When performing diagnostic operations on a vehicle equipped with
a computer control system, the following should be noted:
(1) Do not place magnetic objects such as radio speakers close to
the computer, as the magnetic properties of the speakers can
damage the circuits and components in the ECU.
(2) When the ignition switch is turned on, the internal electrical
equipment of the car must not be disconnected. Due to the
self-inductance of the coil when disconnected, a high instantaneous
voltage will be generated, which will cause damage to the sensor
and ECU;
(3) When performing repairs near a computer or sensor, special
care should be taken to avoid damage to the ECU and sensor;
(4) When carrying out maintenance work on or near the
ECU-controlled digital meter, be sure to wear a metal strap with one
end clamped to the body and the other end wrapped around the
wrist;
(5) When performing welding work on a car, the ECU system
power should be turned off beforehand;
(6) Do not use test lights to test ECU-related electrical devices to
prevent damage to the ECU or sensor unless specifically stated;
(7) Test ECU and sensors cannot be tested with a pointer-type
ohmmeter, unless otherwise specified in the test procedure, but
should be tested with a high-impedance digital meter.
