the LAUNCH’s J2534 tool, which can be downloaded from www.x431.com.
-
Work as Remote J2534 PassThru Device
Additionally, the SmartLink C dongle can also be used as a remote J2534 PassThru device while performing remote ECU reprogramming functions.
Ensure that the remote J2534 reprogramming operation is performed after the SmartLink C dongle is connected to the vehicle’s DLC port and the Internet, and has been switched to the super remote diagnosis mode. For specific operations, please refer to other associated documents.
FAQ & Appendix
-
What’s the minimum requirement for network conditions?
The remote SmartLink operation requires network broadband of 100 MB or above. -
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 statuses. 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 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. -
Why is my network connection so poor?
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. -
Why is there a sign in the upper right corner?
Some networks have firewall restrictions which lead 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. -
Some systems of certain old vehicles can not be tested.
The SmartLink C dongle supports CAN BUS and DolP communication protocols, but some old vehicle uses K-Line communication protocol. -
Is it necessary to re-ignite the car after the diagnostic system starts working?
For the sake of some vehicle conditions, the re-ignition will provide you with a more detailed analysis after OBD diagnosis. -
Can I use Smartlink C to test heavy-duty vehicles?
Due to vehicle voltage limits, only a few heavy-duty vehicles are supported. -
Can I charge the Smartlink C dongle through an external DC power supply?
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. -
Does Smartlink C support Bluetooth communication?
Not yet. -
How to update the Smartlink C system?
After the SmartLink C dongle is powered on and connected to the network, a message “Whether to upgrade now?” will be displayed if a new system version is detected. Tap Yes to start updating, wait until the upgrade is complete.
Alternatively, the SmartLink C dongle also can be updated on the PC via LAUNCH’S J2534 tool.
Appendix – DLC Location
The DLC (Data Link Connector) is typically a standard 16-pin connector where
diagnostic code readers interface with the vehicle’s onboard computer. The DLC
is usually located 12 inches from the center of the instrument panel (dash),
under or around the driver’s side for most vehicles. DLC is not located under
the dashboard, a label should be there telling the location. For some Asian
and European vehicles, the DLC is located behind the ashtray and the ashtray
must be removed to access the connector.
If the DLC cannot be found, refer to the vehicle’s service manual for the
location.
