12. Install the ignition coils and spark plugs.
13. Use the MUT-IIto erase the self-diagnosis codes or
disconnect the battery cable from the battery ( - ) terminal
for 10 seconds or more and then reconnect the cable.
NOTE
This will erase the diagnosis code resulting from the crank
angle sensor connector being disconnected.
MANIFOLD VACUUM CHECK
1. Set the vehicle to the pre-inspection condition.
2. Turn the ignition switch to the “LOCK” (OFF) position.
3. Set the engine tachometer or connect the MUT-II.
4. Check that the idle speed is within the standard value.
NOTE
When using the MUT-II, select the code No.22.
5. Connect the three-way union joint to the vacuum hose
between the fuel pressure control valve and the air intake
plenum, and connect a vacuum gauge.
6. Check the manifold vacuum at idle.
Limit: 58 kPa
7. Turn the ignition switch to the “LOCK” (OFF) position.
8. Remove the vacuum gauge and install the vacuum hose
in its original location.
9. Remove the engine tachometer or the MUT-II.
LASH ADJUSTER CHECK
If an abnormal noise (knocking) that seems to be coming
from the lash adjuster is heard after starting the engine and
does not stop, carry out the following check.
NOTE
(1) The abnormal noise which is caused by a problem
with the lash adjusters is generated after the engine
is started, and will vary according to the engine speed.
However, this noise is not related to the actual engine
load.
Because of this, if the noise does not occur
immediately after the engine is started, if it does not
change in accordance with the engine speed, or if
it changes in accordance with the engine load, the
source of the noise is not the lash adjusters.

(2) If there is a problem with the lash adjusters, the noise
will almost never disappear, even if the engine has
been run at idle to let it warm up.
The only case where the noise might disappear is
if the oil in the engine has not been looked after
properly and oil sludge has caused the lash adjusters
to stick.
1. Start the engine.
2. Check that the noise occurs immediately after the engine
is started, and that the noise changes in accordance
with changes in the engine speed.
If the noise does not occur immediately after the engine
is started, or if it does not change in accordance with
the engine speed, the problem is not being caused by
the lash adjusters, so check for some other cause of
the problem. Moreover, if the noise does not change in
accordance with the engine speed, the cause of the
problem is probably not with the engine. (In these cases,
the lash adjusters are normal.)
3. While the engine is idling, check that the noise level does
not change when the engine load is varied.
If the noise level changes, the cause of the noise is
probably parts striking because of worn crankshaft
bearings or connecting rod bearings. (In such cases, the
lash adjusters are normal.)
4. After the engine has warmed up, run it at idle and check
if any noise can be heard.
If the noise has become smaller or disappeared, oil sludge
could make the lash adjusters stick. Clean the lash
adjusters. (Refer to the Engine Workshop Manual.) If not
improved, go to step 5.
5. Bleed air from the lash adjusters.
6. If the noise has not disappeared even after the air
bleeding, clean the lash adjusters.
(Refer to GROUP 11B - Rocker Arms and Camshaft.)

NOTE
(1) If the vehicle is parked on a slope for a long period
of time, the amount of oil inside the lash adjuster
will decrease, and air may get into the high pressure
chamber when starting the engine.
(2) After parking the vehicle for long periods, the oil drains
out of the oil passage, and it takes time for the oil
to be supplied to the lash adjuster, so air can get
into the high pressure chamber.
(3) If either of the above situations occur, the abnormal
noise can be eliminated by bleeding the air from inside
the lash adjusters.

ENGINE -On-vehicle Service11A-14
1. Check the engine oil and replenish or replace the oil
if necessary.
NOTE
(1) If there is a only small amount of oil, air will be drawn
in through the oil screen and will get into the oil
passage.
(2) If the amount of oil is greater than normal, then the
oil will being mixed by the crankshaft and a large
amount of air may get mixed into the oil.
(3) If the oil is degenerated, air and oil will not separate
easily in oil, and the amount of air mixed into the
oil will increase.
(4) If the air which has been mixed in with the oil due
to any of the above reasons gets into the high pressure
chamber of the lash adjuster, the air inside the high
pressure chamber will be compressed when the valve
is open and the lash adjuster will over-compress,
resulting in abnormal noise when the valve closes.
This is the same effect as if the valve clearance is
adjusted to be too large by mistake. If the air inside
the lash adjusters is then released, the operation
of the lash adjusters will return to normal.
2. Run the engine at idle for 1 - 3 minutes to let it warm
up.
3. With no load on the engine, repeat the drive pattern shown
in the illustration at left and check if the abnormal noise
disappears. (The noise should normally disappear after
10 - 30 repetitions, but if there is no change in the noise
level after 30 repetitions or more, the problem is probably
not due to air inside the lash adjusters.)
4. After the noise has disappeared, repeat the drive pattern
shown in the illustration at left a further 5 times.
5. Run the engine at idle for 1 - 3 minutes and check that
the noise has disappeared.

REMOVAL SERVICE POINT
AA"DRIVE BELT REMOVAL
Due to the adoption of the Serpentine drive system with the
auto-tensioner, the following operation is required:
1. Insert the 12.7sq. spinner handle and etc. into the tool
hole of the auto-tensioner and rotate it counterclockwise
until the auto-tensioner gets to the stopper.
2. Align hole A with hole B for fixing by inserting the L-shaped
hexagon wrench, then remove the drive belt.
Caution
When the drive belt is reused, use a chalk to indicate
an arrow of rotation direction on the back of the belt
so that it can be re-assembled in the same direction
as before.
