0B-20 MAINTENANCE AND LUBRICATION
ENGINE START
Check engine start for readiness.
On automatic transmission vehicles, try to start the engine in each select lever position. The starting motor
should crank only in “P” (Park) or “N” (Neutral).
On manual transmission vehicles, place the shift lever in “Neutral,” depress clutch pedal fully any try to start.
EXHAUST SYSTEM CHECK
Check for leakage, cracks or loose supports.
CLUTCH (FOR MANUAL TRANSMISSION)
Check for the following.
Clutch is completely released when depressing clutch pedal,
No slipping clutch occurs when releasing pedal and accelerating.
Clutch itself is free from any abnormal condition.
GEARSHIFT OR SELECT LEVER (TRANSMISSION)
Check gear shift or select lever for smooth shifting to all positions and for good performance of transmission in
any position.
With automatic transmission equipped vehicle, also check that shift indicator indicates properly according to
which position select lever is shifted to.
With automatic transmission equipped vehicle, make sure that vehicle is at complete stop when shifting select
lever to “P” range position and release all brakes.
BRAKE
Foot Brake
Check the followings:
that brake pedal has proper travel,
that brake works properly,
that it is free from noise,
that vehicle does not pull to one side when brake is applied.
and that brake do not drag.
Parking Brake
Check that lever has proper travel.
Check to ensure that parking brake is fully effective when the vehicle is stopped on the safe slope and brake
lever is pulled all the way.WARNING:
Before performing the following check, be sure to have enough room around the vehicle. Then, firmly
apply both the parking brake and the regular brakes. Do not use the accelerator pedal. If the engine
starts, be ready to turn off the ignition promptly. Take these precautions because the vehicle could
move without warning and possibly cause personal injury or property damage.
WARNING:
With vehicle parked on a fairly steep slope, make sure nothing is in the way downhill to avoid any per-
sonal injury or property damage. Be prepared to apply regular brake quickly even if vehicle should
start to move.

1B-20 AIR CONDITIONING (OPTIONAL)
REFRIGERANT RECOVERY, EVACUATING AND CHARGING
OPERATION PROCEDURE FOR REFRIGERANT CHARGING
WARNING:
 Your eyes should not be exposed to refrigerant (liquid).
Any liquid HFC-134a (R-134a) escaping by accident shows a temperature as low as approximately
–6°C (32°F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a
serious injury. To protect your eyes against such accident, it is necessary to always wear goggles.
Should it occur that HFC-134a (R-134a) strikes your eyes, consult a doctor immediately.
– Do not use your hand to rub the affected eye(s). Instead, use quantities of fresh cold water to
splash it over the affected area to gradually raise temperature of such area above freezing point.
– Obtain proper treatment as soon as possible from a doctor or eye specialist.
 Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.
 Refrigerant must not be handled near where welding or steam cleaning is performed.
 Refrigerant should be kept at a cold and dark place. It should never be stored where a high temper-
ature is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle (including
trunk room).
 Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazard-
ous to health.

1B-24 AIR CONDITIONING (OPTIONAL)
CHARGING
CHARGING PROCEDURE
The initial charging of the A/C system is performed from the high
pressure side with the engine stopped.
And next, this method must be followed by charging from the low
pressure side with the engine running.
1) Check to make sure that hoses are routed properly after
evacuating the system.
2) Connect Low charging hose (1) and High charging hose (2)
of the manifold gauge set (3) in position. Thus open refriger-
ant container valve (4) to purge the charging line.
3) Open the high pressure side valve (5) and charge refrigerant
to system.
4) After a while, open the low pressure side valve (6) and close
the high pressure side valve (5).
5) Start engine and keep engine speed at 1500 r/min. Then,
operate air conditioning.
6) Charge A/C system with refrigerant in vapor state. At this
time, refrigerant container (4) should be held upright. CAUTION:
 Always charge through low pressure side of A/C system at after the initial charging is performed
from the high pressure side with the engine stopped.
 Never charge to high pressure side of A/C system with engine running.
 Do not charge while compressor is hot.
 When installing tap valve to refrigerant container to make a hole there through, carefully follow
directions given by manufacturer.
 A pressure gauge should always be used before and during charging.
 The refrigerant container should be emptied of refrigerant when discarding it.
 The refrigerant container should not be heated up to 40°C (104°F) or over.
 Refrigerant container should not be reversed in direction during charging. Reversing in direction
causes liquid refrigerant to enter compressor, causing troubles, such as compression of liquid
refrigerant and the like.
NOTE:
The air conditioning system contains HFC-134a (R-134a).
Described here is a method to charge the air conditioning system with refrigerant from the refrigerant
service container.
When charging refrigerant recovered by using the refrigerant and recycling equipment (when recy-
cling refrigerant), follow the procedure described in the equipment manufacturer’s instruction man-
ual.
WARNING:
Make sure that high pressure side valve is closed
securely.

