6) Replenish oil until oil level is brought to FULL level mark on
dipstick. (oil pan and oil filter capacity). The filler inlet is at
the top of the cylinder head cover.
It is recommended to use engine oil of SE, SF, SG, SH, SJ or
SL grade.
Select the appropriate oil viscosity according to the proper
engine oil viscosity chart [A].
Engine oil specification
7) Check oil filter and drain plug for oil leakage.
8) Start engine and run it for three minutes. Stop it and wait five
minutes before checking oil level. Add oil, as necessary, to
bring oil level to FULL level mark on dipstick.
Engine Coolant
CHANGE
Change engine coolant referring to “Cooling System Flush and
Refill” in Section 6B.
Exhaust System
INSPECTION
Oil pan capacity About 3.8 liters (8.0/6.7 US/lmp pt.)
Oil filter capacity About 0.2 liters (0.4/0.3 US/lmp pt.)
Others About 0.3 liters (0.6/0.5 US/lmp pt.)
Total About 4.3 liters (9.1/7.6 US/lmp pt.)
NOTE:
Engine oil capacity is specified. However, note that the
amount of oil required when actually changing oil may
somewhat differ from the data in the table depending on
various conditions (temperature, viscosity, etc.)
1. Full level mark (hole)
2. Low level mark (hole)
WARNING:
To avoid danger of being burned, do not touch exhaust
system when it is still hot. Any service on exhaust sys-
tem should be performed when it is cool.

5) To increase clearance between brake shoe and brake drum,
remove rubber plug from brake back plate and turn adjuster
downward with flat-head screw driver.
6) Remove brake drum (1) off by using 8 mm bolts (2).
INSPECTION
Brake Drum
Inspect drum for cleanliness. Check wear of its braking surface by
measuring its inside diameter.
Drum inner diameter “a”
Standard : 220 mm (8.66 in.)
Service Limit : 222 mm (8.74 in.)
Whenever brake drums are removed, they should be thoroughly
cleaned and inspected for cracks, scores, deep grooves.
Cracked, scored, or grooved drum
A cracked, drum is unsafe for further service and must be
replaced.
Do not attempt to weld a cracked drum.
Smooth up any slight scores. Heavy or extensive scoring will
cause excessive brake lining wear and it will probably be neces-
sary to resurface drum braking surface.
If brake linings are slightly worn and drum is grooved, drum
should be polished with fine emery cloth but should not be turned.
NOTE:
When drum is removed, visually inspect wheel cylinder
for brake fluid leakage. Correct leaky point, if any.

CLEARANCE BETWEEN BOOSTER PISTON ROD AND
MASTER CYLINDER PISTON
The length of booster piston rod (1) is adjusted to provide speci-
fied clearance “a” between piston rod end and master cylinder
piston (2).
Before measuring clearance, push piston rod several times
so as to make sure reaction disc is in place.
Keep inside of booster at atmospheric pressure for measure-
ment.
Remove piston (push) rod seal from booster, if equipped.
1) Set special tool (E) on master cylinder (1) and push pin (3)
until contacts piston (2).
Special tool
(E): 09950-96010
2) Turn special tool upside down and place it on booster (1).
Adjust booster piston rod (2) length until rod end contacts pin
head (3).
Special tool
(E): 09950-96010
Clearance “b” (between special tool and piston rod)
0 mm (0 in.)
3) Adjust clearance by turning adjusting screw of piston rod.
Special tool
(F) : 09952-16010
NOTE:
Take measurement with booster set vertically or piston
rod supported with screw driver or such so as to set rod
at the center.

THROTTLE POS (ABSOLUTE THROTTLE POSITION, %)
When throttle position sensor is fully closed position, throttle opening is indicated as 0% and 100% full open
position.
OXYGEN SENSOR B1 S1 (HEATED OXYGEN SENSOR-1, V)
It indicates output voltage of HO2S-1 installed on exhaust manifold (pre-catalyst).
OXYGEN SENSOR B1 S2 (HEATED OXYGEN SENSOR-2, V)
It indicates output voltage of HO2S-2 installed on exhaust pipe (post-catalyst). It is used to detect catalyst dete-
rioration.
DESIRED IDLE (DESIRED IDLE SPEED, rpm)
The Desired Idle Speed is an ECM internal parameter which indicates the ECM requested idle. If the engine is
not running, this number is not valid.
TP SENSOR VOLT (THROTTLE POSITION SENSOR OUTPUT VOLTAGE, V)
The Throttle Position Sensor reading provides throttle valve opening information in the form of voltage.
INJ PULSE WIDTH (FUEL INJECTION PULSE WIDTH, msec.)
This parameter indicates time of the injector drive (valve opening) pulse which is output from ECM (but injector
drive time of NO.1 cylinder for multiport fuel injection).
IAC FLOW DUTY (IDLE AIR (SPEED) CONTROL DUTY, %)
This parameter indicates current flow time rate within a certain set cycle of IAC valve (valve opening rate) which
controls the amount of bypass air (idle speed).
TOTAL FUEL TRIM (%)
The value of Total Fuel Trim is obtained by putting values of short Term Fuel Trim and Long Term Fuel Trim
together. This value indicates how much correction is necessary to keep the air / fuel mixture stoichiometrical.
BATTERY VOLTAGE (V)
This parameter indicates battery positive voltage inputted from main relay to ECM.
CANIST PURGE DUTY (EVAP CANISTER PURGE FLOW DUTY, %)
This parameter indicates valve ON (valve open) time rate within a certain set cycle of EVAP purge solenoid
valve which controls the amount of EVAP purge.
0% means that the purge valve is completely closed while 100% is a fully open valve.
CLOSED THROTTLE POSITION (ON / OFF)
This parameter will read ON when throttle valve is fully closed, or OFF when the throttle is not fully closed.
FUEL CUT (ON / OFF)
ON : Fuel being cut (output signal to injector is stopped)
OFF : Fuel not being cut
A/C CONDENSER FAN (A/C CONDENSER FAN RELAY, ON / OFF)
ON : Command for condenser fan relay operation being output.
OFF : Command for relay operation not being output.
