Diode test light
Blue and white, the banana head and the connecting line should be corresponding, the diode test light is red to the positive pole, the black is connected to the negative lancet to insert the injector, and the light flashes to indicate that the signal is normal test light. If there is a phenomenon of constant light or no light, the injector signal is incorrect.
Positive and negative poles and signal lines, this product is mainly to simulate the sensor signal to observe the changes in the data stream to determine the quality of the line. At the same time, it is also possible to simulate the signal of the temperature sensor and test the post-treatment of urea.
The voltage can be measured, the hook wire is hooked by the hook of the remaining ripper, the handle is pierced, and the multimeter is connected by a connecting wire to complete the measurement of the wire.
1.5 meters long, the red line is the positive pole, the black line is the negative pole, there is a power take-off port, it is convenient to insert the test light test signal is normal, connect the twister to the multimeter
5A, 10A, 15A, 25A insurance films, a total of 37. Don't be afraid of car glitch, all kinds of safety tablets are prepared
2KΩ 1/2W 20 common resistors
How to use the injector signal: Use the slinger to puncture the two wires of the corresponding injector and connect the test lamp. If there is a signal, the test lamp will flash. If the test light is always bright or not lit
When the intake air temperature sensor simulates the temperature sensor, only 2 lines are used.
The positive and signal can be used, as well as the signal and negative.
Mainly analog: water temperature sensor, intake air temperature sensor, oil temperature sensor, fuel temperature sensor, urea tank temperature sensor, urea tank liquid level sensor, post-processing temperature sensor. After the connection is completed, turn the knob signal line, the voltage will change between 0-5V, to determine the quality of the line.
