7. When necessary, use a sealer on gaskets to prevent
leaks.
8. Carefully observe all specifications for bolt tighten-
ing torques. Always use a torque wrench.
9. Use of special service tools (SST) and special ser-
vice materials (SSM) may be required, depending on
the nature of the repair. Be sure to use SST and SSM
where specified and follow the proper work proce-
dure. A list of SST and SSM can be found at the back
of this manual.
10. When replacing fuses, be sure the new fuse has the
correct amperage rating. DO NOT exceed the fuse
amp rating or use one of a lower rating.
11. Care must be taken when jacking up and supporting
the vehicle. Be sure to lift and support the vehicle at
the proper locations.
(a) If the vehicle is to be jacked up only at the front or
rear end, be sure to block the wheels 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 the vehicle raised on jack alone, even for a
small job that can be finished quickly.

(a) If the vehicle is to be jacked up only at the front or rear end,
be sure to block the wheels at the apposite end in order
to ensure safety.
(b) After the vehicle is jacked up, be sure to support it on stands.

ished quickly.
12. Observe the following precautions 'to avoid damage to the parts:
(a) Do not open the cover or case of the ECU unless abso-
lutely necessary. (If the IC terminals are touched, the
IC may be destroyed by static electricity.)
(b) When replacing the internal mechanism (computer
part) of the digital meter, be careful that no
part of your body or clothing comes in contact with the
terminals of the leads from the IC, etc. of the replace-
ment part (spare part).
(c) To disconnect vacuum hoses, pull on the end, not the middle
of the hose.
M To pull apart electrical connectors, pull on the connector
itself, not the wires.
(e) Be careful not to drop electrical components, such as sen-
sors or relays. If they are dropped on a hard floor, they
should be replaced and not reused.
