Aiming Adjustment
Before performing aiming adjustment, make sure of the follow-
ing.
a. Keep all tires inflated to correct pressure.
b. Place vehicle on level ground.
c. Check that vehicle is unloaded (except for full levels of
coolant, engine oil and fuel, and spare tire, jack, and tools).
Have the driver or equivalent weight placed in driver’s seat.
1. Set the distance between the screen and the center of the
fog lamp lens as shown at left.
2. Turn front fog lamps ON.
3. Adjust front fog lamps so that the top edge of the high inten-
sity zone is 100 mm (4 in) below the height of the fog lamp
centers as shown at left.
When performing adjustment, if necessary, cover the head-
lamps and opposite fog lamp.

IAlways use new valve oil seal.
Refer to OIL SEAL REPLACEMENT.
IBefore installing valve oil seal, install valve spring seat.
IInstall valve spring (uneven pitch type) with its narrow
pitched side toward cylinder head side (paint mark).
IAfter installing valve component parts, tap valve stem tip
with plastic hammer to assure a proper fit.
7. Check hydraulic lash adjusters.
a. Push rocker arm at hydraulic lash adjuster location, and see if
rocker arm moves. If it moves at least 1 mm (0.04 in), it indi-
cates that there is air in the high pressure chamber.
Noise will be emitted from hydraulic lash adjuster if engine is
started without bleeding air.
b. Remove hydraulic lash adjuster and dip in a container filled
with engine oil. While pushing plunger as shown in figure,
lightly push check ball using a thin rod. Air is completely bled
when plunger no longer moves.
Air cannot be bled from this type of lash adjuster by running
the engine.
8. Install rocker arms, shims, rocker arm guides and hydraulic
lash adjusters.
CAUTION:
Install all parts in their original positions.
9. Select a suitable shim when replacing any of the following
parts with a new one: Cylinder head, shim, rocker arm guide
and valve seat. Proceed as follows to select the shim of cor-
rect thickness.
a. Install valve component parts to cylinder head (Except shim).
IAlways replace rocker arm guide with a new one.

Incident Simulation Tests
INTRODUCTION
Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the
conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The
following section illustrates ways to simulate the conditions/environment under which the owner experiences
an electrical incident.
The section is broken into the six following topics:
lVehicle vibration
lHeat sensitive
lFreezing
lWater intrusion
lElectrical load
lCold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of
the problem.
VEHICLE VIBRATION
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle
with A/C on). In such a case, you will want to check for a vibration related condition. Refer to the illustration
below.
Connectors & harness
Determine which connectors and wiring harness would affect the electrical system you are inspecting.Gently
shake each connector and harness while monitoring the system for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
Hint
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector ter-
minals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs
intermittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean
the terminals on related connectors in the system.
Sensors & relays
Gentlyapply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
SGI839 Vibration test
Shake gently.
Bend gently.Tap gently.
