6. Precoated parts
Precoated parts are bolts and nuts, etc. that are coated with a
seal lock adhesive at the factory.
(a) If a precoated part is retightened, loosened or caused to
move in any way, it must be recoated with the specified
adhesive.
(b) Recoating of precoated parts
(1) Clean off the old adhesive from the bolt, nut or threads.
(2) Dry with compressed air.
(3) Apply the specified sea! lock adhesive to the bolt or nut
threads.
(e) Precoated parts are indicated in the. component illustra-
tions by the ºrº symbol.
7. When necessary, use a sealer on gaskets to prevent leaks.
8. Carefully observe all specifications for bolt tightening torques. Al-
ways use a torque wrench.
9. Use of special service tools (SST) and special service 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 procedure. 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 am-
perage rating. DO NOT exceed the rating or use one with a low-
er 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.
(See page IN±27)
(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.
It is extremely dangerous to do any work on a vehicle
raised on a jack alone, even for a small job that can be fin-
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.

1. INSPECT RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity between
terminals 1 and 3.
(b) Check that there is no continuity between terminals 2
and 4.
If continuity is not as specified, replace the relay.
2. INSPECT RELAY OPERATION
(a) Apply battery voltage across terminals 1 and 3.
(b) Using an ohmmeter, check that there is continuity between
terminals 2 and 4.
If operation is not as specified, replace the relay.
