the vehicle. Be sure to lift and support the vehicle at
the proper locations (See pages IN —16 to 18).
(a) If the vehicle is to be jacked up only at the front
or rear end, be sure to block the wheels at the
opposite end in order to ensure safety.
(b) After the vehicle is jacked up, be sure to support
it on stands. It is extremely dangerous to do any
work on a vehicle raised on a jack alone, even for
a small job that can be finished quickly.
the parts:
(a) Do not open the cover or case of the ECU unless
absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static ele-
ctricity.)
(b) To disconnect vacuum hoses, pull on the end, not
the middle of the hose.
(c) To pull apart electrical connectors, pull on the
connector itself, not the wires.
(d) Be careful not to drop electrical components,
such as sensors or relays. If they are dropped on
a hard floor, they should be replaced and not
reused.
(e) When steam cleaning an engine, protect the
distributor, air filter, and VCV from water.
(f) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(g) When checking continuity at the wire connector,
insert the tester probe carefully to prevent ter-
minals from bending.
(h) When using a vacuum gauge, never force the
hose onto a connector that is too large. Use a
step —down adapter instead. Once the hose has
been stretched, it may leak.
(a) When disconnecting vacuum hoses, use tags to
identify how they should be reconnected.
(b) After completing a job, double check that the
vacuum hoses are properly connected. A label
under the hood shows the proper layout.
