Pipe, the negative pole of the indicator lamp diode are connected with the negative pole of the battery 5.
The concrete operating principle of the application ECU apparatus for monitoring working state, when switching 4 closure, the logic of ECU 1
Power input obtains logic power, and then, the System self-test lamp control terminal of ECU 1, power supply relay control terminal can give
System self-test lamp 2 and the low level signal of power supply relay 3, allow System self-test lamp 2 to light, and power supply relay 3 closes, work instruction
Lamp 6 is lighted, and then, ECU 1 can detect to the current demand signal and historical failure of each sensor, when detecting system is normal
The logic power input low level signal of System self-test lamp 2 can be disconnected, allows System self-test lamp 2 to extinguish, and the meeting of relay indicating light 6 one
Illuminating state directly is in, now shows that electric-control system is in normal condition with circuit, diesel engine work can be started.That is state
One：Gone out after System self-test lamp 2 is first bright, relay indicating light 6 is bright always, shows that electric-control system is in normal condition with circuit.
And if when switching 4 closure, System self-test lamp 2 and relay indicating light 6 are constantly in illuminating state, then show
ECU 1 has historical failure or current failure, it is necessary to overhaul the current failure of each sensor signal or removed with diagnostic device
The historical failure of ECU 1.That is state two：System self-test lamp 2 is bright always, and relay indicating light 6 is bright always, then shows automatically controlled list
Member 1 has historical failure or current failure.
And if when switching 4 closure, System self-test lamp 2 is constantly in illuminating state and relay indicating light 6 extinguishes, table
The ECU main power sources end of bright ECU 1 lacks power supply, it is necessary to overhaul whether power supply relay 3 is damaged with power supply relay 3 just
Whether pole and the positive terminal of battery 5 connect.That is state three：System self-test lamp 2 is bright always, and relay indicating light 6 goes out always, then
Show that the ECU main power sources end of ECU 1 lacks power supply.
And if when switching 4 closure, System self-test lamp 2 extinguishes always and relay indicating light 6 is lighted, then it represents that logic
Power supply reaches the negative pole of battery 5 by causing ECU main power source terminal voltages to draw high inside ECU 1 and passing through relay indicating light 6,
So as to the illusion that the display ECU 1 for making relay indicating light 6 wrong is working properly, this shows the ECU ground wires of ECU 1
End and the negative pole open circuit of battery 5, ECU ground terminals lack ground wire, now need to overhaul the negative of the ECU ground terminals of ECU 1
Pole is grounded.That is state four：System self-test lamp 2 goes out always, and relay indicating light 6 is bright always, then with showing the ECU of ECU 1
The negative pole open circuit of line end and battery 5.
And if when switching 4 closure, System self-test lamp 2 and relay indicating light 6 show automatically controlled all in OFF state
The logic power input of unit 1 lacks logic power, it is necessary to check whether switch 4 is in the wire between ECU 1
Off state.That is state five：System self-test lamp 2 goes out always, and relay indicating light 6 goes out always, shows the logic electricity of ECU 1
Source input lacks logic power.
This five kinds of working conditions of System self-test lamp 2 and relay indicating light 6 cover all failure modes of ECU, pass through
System self-test lamp 2 and relay indicating light 6 just quickly can identify and handle all circuits that ECU 1 is triggered by power supply
Failure, significantly facilitate the use of user.
Embodiment described above is only that preferred embodiment of the present utility model is described, not new to this practicality
The spirit and scope of type are defined.On the premise of the utility model design conception is not departed from, ordinary people in the field is to this
The all variations and modifications that the technical scheme of utility model is made, the scope of protection of the utility model, this practicality all should be dropped into
New claimed technology contents, all record in detail in the claims.
