FCAR F804 is a diagnostic tool for the construction machinery vehicles based on the Android tablet, is our answer to folks needing a stand alone, full featured scan tool for working on Agricultural, Construction, Mining and other Off-highway applications. Diagnose and repair loaders, dozers, street sweepers, excavators as well as other utility vehicles and equipment. It is currently the only scan tool that can diagnose both construction machinery and heavy trucks.

What Can FCAR F804 do for you?

• Construction Machinery Doctor: Do in-depth and comprehensive diagnosis of construction machinery and equipment such as Caterpillar, Komatsu, John Deere, Volvo, Kubcat , Case, Hitachi and Yanmar.
• Advanced DPF Regeneration: Forced DPF regeneration for Caterpillar, Komatsu, John Deere, Volvo, Kubcat, keep you out of the big trouble of DPF filter clogging.
• All-system Diagnostics: Compared with the common diesel scanners, the FCAR F804 not only supports full system diagnostics of heavy duty trucks, but also scans all available control modules of construction machinery.
• Unique Display Wiring Diagram Function: Allows you to diagnose cummins engine through jumpers or jumper boxes, eliminating the trouble of damaged and lost diagnostic cables.
• Excellent Configuration: Equipped With a fast running Android operating system and quad-core CPU processor, built-in 1GB RAM and 8GB Flash, allowing you to easily operate it on the 800*480 high-definition display. 2.4GHz WIFI allows you to upgrade software wirelessly. Both English and Spanish are supported.

Why Need to Force DPF Regeneration?

Regeneration, or regen, of the DPF filter, is the process that burns the soot accumulation that is inside the DPF filter. An unmaintained DPF runs your vehicles unnecessarily hard and less efficient. A clogged DPF filter is also tied to your fuel mileage and can cause your truck to feel sluggish. If you can no longer start a regen then you will eventually get stuck in a derate which will then lead to an engine shut down.

In which situations is DPF regeneration required?

• The exhaust backpressure sensor is replaced.
• The PM trap is removed or replaced.
• The fuel additive nozzle is removed or replaced.
• The catalytic oxidizer is removed or replaced.
• The DPF regeneration MIL is turned on and maintenance is performed.
• The DPF regeneration control module is replaced.

Why to choose F804 to perform DPF regeneration yourself?

1) Make sure your construction machinery vehicle has enough power again (For Caterpillar, Komatsu, John Deere, Volvo, Kubcat)

If the diesel filter is clogged, the vehicle will not be able to fully use the fuel, resulting in insufficient mileage. Therefore, it is very important to clean the DPF filter regularly, which only F804 can do.

2) Save a lot of maintenance costs:

It is well known that maintenance costs at least 500-2000 dollars, but if you do the work yourself, your long-term savings will be enough to buy a new car.

3) Other benefits of cleaning your DPF filters:

Better MPG, better gas response, less frequent regenerations (passive), longer DPF life, less downtime...

Manufacturer-Level Diagnostics ( turn off the warning light).

OEM-Level Full Systems Diagnostic

FCAR F804 diesel scanner can not only support full system scanning of construction machinery vehicles conforming to standard diesel OBD protocol, such as engine, ABS/EBS, transmission, body controller, chassis controller, instrument panel system, cruise control, gateway, etc. , also supports all system diagnostics for heavy duty trucks. Meet the diagnostic needs of a variety of models!

OBD-Level Diagnostic on Engine

• Retrieve ECU Information: Read and display the control system module information detected from ECU.
• Read Fault Codes: Read the fault code information retrieved from the vehicle system module.
• Erase Fault Codes: Clear the fault code and freeze frame data retrieved from the vehicle system module.
• Review Live Data: Read and display the real-time operation parameters of the current system module.

1. Graphic: View the real-time operating parameters of the unit in the data stream waveform graph mode, and select [List] to return to the numerical display state.
2. Compare: Compare the data steam. Select a saved data file of the same vehicle type in the pop-up dialog box, and select [OK] to return, and then an additional column "CMPR values" in the data stream interface.
3. Save: Save the current data stream (for subsequent data stream comparison)

One-click multi-function: Activate, screenshot, printing, upgrade, feedback, etc. can all be completed with one-click operation

1. One-click activate: Let you easily start your first construction machinery vehicle diagnosis without complicated setup.
2. One-click upgrade: Click on the "Upgrade" menu to automatically check for the latest updates. Enjoy lifetime free updates by connecting to WiFi.
3. One-click feedback: You will get reliable and professional product support from FCAR's after-sales team through this function.
4. One-click printing: One-click generation of standardized diagnostic reports that can print diagnostic report data such as vehicle information, fault codes and data streams, and software interfaces. The resulting diagnostic report can be printed using an optional printer that you can purchase the printer at the bundle link below the link.

Superior Service that Matters!

• Humanized Pin Detect: Allows you to measure the voltage of 16 PIN of the OBD diagnostic interface and evaluate the position of the pins of the K-line and the CAN -line. It gives you clues to solve the problem when you find that the scan tool is connected to the vehicle, but the communication between the device and the vehicle cannot be established successfully.
• Enhanced Display Wiring Diagram: Allows you to diagnose the Cummins engine via a jumper or jumper box, eliminating the trouble of damaged and lost diagnostic cables. It definitely save a lot of troubles for the diagnosis work of auto repair technicians, auto repair shops, DIYers.
• Professional Data Management: Allows you to capture, view and save diagnostic reports, screenshots, and problem feedback files. Most of these files are created by performing toolbar operations on the vehicle diagnostic interface. No more worrying about data being forgotten or lost.
• Time Money Master: F804 is equipped with 4 diagnostic ports (OBDII, Diesel 6/9, CAT -9). Buying F804 is equivalent to owning 3 vehicle scanners and 1 DPF regeneration device. You will not only save a lot of money on repair shops traps, but also time on towing to a workshop.
