Network technology for remote access to vehicle scanning tools

Remote car service eliminates the need for on-site equipment and experts. Technicians can use FlexiHub software to remotely receive OBD fault codes and sensor data from remote vehicles over the internet. This software can redirect data over the network, allowing communication between the technician's diagnostic software and remote testing equipment attached to the car. Remote diagnostics has many benefits, including reduced service costs, time savings, and increased flexibility for service specialists.
To run FlexiHub-based OBD2 vehicle diagnostics, you will need:

OBD diagnostics with FlexiHub - use cases

OBD diagnostics
Performing remote vehicle diagnostics can be challenging. FlexiHub is a software solution that simplifies the process. Remote OBD access can be established by running FlexiHub on an Android device that is connected to a vehicle using an OBD cable or BlueTooth connectivity. A technician can access the Android device over the network from a remote computer and get diagnostic information as if they were standing next to the vehicle.

  • Using FlexiHub is simple with the following steps.

    • Open a FlexiHub account.
    • Connect an OBD scanner to the vehicle in question and to your Android device.
    • Install FlexiHub on an Android device.
    • Launch FlexiHub on an Android device and access the OBD scanner using the software’s user interface.
    • Connect to the Android device from a remote computer using the same FlexiHub account credentials.
    • View diagnostic information transferred from the ODB scanner on a remote, network-connected computer.

  • Use cases of using flexihub on an Android device

    “I’ve been able to expand my business and deliver first-rate customer service by implementing remote diagnostics using Android devices running FlexiHub. I can now help my clients when they have issues no matter where they are located without physically visiting the vehicles. Using Android devices and an OTG cable, my customers send me the information I need to determine what needs to be done with their vehicles. This lets me get them back on the road quickly or suggest preventative maintenance to avoid major problems.”

Some other usage scenarios:

Data from cars goes directly to diagnjstic app

We have 10 server computers running different car manufacturer OEM applications. We also have 5 laptops/tablets in the field with USB ports to connect to cars that are used to send the data from cars to the OEM app computers for diagnostics, etc.

Thanks to FlexiHub, we managed to receive USB signals on the 10 OEM app computers from the remote laptops and tablets in the field regardless of how far they are located physically.

We get diagnostic over the Internet

The diagnostic program we rely on is installed on one of the computers in our central office. We have several service centers countrywide. Coming to the remote centers, customer cars are connected to our laptops via USB ports. With the help of FlexiHub, the data we receive from the cars are then transmitted to the diagnostics computer over the internet connection.

VAG Coding Specialist

Remote connection to client's car is possible

I was in the process of creating my machine repair business on-site and needed a software tool to connect to my customers' USBs remotely. I didn’t want to share a USB but connect to my clients'. I opted for FlexiHub to get remote access to USB interface boxes and now I can perform customer troubleshooting over the internet.

Reprogramming the data from school buses remotely

We supply GPS tracking units to school buses and wanted to reprogram such units remotely by connecting them to a laptop or/and an Android device and then sharing it with our office engineer. We were planning on using the cell phone connection for that. So far FlexiHub works perfectly well and allows us to automate the workflow as much as possible.

CEO of the Transportation company

Better data transfer speed

We rely on FlexiHub specifically for remote access to program client vehicles from our location. On a rare occasion, we ran into issues where both users had good data transfer speeds on the internet network but the USB device was transmitting very low speeds & would not ping.

To eliminate the latency issues, we deployed the FlexiHub Private Tunnel Server. Now we use this solution on a regular basis as it lets us provide remote assistance worldwide without any delays.

Where USB Network Gate fits in automotive

  • Multi-bay workshops — share one OBD2 scanner or J2534 adapter across all service bays over the shop LAN.
  • Fleet operators — field laptop with scanner connects to head-office diagnostic PC over VPN; no scanner needs to travel back to base.
  • Dealer service centers — centralize dealer-issued diagnostic dongles (Cummins INSITE, CAT ET, ODIS) on a server; technicians connect per-session.
  • Remote desktop diagnostics — run your diagnostic software inside RDP or a virtual machine; UNG passes the physical OBD scanner through to the virtual session.
  • VAG / brand specialists — share a single VCDS interface across multiple technicians without buying additional licenses.

Benefits of remote vehicle diagnostics

  • Improved fleet productivity

    A vehicle waiting in a repair shop seems to be a nightmare for any truck company owner. Unable to deliver cargo to the required location and pick up a new one, a truck that has broken down on the road can lead to financial and reputational losses.
    Instead, preventing vehicles from failing by using remote diagnostics tools will eliminate truck downtime problems, increase productivity, and save your company significant time and money.

  • Centralized car management

    Being one-by-one with the issue, the driver may lack the qualification or experience to make the best decision concerning the vehicle repair. By sending car data to the administrator for in-depth analysis, the remote fleet management system may help to find the best solution and determine whether the car needs immediate servicing or may wait for some time.

  • Saving costs on vehicle repairs

    Another benefit you get if performing remote vehicle diagnostics is reduced repair costs due to timely car inspections and maintenance. It is much cheaper to identify and fix a small problem immediately than wait until it causes a breakdown and the car will require a soft and time-consuming repair.

  • Overcoming distance limitations

    Even if the truck is in another country or in another part of the world, you can still be aware of its condition and provide immediate assistance when needed. You just need to use proper truck fleet management software.
