Location of the Data Link Connector(DLC)

The DLC(Data Link Connector or Diagnostic Link Connector) is the standardized 16-cavity connector where diagnostic scan tools interface with the vehicle’s side for most vehicles. If data link connector is not located under dashboard, a label should be there telling 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.

Product update

This update function allows you to update the product software through a windows computer To upload your product, you need the following tools:

1. OBD auto meter
2. Windows PC(win xp, 7,8,10) with internet connected
3. Mini-USB cable
   Steps:
   Download and install the applications from VJOYCAR official website: http://www.vjoychina.com/uplink/
   Run uplink.exe in your computer(Not mac OS compatible) before click the “check update”, make sure that on left bottom corner, you see the “Device connected to COM X”, otherwise, please check if the driver is installed properly or not

1. Keep pressing any button of the scanner, meanwhile connect to USB cable to PC with scanner, make sure the screen is displayed “Update Mode” then released.
2. Open the uplink software, click the “Check Update”, the intelligent software and device will finish its update process on its own. The process will take around 2 minutes depends on the network connectivity.
3. During the update procedure, please do not disconnect the USB connection

Data Stream

NOTE:

• the uplink program is working for all windows series computer, please use it on official certified windows OS, otherwise the driver may not be able to install.
• some anti-virus software may give warning when install it, please turn off the anti-virus software before installation, it’s a clean and green software with authentication by google.
• please ignore the Microsoft Modem drivers install failure if you are not using windows system.
• if the product to be malfunctioning after update, it may need to reinstall the update. Hold down the any button until the product has been forced into update mode, then repeat the update installation procedure outlined above.
