Operation car ECU attention
Equipped with computer control system of the car diagnostic tool when operating, we should pay attention to the following items:
-when the ignition switch, can never disconnect car interior electrical devices, because in the disconnect, because of the coil puts role, will produce a high instantaneous voltage, the voltage will cause and the damage of the sensors ECU.
-not to be radio magnetic speaker object under close to the computer place, because the magnet will damage the speaker of the circuit and components ECU.
-when in cars for welding operations, cut off the power system and the ECU in advance.
-computer or sensors in near the place repair work, should be more attention, lest damage ECU and sensors.
-in disassembling programmable read only memory, homework personnel shall be take iron, or on the static electricity will damage the ECU circuit.
-except in the test program that the special, can’t use the pointer type ohms table test ECU and sensor, and should use high impedance test of digital instrument.
-don’t use test light to test the relevant electric equipment and ECU, in order to prevent the ECU or sensor damage, unless otherwise specified.
-when people in and out when the car, the human body of electrostatic discharge can produce up to 10000 V high pressure, so the ECU control digital instrument maintenance operation, or close to the meter, be sure to wear take iron metal bands, will its end bound on the wrist, the other end caught in the vehicle body.
-should be reliable connection ECU wire connectors, otherwise it might damage the ECU internal integrated circuit and other electronic components.

Use instrument precautions
-the instrument for precision electronic instrument, use do not fall in touch.
-the test, should guarantee the instrument and diagnosis a connection between good, lest interrupt signal on test.
-don’t in the instrument of boot inserted TF card.
-finished using X-431 Diagun attention will be inserted after touching pen to host the after jack, and at the same time, to cable and joint and other accessories to put it back to avoid missing packing cases.
Gentle with-as far as possible, avoid impact.
