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.
