Complete DPF Service Functions 

DPF Regeneration ( Fit for Cummins, Detroit, Caterpillar, Paccar​ engine )

DPF Regeneration is used to clear PM (Particulate Matter) from the DPF filter through continuous combustion oxidation mode (such us high temperature heating conbustion, fuel additive or catalyst reduce PM ignition conbustion) to stabilize the filter perfornance. ​ Avoid costly replacement of the filters. Lower Overall Maintenance Costs.

DPF regeneration may be performed in the following cases:

(a) The exhaust back pressure sensor is replaced.

​​(b) The PM trap is removed or replaced.

​(c) The fuel additive nozzle is removed or replaced.​

(d) The cataytic oxidizer is removed or replaced.

​(e) The DPF regeneration MIL is on and maintenance is performed.

​​(f) The DPF regeneration control module is replaced.

Operate Notice

DPF regeneration ensures that the vehicle state meets the following requirements:

1. First of all, when dpf is regenerated, the vehicle needs to ensure that the vehicle speed is 0, and the brake pedal, clutch pedal and accelerator pedal of the vehicle are in a normal relaxed state, that is to say, the accelerator, brake and clutch pedal of the vehicle are not stepped on.

2. In addition, the gear of the car needs to be kept in the neutral position, and the dpf regeneration function cannot be turned on with gear. At the same time, the hand brake of the car should be tightened.

3. In the process of starting the regeneration function of automobile dpf, it is also necessary to ensure that the engine of the automobile is always in an idle state, and the temperature of the automobile water tank is best kept above 40 degrees Celsius.

4. Engine running at idle speed, and water temperature should be higher than 80 Celse Degree. 

5. Coolant temperature is higher than 60″C Degree;  Fuel temperature is lower than 70″C degree; 

The above conditions are necessary for the dpf regeneration process. If any of the above conditions are not met, the dpf function of the car will not work normally at this time.

One-click Activation

When you first use the truck tool for diagnosis, fill in the valid user information, no other complicated processes, directly click Activate and can be activated to use.

One-click Screenshot

If you encounter important data during vehicle diagnosis that needs to be analyzed again later, you can take a screenshot and save it first, and you can view, modify or delete it in Data Management at any time.

One-click Create, Email share and Print Diagnostic Report

With the truck diagnostic scanner, a vehicle diagnostic data is generated after you perform a vehicle diagnostic. You can create a vehicle health report, and then send the test report to yourself to the mailbox (the mailbox server is google) or share it with your friends. And also print the vehicle information, fault codes, live data and other data reports, as well as the software interface can also be printed. Easy for you to view, analyze and carry. Please note that you need to use this feature while connected to WiFi.

One-click Feedback

This scan tool allows you to use this function to send diagnostic problems back to our technical team, and then you can always get our professional technical team to analyze and solve the problem for you. We provide technical support directly online, so there is no need to go out and find a repairer or pay extra for repairs.

One-click Lifetime Update

We will keep developing new features all the time, improve the deficiencies of old features, fix heavy truck scan tool problems, and will update the device version regularly. You don’t need to update on your computer or other TIF card to update, you can get the latest version for free with just one click to update. (It is recommended that you can upgrade your device every 1-2 months by connecting to WIFI)

About Update:

1.Enter (Settings), turn on (WiFi).

2.Enter (Update) in the function main menu, and the system will automatically search for the latest update program. Click (Update) to upgrade the model and other applications to the latest version.

Warm tips: Perform VCI and application upgrade first, then vehicle database upgrade. If it is already the latest version, you can update it after a while, we usually update the device from time to time.

Pin Detect

Auto pin detect function automatically measures the voltage of the OBD diagnostic interface and determines the pin positions of the K line and CAN line.

Warm tip: The test needs ECU no response, please let the customer check whether the diagnostic interface has voltage first.

Simulate & DEMO

HD3400 truck code reader has a simulation function, which can demonstrate the diagnostic interface for you. The information in these menus is collected based on past actual vehicle diagnostics, in order to better understand the product functions for users, and make HD3400 truck diagnostic scanner more plain and easy to understand.

Please note: Simulation and demo are demo menus, not diagnostic function menus, no diagnostic operation can be performed.
