REPLACEMENT
REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
See step 2. (a) above.
(b) Drain the coolant from the radiator drain cock and engine drain plug (Engine drain plug at the left of engine block.).
(c) Close the drain plugs. Torque:Torque (Engine drain plug):
29 N·m (300 kgf·cm, 22 ft·lbf)
(d) Slowly fill the system with coolant.
Use a good brand of ethylene −glycol base coolant
and mix it according to the manufacturer’s direc-
tions.
Using coolant which includes more than 50 % ethyl-
ene−glycol (but not more than 70 %) is recom-
mended.
NOTICE:
Do not use an alcohol type coolant.The coolant should be
mixed with demineralized water or distilled water. Capacity:
w/ Front heater:
13.7 liters (14.4 US qts, 12.1 lmp. qts)
w/ Front and rear heaters:
14.7 liters (15.5 US qts, 12.9 lmp. qts)
(e) Reinstall the radiator cap.
(f) Warm up the engine and check for leaks.
(g) Recheck the coolant level and refill as necessary.

2 Check No. 2 vehicle speed sensor.
PREPARATION:
Remove the No. 2 vehicle speed sensor from the transmission.
CHECK:
(a) Measure the resistance between terminals 1 and 2 of the

end of the vehicle speed sensor then taken away quickly.
OK:
(a) Resistance: 560 − 680 Ω
(b) Voltage is generated intermittently.
HINT:
The generated voltage is extremely low.
NG Replace No. 2 vehicle speed sensor.
OK

DTC31, 32, 33, 34, 35, 36 Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the ap-
propriate signals to the ECU. These signals are used to control
the ABS system. The front and rear rotors each have 48 serra-
tions.
When the rotors rotate, the magnetic field emitted by the perma-
nent magnet in the speed sensor generates an AC voltage.
Since the frequency of this AC voltage changes in direct propor-
tion to the speed of the rotor, the frequency is used by the ECU
to detect the speed of each wheel.
DTC No.DTC Detecting ConditionTrouble Area
31, 32, 33, 34
Detection of any of conditions (1) through (3):
(1) At vehicle speed of 10 km/h (6 mph) or more, pulses are
not input for 5 sec.
(2) Momentary interruption of the speed sensor signal oc-
curs at least 7 times in the time between switching the igni-
tion switch ON and switching it OFF.
(3) Abnormal fluctuation of speed sensor signals with the
vehicle speed 20 km/h (12 mph) or more.

Speed sensor signal is not input for about 1 sec. while
the right front and left rear speed sensor signals are being
checked with the IG switch ON.

HINT:

DTC No. 31 is for the right front speed sensor.

DTC No. 32 is for the left front speed sensor.

DTC No. 33 is for the right rear speed sensor.

DTC No. 34 is for the left rear speed sensor.
Fail safe function:
If trouble occurs in the speed sensor circuit, the ECU cuts off current to the ABS control (solenoid) relay and
prohibits ABS control.

UNDER HOOD
GENERAL MAINTENANCE
1. GENERAL NOTICE
Maintenance items may vary from country to country. Check the owner’s manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performe\
d.
Periodic maintenance service must be performed according to whichever interval in\
the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time inter\
val (months).
Maintenance service after the last period should be performed at the same interval \
as before unless
otherwise noted.
Failure to do even one item can cause the engine to run poorly and incre\
ase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL Check that the coolant level is between the FULL and LOW lines on the se\
e −through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leave\
s, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells is between the upp\
er and lower level lines on the case.
If level is low, add distilled water only.
6. BRAKE FLUID LEVELS
Check that the brake fluid level is near the upper level line on the see\
−through reservoir.
7. ENGINE DRIVE BELTS
Check drive belt for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL
(a) Check the level on the dipstick.
(b) The level should be in the HOT or COLD range depending on the fluid temp\
erature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking and foot brake applied, shift the sel\
ector into all positions from the P to L, and then shift into the P.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re −insert the dipstick fully and check that
the fluid level is in the HOT range.
(d) Do this check with the fluid at normal driving temperature (70 − 80°C (158 − 176° F)).
HINT:
Wait about 30 minutes before checking the fluid level after extended driving\
at high speeds in hot weather,
driving in heavy traffic or with a trailer.
11. EXHAUST SYSTEM
Visually inspect for cracks, holes or loose supports.
If any change in the sound of the exhaust or smell of the exhaust fumes is\
noticed, have the cause located
and corrected.
