1. Definition of a computer diagnostic machine for car failure
The vehicle electrical system failure diagnostic machine is also known as the car failure computer diagnostic machine. The car fault diagnoser is a device used to interact with the automobile eu and to translate the information into a language and format that can be easily viewed. The auto failure computer diagnostic machine, which communicates with the auto self-diagnostic system in accordance with the communications protocol followed by the auto self-diagnostic system, acquires equipment for the analysis of vehicle-related data parameters in the auto self-diagnostic system。
Note: this paper is limited to the discussion of this equipment, which interacts with information via the diagnostic interface for the external export of vehicles from the eu (usually 16 pins)。
2. Hardware component of the car failure diagnostic machine
An information instruction entered for the user communicates functional requirements to a diagnostic device, such as a key, touch screen, knob, etc. Some of the equipment also has extended input interfaces such as usb, microphones, cameras, etc., which are not directly required for diagnostic functions。
The display interface presents the real-time communication information and state of the euu, which is accessible to users and long for display screens or indicator lamps. The first two functions may also be performed on the same device, such as touch screens providing the display of functional options for input and information output。
The implementation of the functional component enables the interaction of diagnostic instruments with vehicle information, such as diagnostic modules, diagnostic connection lines (or wireless transmissions such as bluetooth) and messages from diagnostic instruments to the eu and receiving feedback from the ecu。
Conversion and comparison of resolves such as instructions from users, feedback received from the eu to the same format, i. E. Core components such as cpus of equipment。
3. Common car failure diagnostic brands and models
Totung autel, yuan launch, boschbo, kenyon redbox, kim benteng, afka, samhara sysokean, okrea, ads, langin
4. Main functions of the car failure diagnostic machine
5. Practical application of vehicle failure diagnostic devices
1. Operational guidance:
2. Selecting special functions
3. Select maintenance lamps to zero
4. Selection to zero oil (small maintenance)
5. The engine of the vehicle does not have a t, choosing 7500 km 180 days (without t)
Six, no sign, no sign, no sign
7, esi reset, click reset
Zero-eight successful, signlights out, function successfully
