Diagnostic Information and Procedures
Compression CheckS6RW0D1404001
Check compression pressure on all 4 cylinders as
follows:
1) Warm up engine to normal operating temperature.
2) Stop engine after warming up.
NOTE
After warming up engine, place transmission
gear shift lever in “Neutral” (shift selector
lever to “P” range for A/T model), and set
parking brake and block drive wheels.

3) Remove air cleaner assembly with air suction hose
referring to “Air Cleaner Assembly Removal and
Installation”.
4) Remove cylinder head upper cover.
5) Remove ignition coil assemblies and all spark plugs
referring to “Spark Plug Removal and Installation in
Section 1H”.
6) Disconnect fuel injector wires at the coupler.7) Install special tools (Compression gauge) into spark
plug hole.

8) Disengage clutch (1) (to lighten starting load on
engine) for M/T vehicle, and depress accelerator
pedal (2) all the way to make throttle fully open.
9) Crank engine with fully charged battery, and read the
highest pressure on compression gauge.
NOTE
• For measuring compression pressure,
crank engine at least 250 r/min. by using
fully charged battery.
• If measured compression pressure is
lower than limit value, check installation
condition of special tool. If it is properly
installed, possibility is compression
pressure leakage from where piston ring
and valve contact.

Compression pressure
Standard: 1400 kPa (14.0 kgf/cm2, 199.0 psi)
Limit: 1100 kPa (11.0 kgf/cm2, 156.0 psi)
Max. difference between any two cylinders: 100
kPa (1.0 kgf/cm
2, 14.2 psi)
10) Carry out Steps 7) through 9) on each cylinder to
obtain 4 readings.
11) After checking, install spark plugs and ignition coil
assemblies with high-tension cord referring to “Spark
Plug Removal and Installation in Section 1H”.
12) Connect ignition coil couplers.
13) Connect fuel injector wires at the coupler.
14) Install cylinder head upper cover.
15) Install air cleaner assembly with air section hose
referring to “Air Cleaner Assembly Removal and
Installation”.
Engine Vacuum CheckS6RW0D1404002
The engine vacuum that develops in the intake line is a
good indicator of the condition of the engine. The
vacuum checking procedure is as follows:
1) Warm up engine to normal operating temperature.
NOTE
After warming up engine, place transmission
gear shift lever in “Neutral” (shift selector
lever to “P” range for A/T model), and set
parking brake and block drive wheels.

2) Stop engine and turn off the all electric switches.
3) Remove air cleaner assembly with air suction hose
referring to “Air Cleaner Assembly Removal and
Installation”.
4) Remove PCV hose (1) from PCV valve (2).
5) Connect special tool (Vacuum gauge) to PCV hose
(1).
Special tool
(A): 09915–67311
6) Blind PCV valve (2) using tape (3) or the like.I2RH0B140005-01

3) Ground “F” terminal and start engine, then measure
voltage at “B” terminal as shown in figure.
• Voltage is higher than standard value. It is
considered that generator itself is good but IC
regulator has been damaged, replace IC
regulator.
• Voltage is lower than standard value. It is
considered that generator itself has problem,
check the generator.
Load Check
1) Run engine at 2,000 rpm and turn on head light and
heater motor.
2) Measure current and if it is less than 20 A, repair or
replace generator.Generator Test (Overcharged Battery Check)S6RW0D1A04004
1) To determine battery condition, refer to “Battery
Description”.
2) If obvious overcharged condition exists as evidenced
by excessive spewing of electrolyte, measure
generator “B” terminal voltage at engine 2000 rpm.
3) If measured voltage is higher than upper limit value,
disassemble generator.
4) Check ground of brushes. If brushes are not
grounded, replace IC regulator. Then check field coil
for grounds and shorts.
Repair Instructions
Jump Starting in Case of EmergencyS6RW0D1A06001
With Auxiliary (Booster) Battery
CAUTION!
If vehicle is manual transaxle model and has
a catalytic converter, do not push or tow it to
start. Damage to its emission system and/or
to other parts may result.

Both booster and discharged battery should be treated
carefully when using jumper cables. Follow the
procedure outlined as follows, being careful not to cause
sparks.
WARNING!
• Departure from these conditions or
procedure described as follows could
result in:
– Serious personal injury (particularly to
eyes) or property damage from such
causes as battery explosion, battery
acid, or electrical burns.
– Damage to electronic components of
either vehicle.
• Remove rings, watches, and other jewelry.
Wear approved eye protection.
• Be careful so that metal tools or jumper
cables do not contact positive battery
terminal (or metal in contact with it) and
any other metal on vehicle, because a
short circuit could occur.
• Do not connect negative cable directly to
negative terminal of dead battery.

3) Install steering column upper cover (1) and lower
cover (2).
CAUTION!
When installing covers, be careful so that
each lead wire is not caught between covers.
Otherwise, each lead wire is damaged.

4) Install steering wheel to steering column. Refer to
“Steering Wheel Removal and Installation”.
5) Connect negative (–) cable to battery.
6) Enable air bag system referring to “Enabling Air Bag
System in Section 8B”.
Centering Contact Coil Cable AssemblyS6RW0D6206004
1) Check that vehicle’s wheels (front tires) are set at
straight-ahead position.
2) Check that ignition switch is at LOCK position.
3) Turn contact coil counterclockwise slowly with a light
force till contact coil will not turn any further.
NOTE
Contact coil can turn about 5 turns at the
maximum, that is, if it is at the center
position, can turn about two and a half turns
both clockwise and counterclockwise.

4) From the position where contact coil became unable
to turn any further (it stopped), turn it back clockwise
about two and a half rotations and align center mark
with alignment mark (1).
Contact Coil Cable Assembly InspectionS6RW0D6206005
Refer to “Contact Coil Cable and Its Circuit Check in
Section 8B”.
Steering Column Removal and InstallationS6RW0D6206008
CAUTION!
Once the steering column is removed from
the vehicle, the column is extremely
susceptible to damage.
• Dropping the column assembly on its end
could collapse the steering shaft or loosen
the plastic shear pins which maintain
column length.
• Leaning on the column assembly could
cause it to bend or deform.
Any of the damage could impair the column’s
collapsible design.
Steering column mounting nuts should not
be loosened with steering shaft joint upper
side bolt tightened as this could cause
damage to shaft joint bearing.

NOTE
When servicing steering column or any
column-mounted component, remove
steering wheel. But when removing steering
column simply to gain access to instrument
panel components, leave steering wheel
installed on steering column.
