�.12 Notes for operation of automobile
E�U
Pay attention to the following when diagnosing the au-
tomobile equipped with computer control system:
R
Do not put the magnetic objects, such as radio
loudspeaker near the computer, because the magne-
tism of the loudspeaker will damage the circuits and
parts in ECU;
R
Never switch off the internal electrical devices when
the ignition switch is on. The self-induction of the
coil when power-off will generate high instantaneous
voltage that will damage the sensor and ECU;
R
Special attention shall be paid to avoid damaging
ECU and sensor when carrying out maintenance near
the computer or sensor;
R
Connect the ECU harness connector securely, other-
wise it will damage the electronic units, such as
integral circuit in ECU;
R
Wear earthing metal strap with one end on the body
and another end twisting finesse when repairing or
approaching ECU-control digital instrument;
R
Shut down ECU system power before welding on the
automobile;
R
Unless specified, do not test the electrical devices
related to ECU with test lamp to avoid damaging ECU
or sensor;
