GENERAL MAINTENANCE
These are maintenance and inspection items which are considered to be the owner’s responsibility.
They can be done by the owner or they can have them done at a service shop.
These items include those which should be checked on a daily basis, those which, in most cases, do not
require (special) tools and those which are considered to be reasonable for the owner to do.
Items and procedures for general maintenance are as follows.
1. GENERAL NOTES
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 performed.
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 interval (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 increase exhaust emissions.
2. LIGHTS
(a) Check that the headlights, stop lights, taillights, turn signal lights, and other lights are all working.
(b) Check the headlight aim.
3. WARNING LIGHTS AND BUZZERS
Check that all warning lights and buzzers function properly.
4. HORN
Check that it is working.
5. WINDSHIELD GLASS
Check for scratches, pits or abrasions.
6. WINDSHIELD WIPER AND WASHER
(a) Check operation of the wipers and washer.
(b) Check that the wipers do not streak.
7. WINDSHIELD DEFROSTER
Check that air comes out from the defroster outlet when operating the heater or air conditioner.
8. REAR VIEW MIRROR
Check that it is mounted securely.
9. SUN VISORS
Check that they move freely and are mounted securely.
10. STEERING WHEEL
Check that it has the specified freeplay. Be alert for changes in steering condition, such as hard steering,
excessive freeplay or strange noises.
11. SEATS
(a) Check that the seat adjusters operate smoothly.
(b) Check that all latches lock securely in any position.
(c) Check that the head restraints move up and down smoothly and that the locks hold securely in any
latch position.
(d) For fold−down seat backs, check that the latches lock securely.
12. SEAT BELTS
(a) Check that the seat belt system such as the buckles, retractors and anchors operate properly and
smoothly.
(b) Check that the belt webbing is not cut, frayed, worn or damaged.

Lubricate propeller shaft, referring to the lubrication chart. Be-
fore pumping in grease, wipe off any mud and dust on the
grease fitting.

INSPECTION PROCEDURE
1 Check vehicle speed value or resistance between terminals SP2 and E1 of ECM.
When using OBD II scan tool or TOYOTA hand−held tester:
PREPARATION:

ter to the DLC3.
(b) Start the engine and OBD II scan tool or TOYOTA hand−
held tester main switch ON.
CHECK:
Drive the vehicle and read vehicle speed value.
OK:
Vehicle speed matches tester speed value.
When not using OBD II scan tool or TOYOTA hand−held tes-
ter:
PREPARATION:
(a) Disconnect the connector from the ECM.
(b) Shift the shift lever to N position.
(c) Jack up the rear wheels on one side.
CHECK:
Check that there is continuity between terminals SP2 and E1
of ECM while slowly turning the jacked−up wheel by hand.
OK:

DTC 31 − 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 15 sec.
2. Momentary interruption of speed sensor signal occurs at
least 7 times in time between switching the ignition
switch ON and switching it OFF.
3. Abnormal fluctuation of speed sensor signals with ve-
hicle speed 20 km/h (12 mph) or more.
4. An open is detected in speed sensor circuit for 0.6 sec.

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.

− BRAKEFRONT BRAKE PAD (4WD)
BR−25
1996 TOYOTA T100 (RM449U)
REPLACEMENT
1. REMOVE FRONT WHEEL
2. INSPECT PAD LINING THICKNESS
Check the pad thickness and replace pads if not within specifi-
cation.
Minimum thickness: 1.0 mm (0.039 in.)
3. REMOVE THESE PARTS:
Clip
2 pins
Anti−rattle spring
2 pads
4 anti−squeal shims
NOTICE:
The anti−rattle spring can be used again provided that they
have sufficient rebound, no deformation, cracks or wear,
and have had all rust, dirt and foreign particles cleaned off.
4. CHECK DISC THICKNESS AND RUNOUT
(See page BR−36)

NOTICE:
When replacing worn pads, the anti−squeal shims must be
replaced together with the pads.
(a) Draw out a small amount of brake fluid from the reservoir.
(b) Press in the pistons with a hammer handle or equivalent.
HINT:
Always change the pad on one wheel at a time as there
is a possibility of the opposite piston flying out.
If the piston is difficult to push in, loosen the bleeder plug
and push in the piston while letting some brake fluid es-
cape.
(c) Install the 4 anti−squeal shims to new pads.
HINT:
Apply disc brake grease to the inner anti−squeal shims (See
page BR−24).
