DFH, ENGINE: DONGFENG Diagnostics

Manual diagnosis process of the system through display codes, blinking codes…

Allows to read the ECU failure memory by providing the user information about the error codes detected in it. This function allows the user to carry out the deleting of the errors memory; logically if the error is present, it will be detected again by the ECU and it will be displayed in the following diagnosis.

Displays on the screen the values of the different sensors connected to the ECU. It depends on each system.

They are the direct tests that can be done with the system components. For example, actuate an ABS modulator, activate the suspension solenoid valves in order to raise or low the vehicle chassis,... It is the active diagnosis, which, for example for the engine, allows to carry out tests calibrating its state, like the cylinders balance, cylinders cutout or compression. Depends on each system.

These are the technical data of the ECU, serial number, software version, manufacturer's reference, etc. It depends on each system.

Some ECU can operate with different configurations. With this option you can copy configurations and parameters to the control unit, so control units can be programmed in its first installation. For certain systems even the modification of some parameters not affecting the vehicles security is allowed.

Some systems ask to calibrate some components for its correct operation. The best example are the electronic suspensions, in which there must be stored the reference values so the ECU can make function correctly.

This point refers to the reset of the control units maintenance counters. If the maintenance operations are completed but the maintenance alarm is not cancelled, the warning message referring to maintenance will keep on. It has nothing to do with the clearing of the error codes from the memory, which is part of the diagnosis.

Technical information of the system indicating the checking values, descriptions, graphics, charts…

Detailed diagram of the system containing added information on configuration, components, locations and notes which make the diagnosis easier.

Technical information of vehicles including all the motorization technical data, tightening torques, capacities, graphics and other checking values…

Section in which the maintenance intervals are displayed, indicating the operations to be performed on the vehicle, and through which the reports that make the customers management easier for the workshop can be obtained.
