(a) Place the vehicle in the following conditions.

The area around the headlight is not deformed.

The vehicle is parked on a level surface.

Tire inflation pressure is the specified value.

A driver is in the driver's seat and the vehicle is in a state ready for driving (with a tank full).

The vehicle has been bounced several times.
(b) Check the headlight aiming.
(1) Prepare a thick white paper.
(2) Stand the paper perpendicular to the ground at the position 9.84 ft away from the headlights.
(3) Ensure that the center line of the vehicle and the paper face forms a 90±degree angle as shown
in the illustration.
(4) Draw a horizontal line (H line) on the paper, showing where the headlights should strike.
(5) Draw a vertical line (V line) to where the center line of the vehicle is to be.
(6) Draw 2 vertical lines to where the the headlights should strike (V RH and V LH lines).
(7) Draw a horizontal line (by connecting the both low beam center marks) to where the headlights
should strike (H RH and H LH lines).
HINT:
The H RH and H LH line is 0.4° below the horizontal line (H line) of the light axis.
(8) Start the engine.

(9) Turn the headlights ON.
(10) Check that the headlights properly strike the position shown in the illustration.
(11) If not, adjust the lights in the vertical direction.
HINT:

As shown in the illustration, adjust each aim of the RH and LH lights.

The value of the ºHigh Beamº aim is a reference value. Since the horizontal direction is impossible to
adjust, the value * of the ºLow Beamº aim is also a reference value.
(c) When adjusting it in the vertical direction:
Using adjusting bolt (vertical direction), adjust the headlight aim to within the specified range.

NOTICE:
ºColdº and ºHotº in these sentences express the temperature of the coils themselves. ºColdº is from

1. INSPECT SPARK TEST
Check that the spark occurs.
(1) Disconnect the high±tension cord from the spark plug.
(2) Remove the spark plug.
(3) Install the spark plug to the high±tension cord.
(4) Ground the spark plug.
(5) See if spark occurs while engine is being cranked.
NOTICE:
To prevent gasoline from being injected from injectors during this test, crank the engine for no more
than 5 ± 10 seconds at time.
If the spark does not occur, do the test as follows:

2. INSPECT HIGH±TENSION CORDS
(a) Remove the high±tension cords.
Disconnect the high±tension cords at the rubber boot. Do
not pull on the high±tension cords.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.
(b) Using an ohmmeter, measure the high±tension cord re-
sistance.
Maximum resistance: 25 kW per cord
If the resistance is greater than maximum, check the terminals.
If necessary, replace the high±tension cord.
(c) Reinstall the high±tension cords.
3. INSPECT SPARK PLUGS
NOTICE:

Never use a wire brush for cleaning.

Never attempt to adjust the electrode gap on a used
spark plug.

Spark plugs should be replaced every 100,000 km
(60,000 miles).
(a) Disconnect the high±tension cords from the spark plugs.
(b) Inspect the electrode.
Using a megger (insulation resistance meter), measure
the insulation resistance.
Standard correct insulation resistance:
10 MW or more
If the resistance is less than specified, proceed to step (d).
HINT:
If a megger is not available, the following simple method of in-
spection provides fairly accurate results.
Simple Method:

Quickly race the engine to 4,000 rpm 5 times.

Remove the spark plug. (See step (c))

Visually check the spark plug.
If the electrode is dry ... OK
If the electrode is wet ... Proceed to step (d)

Reinstall the spark plug. (See step (g))

(c) Using a 16 mm plug wrench, remove the 4 spark plugs.
(d) Visually check the spark plug for thread damage and insu-
lator damage.
If abnormal, replace the spark plug.
Recommended spark plug:

NGK madeBKR6EKPB11
(e) Inspect the electrode gaps.
Maximum electrode gap for used spark plug:
1.3 mm (0.051 in.)
If the gap is greater than maximum, replace the spark plug.
Correct electrode gap for new spark plug:
1.1 mm (0.043 in.)
NOTICE:
If adjusting the gap of a new spark plug, bend only the base
of the ground electrode. Do not touch the tip. Never attempt
to adjust the gap on the used plug.
(f) Clean the spark plugs.
If the electrode has traces of wet carbon, allow it to dry and then
clean with a spark plug cleaner.
Air pressure: Below 588 kPa (6 kgf/cm
2, 85 psi)
Duration: 20 seconds or less
HINT:
If there are traces of oil, remove it with gasoline before using the
spark plug cleaner.
(g) Using a 16 mm plug wrench, install the 4 spark plugs.
Torque: 18 N´m (180 kgf´cm, 13 ft´lbf)
(h) Reconnect the high±tension cords from the spark plugs.
4. INSPECT IGNITION COILS WITH IGNITERS
(a) Disconnect the high±tension cords from the ignition coils.
(b) Inspect the secondary coil resistance.
Using an ohmmeter, measure the resistance between the
high±tension terminals.
Secondary coil resistance:
Cold9.7 ± 16.7 kW
Hot12.4 ± 19.6 kW
