proper position with care.
a. If only jacking up the car in the front part or rear part, choke up the

quickly.
12. Paying attention to the following matters to avoid the damage
of components:
a. If it is not absolutely necessary, do not open the housing of the
ECU and the computers (if the IC terminals are touched, the IC
may have electrostatic damage).
b. When removing the vacuum tube, pull the end of the tube instead of
the central part of the tube.
c. When pulling the wire terminal, pull the terminal itself instead of
the wire.
d. Take care to not make the electrical components fallen, such as the
sensor or relay.
If they fall to the hard ground, they must be replaced.
e. Never use the striking wrench to remove or install the electric
thermostat or thermostat sensor.
f. When checking the conducting state of the wire connector, insert
the multimeter with care, do not bend the terminal.
g. When using the vacuum meter, do not insert the soft tube onto large
connector. Use the stepped terminal. Once the soft tube is swelled
and tightened, there may be leakage.
