Data packet is to preset storage inside module.
6. a kind of ECU quick diagnosis terminal according to claim 5, which is characterized in that between the S1 and S2 further include:
If the electric current is greater than predetermined current threshold, it is low to export the ECU reparation success rate, and dodge by preset indicator light
Bright early warning, diagnosis terminate.
7. a kind of ECU quick diagnosis terminal according to claim 5, which is characterized in that the S2 specifically:
If the voltage is in default normal voltage range, and the electric current then passes through default in predetermined current normal range (NR)
CAN module receive ECU send message information；
If being successfully received message information, S3 is thened follow the steps；
Otherwise, it is low to export the ECU reparation success rate, and early warning is flashed by preset indicator light, diagnosis terminates.
8. a kind of ECU rapid diagnosis system, which is characterized in that including first processor, power supply monitoring module, CAN module, interface
Harness, memory module, power module, wireless module and status indicator lamp；
The first processor respectively with power supply monitoring module, CAN module, memory module, power module, wireless module and state
Indicator light connection；The power supply monitoring module and CAN module pass through interface harness respectively and connect with ECU, the wireless module with
The background server of peripheral hardware connects；
The power module includes Power Management Unit and mobile power source, Power Management Unit respectively with first processor and movement
Power supply, the mobile power source are connect with first processor；
The power supply monitoring module, the voltage and current of ECU when for monitoring, and monitoring result is sent to the first processing
Device；
The CAN module, for obtaining the message information of ECU transmission, and the information that E-Packets is to first processor；
The first processor, for the voltage as ECU in default normal voltage range, and the electric current of ECU is in predetermined current
In normal range (NR), then controls CAN module and obtain the message information that ECU is sent, and receive the message information of CAN module forwarding；It reads
The message information after receiving is taken, the storage information and fault message of the ECU is obtained；ECU is diagnosed according to fault message,
Obtain diagnostic result；According to diagnostic result, if the ECU unrepairable, state of a control indicator light flashes early warning, Ruo Kexiu
Multiple, then state of a control indicator light shows green；And be packaged storage information, fault message and diagnostic result, it obtains
To data packet；
The memory module, is wrapped for storing data；
The wireless module, for sending data packet to background server；
The status indicator lamp, for showing color corresponding with diagnostic result.