3B1-4 ELECTRICAL POWER STEERING (P/S) SYSTEM
DIAGNOSIS
The P/S system in this vehicle is controlled by P/S control module. P/S control module has an on-board diagnos-
tic system which detects a malfunction in this system.
When diagnosing troubles, be sure to have full understanding of the outline of “ON-BOARD DIAGNOSTIC SYS-
TEM” and each item in “PRECAUTION IN DIAGNOSING TROUBLE” and execute diagnosis according to “SYS-
TEM CHECK FLOW TABLE”.
ON-BOARD DIAGNOSTIC SYSTEM
P/S control module performs on-board diagnosis (self-diagnosis)
on the system and operates “EPS” warning lamp (1) (malfunction
indicator lamp) as follows.
Malfunction indicator lamp (“EPS” warning lamp) lights when
the ignition switch is turned to ON position (but the engine at
stop) regardless of the condition of P/S control system. This
is only to check the malfunction indicator lamp (“EPS” warn-
ing lamp) bulb and its circuit.
If the areas monitored by P/S control module is free from any
trouble after the engine start (while engine is running), mal-
function indicator lamp (“EPS” warning lamp) turns OFF.
When P/S control module detects a trouble which has
occurred in the areas it monitors, malfunction indicator lamp
(“EPS” warning lamp) turns ON while the engine is running
to warn the driver of such occurrence of trouble and at the
same time it stores the exact trouble area in memory inside
of P/S control module.
PRECAUTIONS IN DIAGNOSING TROUBLES
Take a note of DTC indicated first.
Be sure to read “PRECAUTIONS FOR ELECTRONIC CIRCUIT SERVICE” in Section 0A before inspection
and observe what is written there.
When two or more troubles have occurred, their DTCs are indicated 3 times each starting with the smallest
code number and up.
DTC C1122 (DTC No.22) (engine speed signal failure) is indicated when ignition switch is ON position and
engine is not running but if indication changes to a normal one when engine is started, it means nothing
abnormal.
As DTC is stored in memory of P/S control module, be sure to clear memory after repair by performing the
procedure described in “DTC CLEARANCE”.

Parking brake stroke (When lever is pulled up at 200 N (20
kg, 44 lbs)
: 4 to 9 notches
BOOSTER OPERATION INSPECTION
There are two ways to perform this inspection, with and without a
tester. Ordinarily, it is possible to roughly determine its condition
without using a tester.
CHECK AIR TIGHTNESS
1) Start engine.
2) Stop engine after running for 1 to 2 minutes.
3) Depress brake pedal several times with the same load as in
ordinary braking and observe pedal travel. If pedal goes
down deep the first time but its travel decreases as it is
depressed the second and more times, air tightness is
obtained.
4) If pedal travel doesn’t change, air tightness isn’t obtained.
CHECK OPERATION
1) With engine stopped, depress brake pedal several times
with the same load and make sure that pedal travel doesn’t
change. NOTE:
For this check, make sure that no air is in hydraulic line.
1. 1st
2. 2nd
3. 3rd
NOTE:
If defective, inspect vacuum lines and sealing parts, and
replace any faulty part.When this has been done, repeat
the entire test.
1. 1st, 2nd, 3rd

5-12 BRAKES
2) Start engine while depressing brake pedal. If pedal travel
increases a little, operation is satisfactory. But no change in
pedal travel indicates malfunction.
CHECK AIR TIGHTNESS UNDER LOAD
1) With engine running, depress brake pedal. Then stop engine
while holding brake pedal depressed.
2) Hold brake pedal depressed for 30 seconds. If pedal height
does not change, condition is good. But it isn’t if pedal rises.
FLUID PRESSURE TEST (IF EQUIPPED WITH
LSPV)
Test procedure for LSPV assembly is as follows.
Before testing, confirm the following.
Fuel tank is filled with fuel fully.
Vehicle is equipped with spare tire, tools, jack and jack han-
dle.

6-6 ENGINE GENERAL INFORMATION AND DIAGNOSIS
FUEL PRESSURE RELIEF PROCEDURE
After making sure that engine is cold, release fuel pressure as fol-
lows.
1) Place transmission gear shift lever in “Neutral” (Shift selector
lever to “P” range for A/T model), set parking brake, and
block drive wheels.
2) Remove relay box cover.
3) Disconnect fuel pump relay (1) from relay box.
4) Remove fuel filler cap to release fuel vapor pressure in fuel
tank and then reinstall it.
5) Start engine and run it till it stops for lack of fuel. Repeat
cranking engine 2-3 times for about 3 seconds each time to
dissipate fuel pressure in lines. Fuel connections are now
safe for servicing.
6) Upon completion of servicing, connect fuel pump relay (1) to
relay box and install relay box cover.
FUEL LEAKAGE CHECK PROCEDURE
After performing any service on fuel system, check to make sure
that there are no fuel leakages as follows.
1) Turn ON ignition switch for 3 seconds (to operate fuel pump)
and then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply fuel pres-
sure to fuel line. (till fuel pressure is felt by hand placed on
fuel feed hose.)
2) In this state, check to see that there are no fuel leakages
from any part of fuel system.
ENGINE DIAGNOSIS
GENERAL DESCRIPTION
This vehicle is equipped with an engine and emission control system which are under control of ECM.
The engine and emission control system in this vehicle are controlled by ECM. ECM has an On-Board Diagnos-
tic system which detects a malfunction in this system and abnormality of those parts that influence the engine
exhaust emission. When diagnosing engine troubles, be sure to have full understanding of the outline of “On-
Board Diagnostic System” and each item in “Precaution in Diagnosing Trouble” and execute diagnosis accord-
ing to “ENGINE DIAGNOSTIC FLOW TABLE”.
There is a close relationship between the engine mechanical, engine cooling system, ignition system, exhaust
system, etc. and the engine and emission control system in their structure and operation. In case of an engine
trouble, even when the malfunction indicator lamp (MIL) doesn’t turn ON, it should be diagnosed according to
this flow table.CAUTION:
This work must not be done when engine is hot. If done
so, it may cause adverse effect to catalyst.
