Preferably, the mobile terminal is mobile phone.
Preferably, the fault history storage unit is periodically updated.
The present invention also provides a kind of Diagnosis method of automobile faults, include the following steps：
Step 1：It is initialized after system electrification, onboard diagnostics terminal determines whether normally to obtain Vehicle Electronic Control list
If the data information of member sends out alarm signal abnormal；
Step 2：Onboard diagnostics terminal obtains the first car status information by electronic control unit connected to it；
Step 3：The malfunction history data of onboard diagnostics terminal read failure history storage unit, according to the first car status information
Local fault diagnosis is carried out with malfunction history data；If there is the event consistent with the first car status information in malfunction history data
Hinder code, then diagnostic result is produced, and failure code is sent to customer mobile terminal by unit by radio communication, if failure is gone through
The failure code consistent with the first car status information is not present in history data, then by radio communication unit by the first vehicle
Status information is sent to remote fault diagnosis server；
Step 4：Remote fault diagnosis server generates diagnostic message according to the first car status information and obtains order, and will diagnosis
Acquisition of information order is sent to wireless communication unit, and diagnostic message is obtained order and is sent to onboard diagnostics end by wireless communication unit
End；
Step 5：Onboard diagnostics terminal obtains order the second car status information of acquisition according to diagnostic message, and by the second vehicle shape
Unit is sent to remote fault diagnosis server to state information by radio communication；
Step 6：Remote fault diagnosis server carries out failure according to the first car status information and the second car status information and examines
It is disconnected, diagnostic result is generated, and diagnostic result is sent to customer mobile terminal；
Step 7：The diagnostic result of remote fault diagnosis server is synchronized in fault history storage unit.
It is described diagnostic result is sent to customer mobile terminal after further include following steps：
