The DFristCoder app is a pre-made coding app designed to code for you. To use them, all you need to do is download the DFristCoder app, sign up for an account, then purchase a device package on the official website or separately (features are available for an additional fee), select your favorite app on DFristCoder's mobile app, and click "Use". To unsubscribe from using the DFristCoder app, simply click "Unregister" in your personal account center to unsubscribe from the DFristCoder app and complete the removal of all personal information.

QD is an in-app currency that can be used to purchase feature apps. You can buy 10, 100, and 500 QDs from the DFristCoder APP. The QD required for different functional applications is different, depending on the QD displayed in the app, if you have a package plan, you can have unlimited access to all functional applications. Please note that each one-click app activation and deactivation costs credits.

Automobile manufacturers in the design and manufacture of the same level of models, almost all use the same spare parts, due to regional regulations and high and low configuration and other reasons, will be through the software will be part of the function hidden, after the vehicle off the assembly line, we can open these hidden functions on demand through the original diagnostic equipment, this process of opening is commonly known as brush hidden. DFristCoder combines the Internet and automotive diagnostic technology to launch a series of products that can be more efficient, simple and safe to open vehicle hidden functions without damage.

DFristCoder currently has more than 10K functional apps for different car makes and models. To know which ones can be used for your car, you can download the DFristCoder APP, enter the APP to select your corresponding model year, you can see the application that your vehicle can use, as well as the hidden functions of your own vehicle, the function list only shows the functions we have developed so far, but due to the difference in the factory parts of the vehicle or after later modification, a small number of functions can not be opened or have no effect after opening.
We add new feature apps every month, but if you have a specific need, you can always leave us a message on our website forum and let us know.

Brush hiding is just to open the original car support and be hidden function, will not install or plug in any module, but will not destroy the overall vehicle design, so in principle does not affect the warranty, but the 4S shop technical capabilities are different, have different attitudes towards this, the vast majority of 4S stores do not affect the warranty, a small number of 4S stores require restoration and then warranty, we have carried out cloud backup of the original car data through Internet technology, the software comes with a data recovery function, you can restore the original car data with one click.
If you have installed a hardware device and need to activate the corresponding functional application, 4S will not retain the warranty of your original car.

Don't be nervous when there is a fault code, most of them are temporary fault codes, because some ECUs will be restarted when the function is opened, and other ECUs will report fault codes when they find that he is offline, this is a temporary fault code, clear the fault code for free through our opening treasure, or unplug the VCI and start the vehicle after the operation will generally disappear.
If the fault code is caused by the loss of encoded data displayed by the software, please click on the function to restore the vehicle data once.
If the fault code is still reported after brushing and clearing the fault code, please contact customer service to solve the problem.

You can contact us through the DFristCoder official website live chat, or you can contact our online customer service by phone, our after-sales service hotline: 0755-21013241 (only during working hours) Working hours: Monday ~Sunday (9:30-17:30), non-working hours can leave a message on the official website or APP, and the customer service online will also reply in a timely manner.

OBD stands for onboard diagnostics. An OBD reader (also called a diagnostic scanner or scan tool) is a vehicle diagnostic device that can be used to read the error memory and data that is recorded on your vehicle systems.
Basically, an OBD reader allows you to establish a connection between your car and a mobile app or diagnostic software. Once the connection is established, if you are using a mobile app, you can easily access all of your car’s data from your phone!

As OBD systems became more common around the world, the Society of Automotive Engineers (SAE) recommended standardising both the data and the protocols that underpin on-board diagnostics, a recommendation that shaped the OBDII specification. OBDII provides more accurate and reliable system check data that can be accessed from a standardized OBDII data port. Vehicles manufactured after 1996 in the US and after 2001 in Europe support OBDII, and it has become the defacto standard worldwide. There are still 5 different signal protocols that OBDII might use depending make and model year, but the standardization of the OBDII port means that repair shops can use a single scan tool that works across different manufacturers and provides detailed messages with specific DTC codes.
Additionally, with the development of telematics systems, this information can often be accessed by vehicle owners on a cloud-based system in near real-time.

Most OBDII readers are only compatible with car built-in 2001 or later (gas/petrol) or 2004 or later (diesel).
If you have a vehicle 1996 on, you might need a special extension to use the OBD reader.
Additionally, depending on the OBD reader, you might only be able to use it on selected car brands only. Therefore, make sure that your car is compatible with the scan tool that you are interested in.
In the case of Carly, the Universal Scanner can be used with most car brands and the majority of vehicles manufactured from 2001 onwards. So, for example, if you have a BMW and a VW in your garage that was built after 2001 and 2004 respectively, you only need one reader instead of two.

OBDII ports are usually fairly straight forward and easy to access - either under the steering wheel column in the cab of the vehicle or beneath the dashboard. Sometimes OBDII ports are concealed behind a protective cover. If you can't find your OBDII port in locations 1–3 in the diagram below, try the other possible locations 4–9

OBDII systems collect data from Engine Control Modules and can represent the data graphically, as well as provide performance level readouts and battery usage info. Most commonly in the event of a “Check Engine Light,” OBDII diagnostic trouble codes are useful for finding a root cause to problems with vehicles and provide many types of data, including: real-time parameters, oxygen sensor test results, and data from emission control systems alongside Vehicle Identification Numbers (VINs).
Example diagnostic trouble codes (DTCs):
P-Codes: Powertrain
P0401 - Exhaust Gas Recirculation “A” Flow Insufficient Detected
P0455 - Evaporative Emission System Leak Detected (large leak)
