2. INSPECT HIGH±TENSION CORDS
(a) Remove the V±bank cover.
(b) Disconnect the high±tension cords from the spark plugs.
(1) Using needle±nose pliers, disconnect the cord
clamp from the engine wire protector.
(2) Disconnect the high±tension cords from the spark
plugs.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.
(3) Disconnect the high±tension cords from the clamp.
(c) Disconnect the high±tension cords from the ignition coils.
(1) Using a screwdriver, lift up the lock claw and discon-
nect the holder from the ignition coils.
(2) Disconnect the high±tension cord at the grommet.
NOTICE:

Pulling on or bending the cords may damage the con-
ductor inside.

Do not wipe any of the oil from the grommet after the
high±tension cord is disconnected.

(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN±8).
Cancel the parking brake on the level place and
shift the transmission in Neutral (or N position).
When jacking up the front wheels of the vehicle at
first place stoppers behind the rear wheels.
When jacking up the rear wheels of the vehicle at
first place stoppers before the front wheels.
When either the front or rear wheels only should be
jacked up, set rigid racks and place stoppers in front
and behind the other wheels on the ground.
After the vehicle is jacked up, be sure to support it
on rigid racks . 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.
(l) Observe the following precautions to avoid damage to the
following parts:
(1) 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 electric-
ity.)
(2) To disconnect vacuum hoses, pull off the end, not
the middle of the hose.
(3) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(4) 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.
(5) When steam cleaning an engine, protect the elec-
tronic components, air filter and emission±related
components from water.
(6) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(7) When checking continuity at the wire connector, in-
sert the tester probe carefully to prevent terminals
from bending.
(8) When using a vacuum gauge, never force the hose
onto a connector that is too large. Use a step±down
adapter for adjustment. Once the hose has been
stretched, it may leak air.
