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.
