FAQ about Using the ONE VCI with OEM Software

      2. Click the Refresh button in the upper right corner to reload the page.
      3. If the problem persists, it is recommended to provide the device SN to the after-sales service.

Q: What should I pay attention to when updating the driver on the RLink Platform?
A: When updating the driver, it is recommended to close the OEM software. If the OEM software is running, the driver update will fail.


Q: Are there any charges for driver updates for ONE VCI?
A: No. Once you have purchased the ONE VCI device and driver, all software, firmware, and driver updates are free for life.


Q: Can I use the ONE VCI device without an Internet connection?
A: Yes. After binding and activating the RLink device and downloading the corresponding driver on the RLink Platform, you can perform vehicle diagnostics offline, except when using online diagnostic software or BMW diagnostic software.


Q: What is the difference between OEM software and integrated diagnostic device?
A: 1. OEM software typically contains newer, more comprehensive, accurate, and detailed data information compared to that of integrated diagnostic equipment.
     2. In terms of vehicle programming, using OEM software can achieve programming that integrated diagnostic devices cannot.


Q:Does ONE VCI support diagnostics for DOIP vehicles in conjunction with OE software?
A:It is not supported. The ONE VCI only supports working with J2534 standard software to diagnose non-DOIP vehicles.


Q: The device is connected properly, but the OEM software still cannot recognize the vehicle's VIN code. How to solve it?
A: 1. Check whether the vehicle's ignition switch is on.
    2. Check whether the driver is downloaded correctly. (Note: If there is another driver, uninstall it.)
    3. Open the OEM software and check whether the selected diagnostic VCI is "RLink".
    4. Check whether there are any updates for the ONE VCI firmware If so, it is recommended to update it.
    5. Check whether there is any software update for the RLink Platform, and check whether the drivers are updated. If so, it is recommended to update them.
    6. If the above faults are eliminated, it is recommended to restart the OEM software. (Connection bug sometimes may occur in the OEM software.)


Q: Can I diagnose the vehicle if the wrong driver mode is selected?
A: It is recommended to select the correct driver mode. 
Note: If the wrong drive mode is selected, vehicles from most brands cannot be diagnosed. However, for a few brands, it may be possible to diagnose the vehicle, but the diagnostic results may be inaccurate.


Q: The device is connected to the vehicle properly, but the RLink Platform prompts that the device is not connected and the vehicle is connected. How to solve it?
A: 1. Check whether there is an update for the RLink Platform firmware. If so, update it.
    2. It is recommended to restart the RLink Platform and re-plug the VCI of the ONE VCI.
    3. Check whether any third-party brand drivers of similar products are installed.
Note: For non-BMW OEM software systems, check whether the BMW driver has been downloaded. If the BMW driver has been downloaded, it is recommended to uninstall it and try again.



Q: Are there any tutorials or videos on how to use the OEM software with RLink devices?
A: Yes, we have provided instruction documents for each OEM software brand compatible with RLink devices. You can find these resources at https://service.topdon.com/portal/en/kb/topdon/RLink-diagnostic-series.



Q: After the driver is downloaded, can I close the RLink Platform when using the OEM software for local diagnostics?
A: Yes. The RLink Platform is only required when running the BMW OEM software. Closing the RLink Platform will cause diagnostic failure.



Q: Where can I download and install OEM software?
A: 1. You can purchase and download OEM software from the official websites of the respective vehicle manufacturers. For details, visit the OEM software download pages provided by each brand.
     2. If you need assistance with the installation process, you have the option to purchase the software through third-party channels that may offer installation support.
Note: OEM software is not included with the ONE VCI devices and must be purchased separately.



Q: Does ONE VCI support the function of cloning module data?
A: ONE VCI are VCI devices compatible with OEM software from various vehicle brands, and can serve as replacements for the OEM diagnostic VCI. The capability to clone module data is contingent upon the specific functions supported by the OEM software you are using.



Q: When I open the OEM software for diagnostics, I receive a prompt stating that the vehicle cannot communicate with the VCI, which prevents the vehicle from being diagnosed. How can I resolve this issue?
      A: 1. Check if you have downloaded the VCI diagnostic driver. If not, download the driver first.
          2. Check if you have switched VCI and selected RLink mode in the OEM software. If not, select RLink diagnostic mode first.
          3. Check if the vehicle ignition switch is turned on. If not, turn on the ignition switch before diagnosing.
          4. Check if the voltage of the vehicle is lower than 12 V, as some vehicles cannot be diagnosed under such conditions. If the voltage is low, connect a power supply to the vehicle or start the vehicle for diagnostics.
