After the device been connected with vehicle, before starting the engine, be sure to pull the parking brake, and put
the speed lever in neutral (manual gearbox), or parking (automatic transmission).
Car battery liquid containing sulfuric acid, sulfuric acid on the skin corrosive, the operation should avoid the battery
liquid and skin in direct contact, can not be splashed into the eyes.
When the engine is running, avoid contact with high temperature parts such as water tanks and exhaust pipes.
When the battery holder is energized, do not use it to hold the body.
Precautions for instrument use
The instrument for precision electronic equipment, do not fall.
The first time open device, the instrument may respond slowly, please be patient, do not frequently operate the
instrument.
The display may flash once when ignition, is a normal phenomenon.
If the display flashes, the program is interrupted, please turn off the power, re-boot device.
Ensure that the instrument and diagnostic port are well connected to avoid signal interruption affecting the test. If
you can not connect properly, please unplug the connector once again, do not shake the joints in the process of use.
When using cables and connectors, use screws to avoid disconnection and damage to the interface when moving.
When connecting the connector, hold the front of the connector and avoid pulling the rear connection cable.
Try to gently, placed in a safe place, to avoid the impact, disconnect the power when not use.
Operation of the instrument need to have a certain basis for car testing and maintenance, the measured car
electronic control system has a certain understanding.
Precautions of ECU diagnosis
When handling a vehicle equipped with ECU, the following should be noted:
Can not place magnetic objects such as radio speakers near the ECU, because the magnetic properties of the
loudspeakers can damage the circuits and components in the ECU.
When the ignition on, must not disconnect the car inside the electrical device, due to the coil when the
self-inductance, will produce a high instantaneous voltage, this voltage will cause damage to the sensor and ECU.
When handling repair work near a computer or sensor, special care should be taken to avoid damage to the ECU
and the sensor.
Should be connected to the ECU wiring harness connector, otherwise it may damage the ECU internal integrated
circuits and other electronic components.
During the maintenance of digital control of the ECU or near the instrument, be sure to wear a metal belt, and one
end of the car body, the other end wrapped around the wrist.
When the welding operation on the car, the power should be cut off in advance of the ECU system.
Do not use test lights to test electrical equipment related to the ECU to prevent damage to the ECU or sensor unless
specified.
Except the special instructions in the test procedure, the ECU and the sensor can not be tested with a pointer-type
ohmmeter, but should be tested using a high-resistance digital meter.
