Automobile Inspection Notes
Should operate the machine according to safety rules in auto repair industry. Special attentions should
be paid in order to prevent the machine from being affected or damaged because of the environmental
factors such as the surrounding pH, poison gas, high pressure, heavy objects, etc.

Vehicle battery fluid contains sulfuric acid, while sulfuric acid is corrosive to the skin. Therefore, in
operation you should protect your skin from directly contacting with battery fluid. Particularly, make
sure that they won’t splash into your eyes. You should also avoid closing to fire. 

Engine exhaust emissions contains a variety of toxic compounds, so you should protect yourself from
inhaling them. During operating, the vehicle should be parked in a well-ventilated place. 

The temperature of the working engine is high, so you should protect yourself from contacting with high
temperature components such as water tank and exhaust pipes. 

Before starting the engine, you should hold the handbrake and have gear lever placed in neutral (Guide
transmission) or P gear position (automatic transmission), so as to avoid the vehicle rushing out and
result in accidents when you start the engine. 

Before repairing the vehicles, you should hold parking brake well, shift transmission gear into the neutral
position or P gear, and lower the glass doors and windows on the driver's seat side. 

If the engine can be started, you should firstly warm up it to a normal temperature (water temperature
is at about 80 ℃), and close the auxiliary electrical appliances (such as air conditioning, lighting,
loudspeaker, etc.).


Find the diagnostic socket of this car, and check, confirm that whether the wires of the diagnostic
socket are in good condition, and then connect the main unit for diagnosis. Otherwise, do not test, and
avoid damage to the main unit. If necessary, you can use a multimeter to measure the voltage of
diagnostic socket. 
Instrument Use Notes
When you use FCAR series products for testing, you must handle it with care and keep them away from
heat source and electromagnetic field, so as to avoid interference with the main unit. 

When electrical components are energized, you cannot disconnect the circuit to prevent the
self-inductance, mutual inductance from attacking sensors and automotive ECU. 

When electrical equipment works normally, you should avoid putting magnetic objects close to the
vehicle control unit, otherwise the vehicle control unit may be damaged. 

Vehicle control unit or electrical components dismounting should be done only 1 minute after the ignition
switch is turned off. 
