ECU REPAIR TOOL(FULL)
ENGINEERS’ POWERFUL ASSISTANT
Equipment Description
NED—3058,testing-analyzing equipment of automobile’s EECS and ECU, is specially designed for engineers who repair automobile’s EECS and ECU. It is a handset and also can be used at worktable. It includes electric-control analyzing equipment and signal generator. According to the common characteristic if automobile’s EECS, the equipment can simulate 8 kinds of signals to meet the demands of diagnosing work. Moreover, the equipment can simulate 3 kinds of independent, changeable signal combination at the same time. The equipment is designed on the basis of electric-control principle and repairing regularity, so it can also be a useful teaching tool to grasp Automobile-Electric technique in automobile repairing skill training.
Brief Introductions of Functions
Panel’s Display:
1,Digital display of signal’s frequency.
2,Strip display of DUTY.
3,LED display of signal output.
4,Digital display of injection pulse width.
5,Strip display of output voltage.
6,LED display of drive signal output.
7,LED display of external signal input.
The function of simulating sensor signal:
1,58+2 signal (58Hz—900Hz), simulate crankshaft position signal. Have 2 shifts: 5Vpp, 10Vpp.
2,Sin wave signal (20Hz—900Hz), simulate car speed, gear speed, have 2 shifts: 5Vpp, 10Vpp.
3,Rectangle wave (10Hz—10KHz), simulate various kinds of digital signals, have 2 shifts: 5Vpp, 10Vpp.
4,One way changeable resistance signal(50Ω—10KΩ),simulate cooling water temperature, loopy electric potential utensil knob (12) precisely adjusts to output.
5,One way changeable voltage signal (0—10V), simulate various kinds of voltage signals; loopy electric potential utensil knob (12) precisely adjusts to output.
6,PWM signal (5Hz—200Hz; 5%—90%), frequency, DUTY can be adjusted independently. Puls and quite the contrary output, (simulate Cylinder Identification signal, ignition module input signal.
7, PWM drive signal (5Hz—200Hz; 5%—90%;
The function of measuring:
1,Examine external injection pulse width. (0.00—99.99ms)
2,Examine external voltage (0—10V).
3,Examine external signal’s frequency (0—9999Hz).
4,Examine external signal’s DUTY (5%—100%).
5,Examine external impulse with flashing LED.
The function of active testing:
1,When simulating signals like voltage, resistance, frequency, you can observe injection pulse width simultaneously.
2,You can examine the injection pulse width of an engine’s starting status.
3,By means of observing injection pulse width (ms), you can do these tests to the Electronic Fuel Injection engine:
Add rich mixture at cold starting;
Add rich mixture at running;
Add rich mixture at Idle;
Adjust AFS;
Feed back capability test of Oxygen signal under closed loop status;
Sever Fuel test;
MAP test; etc.
4,You can test the battery voltage of the engine’s stating status.
5,When observing signal’s frequency and pulse width, you can examine signal’s voltage and DUTY at the same time.
6,The blue LED can do the induce test of ignition high tension
