For ease of understanding, the following describes a specific process in an embodiment of the present application, and with reference to fig. 1, an embodiment of a data display method for a vehicle diagnostic apparatus in an embodiment of the present application may include:
101. receiving a fault code data message sent by the vehicle-mounted ECU equipment;
when a vehicle breaks down and needs to be diagnosed, the vehicle diagnosis device can be adopted to send a data reading request to the vehicle-mounted ECU device, and after receiving the request, the vehicle-mounted ECU device can send a fault code data message to the corresponding diagnosis device.
102. Analyzing the fault code data message to obtain a fault code PCBU code;
after receiving the fault code data message sent by the vehicle-mounted ECU device, the vehicle diagnostic device may analyze the fault code data message according to a preset communication protocol analysis rule to obtain a fault code PCBU code (i.e., a fault code). The fault codes of the vehicle can be classified into four categories, which are respectively called as PCBU codes, wherein p (powertrain) codes are fault codes corresponding to a power system, c (chassis) codes are fault codes corresponding to a chassis, b (body) codes are fault codes corresponding to a vehicle body, and u (network) codes are fault codes corresponding to a communication system.
103. And inquiring the description text corresponding to the PCBU code according to the preset mapping relation, and if the description text corresponding to the PCBU code is not inquired, displaying the PCBU code.
A plurality of description texts are stored in the vehicle diagnosis equipment, and each description text comprises fault description information corresponding to one PCBU code. After analyzing the PCBU code in the data packet, the vehicle diagnostic device may query, according to a preset mapping relationship, an explanatory text corresponding to the PCBU code, and if the explanatory text corresponding to the PCBU code is not queried, display the PCBU code, or may refer to the fault code as "undefined fault code, please query a related manual". Maintenance personnel can inquire a relevant manual based on the PCBU code, and the purpose of quickly positioning the vehicle fault is achieved.
Optionally, when the description text corresponding to the PCBU code is queried, the queried description text may be displayed. For example, the PCBU code is replaced with the title of the searched explanatory text, and the PCBU code is not displayed, but only the title of the explanatory text and the text content are displayed.
In the embodiment of the application, the vehicle diagnosis device can receive the fault code data message sent by the vehicle-mounted ECU device, analyze the fault code data message to obtain the fault code PCBU code, and display the analyzed PCBU code when the description text corresponding to the PCBU code is not inquired according to the preset mapping relation. The PCBU code-based vehicle fault locating method has the advantages that maintenance personnel can conveniently inquire related manuals based on the PCBU code, vehicle faults can be located quickly, and the success rate of vehicle diagnosis is improved.
On the basis of the embodiment shown in fig. 1, in order to facilitate quick vehicle fault location, the vehicle diagnosis device in the embodiment of the present application may further provide a fault information query function.
