3. INSPECT DRIVE BELTS
(a) Visually check the drive belt for cracks, oiliness or wear.
Check that the belt does not touch the bottom of the pulley
groove.
If necessary, replace the drive belts as a set.
(b) Using a belt tension gauge, measure the belt tension. Belt tension gauge:
Nippondenso BTG−20 (95506 −00020)
Borroughts No. BT−33−73F
Drive belt tension:
New belt400 − 580 N (41.0 − 59.1 kgf, 90.4 − 130.2 lbf)
Used belt200 − 390 N (20.4 − 40.0 kgf, 45.0 − 88.2 lbf)
If the belt tension is not as specified, adjust it.
HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.
4. VISUALLY CHECK GENERATOR WIRING AND LIS- TEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.
5. INSPECT DISCHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch ”ON”. Check that the discharge warning light comes on.
(b) Start the engine. Check that the light goes off.

CHARGING CHARGING SYSTEM
1996 LAND CRUISER (RM451U)
If the light does not operate as specified, troubleshoot the dis-
charge warning light circuit.
6. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as per the manufacturer’s instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:
Disconnect the wire from terminal B of the generator
and connect it to the negative ( −) lead of the amme-
ter.
Connect the positive (+) lead of the ammeter to ter-
minal B of the generator.
Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
Ground the negative ( −) lead of the voltmeter.
(b) Check the charging circuit as follows:
With the engine running from idle to 2,000 rpm, check the
reading on the ammeter and voltmeter.
Standard amperage 10 A or less
Standard voltage:
at 25° C ’(77°F)14.0 − 15.0 V
at 115°C ’(239° F)13.5 − 14.3 V
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than the standard voltage, check
the voltage regulator and generator as follows:
With terminal F grounded, start the engine and
check the voltmeter reading of terminal B.
If the voltmeter reading is more than standard volt-
age, replace the voltage regulator.
If the voltmeter reading is less than standard volt-
age, check the generator.
7. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at
”HI”.

DIAGNOSTICS ENGINE
1996 LAND CRUISER (RM451U)
6. BASIC INSPECTION
When the malfunction code is not confirmed in the DTC check, troubleshooting\
should be performed in the
order for all possible circuits to be considered as the causes of the problem\
s. In many cases, by carrying
out the basic engine check shown in the following flow chart, the location \
causing the problem can be found
quickly and efficiently. Therefore, use of this check is essential in engine troubleshooting.
1 Is battery positive voltage 11 V or more when engine is stopped?
NO Charge or replace battery.
YES
2 Is engine cranked?
NO Proceed to page ST−16 , and continue to trouble-
shoot.
YES
3 Does engine start?
NO Go to step 7.
YES
4 Check air filter.
PREPARATION:
Remove air filter.
CHECK:
Visually check that the air cleaner element is not dirty or exces-
sive oily.
HINT:
If necessary, clean the element with compressed air. First blow
from inside thoroughly, then blow from outside of element.
NG Repair or replace

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. DISCONNECT DISTRIBUTOR CONNECTOR
3. REMOVE SPARK PLUGS (See page IG−1 )
4. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible. Compression pressure:
1,176 kPa (12.0 kgf/cm
2, 171 psi) or more
Minimum pressure: 883 kPa (9.0 kgf/cm
2, 128 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
If the cylinder compression in one or more cylinders is low, pour
a small amount of engine oil into the cylinder through the spark
plug hole and repeat steps (a) through (c) for cylinders with low
compression.
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.
If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS (See page IG−1 )
6. RECONNECT DISTRIBUTOR CONNECTOR

SUPPLEMENTAL RESTRAINT SYSTEM SRS AIRBAG
1996 LAND CRUISER (RM451U)
OPERATION
1. STEERING WHEEL PAD (with AIRBAG)
The inflater and bag of the SRS are stored in the steering wheel
pad and cannot be disassembled. The inflater contains a squib,
igniter charge, gas generant, etc., and inflates the bag when
instructed by the airbag sensor assembly.
2. SPIRAL CABLE (in COMBINATION SWITCH)
A spiral cable is used as an electrical joint from the vehicle body
side to the steering wheel.
3. FRONT PASSENGER AIRBAG ASSEMBLY
The inflater and bag of the SRS are stored in the front passen-
ger airbag assembly and cannot be disassembled.The inflater
contains a squib, igniter charge, gas generant, etc., and inflates
the bag when instructed by the airbag sensor assembly.
4. SRS WARNING LIGHT
The SRS warning light is located on the combination meter. It
goes on to alert the driver of trouble in the system when a mal-
function is detected in the airbag sensor assembly. In normal
operating condition when the ignition switch is turned to the
ACC or ON position, the light goes on for about 6 seconds and
then goes off.
5. AIRBAG SENSOR ASSEMBLY
The airbag sensor assembly is mounted on the floor inside the
console box. The airbag sensor assembly consists of an airbag
sensor, safing sensor, diagnosis circuit and ignition control,
drive circuit, etc.
It receives signals from the airbag sensors and judges whether
the SRS must be activated or not.

(4) Connector Twin −Lock Mechanism
With this mechanism connectors (male and female
connectors) are locked by 2 locking devices to in-
crease connection reliability. If the primary lock is in-
complete, ribs interfere and prevent the secondary
lock.
(b) When the vehicle is involved in a frontal collision in the hatched area (Fig. 1) and the shock is larger than the pre-
determined level, the SRS is activated automatically. A
safing sensor is designed to go on at a smaller decelera-
tion rate than the airbag sensor. As illustrated in Fig. 2,
ignition is caused when current flows to the squib, which
happens when a safing sensor and the airbag sensor go
on simultaneously.When a deceleration force acts on the
sensors, two squibs in the driver airbag and front passen-
ger airbag ignite and generate gas. The gas discharging
into the driver airbag and front passenger airbag rapidly
increases the pressure inside the bags, breaking open
the steering wheel pad and instrument panel door.
Bag inflation then ends, and the bags deflate as the gas
is discharged through discharge holes at the bag’s rear or
side.
