REPAIR INSTRUCTIONS
GENERAL INFORMATION
BASIC REPAIR HINT
Use fender, seat and floor covers to keep the vehicle
clean and prevent damage.
During disassembly, keep parts in the appropriate order
to facilitate reassembly.
Observe the following operations
(1) Before performing electrical work, disconnect the
negative (-) terminal cable from the battery.
(2) Ifit is necessary to disconnect the battery for in-
spection or repair, always disconnect the negative
(-) terminal cable which is grounded to the vehicle
body.
(3) To prevent damage to the battery terminal, loosen
the cable nut and raise the cable straight up without
twisting or prying it
(4) Clean the battery terminals and cable ends with a
clean shop rag. Do not scrape them with a file or oth-
er abrasive objects.
(5) _ install the cable ends to the battery terminals with
the nut loose, and tighten the nut after installation.
Do not use a hammer to tap the cable ends onto the
terminals.
(6) Be sure the cover for the positive (+) terminal is
properly in place.
Check hose and wiring connectors to make sure that they
are secure and correct.
Non-reusable parts
(1) Always replace cotter pins, gaskets, O-rings and oil
seals etc. with new ones.
(2) Non-reusable parts are indicated in the component
illustrations by the "@" symbol.
Precoated paris
Precoated parts are bolts and nuts, etc. that are coated
with a seal lock adhesive at the factory.
(1) If a precoated part is retightened, loosened or
caused to move in any way, it must be recoated with
the specified adhesive.
(2) When reusing precoated parts, clean off the old
adhesive and dry with compressed air. Then apply
the specified seal lock adhesive to the bolt, nut or
threads,
(3) Precoated parts are indicated in the component i
lustrations by the "*” symbol
When necessary, use a sealer on gaskets to prevent
leaks.INS
INTRODUCTION — REPAIR INSTRUCTIONS
(h) Carefully observe all specifications for bolt tightening
torques. Always use a torque wrench.
(i) Use of special service tools (SST) and special service ma-
terials (SSM) may be required, depending on the nature
of the repair. Be sure to use SST and SSM where speci-
fied and follow the proper work procedure. A list of SST
and SSM can be found in section PP (Preparation) in this ce
manual
i) When replacing fuses, be sure the new fuse has the cor-
rect amperage rating. DO NOT exceed the rating or use
one with a lower rating

(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lit and support the vehicle at the prop-
er locations.
+ Cancel the parking brake on the level place and
shift the transmission in Neutral (or N position).
+ When jacking up the front wheels of the vehicle at
first piace stoppers behind the rear wheels.
+ When jacking up the rear wheels of the vehicle at
first place stoppers behind the rear wheels.IN-6
INTRODUCTION —_ REPAIR INSTRUCTIONS.
+ When either the front or rear wheels only should be
set rigid racks and place stoppers in front
the other wheels on the ground.
+ After the vehicle is jacked up, be sure to support it
on rigid racks. It is extremely dangerous to do any
work on a vehicle raised on a jack alone, even for
a smail job that can be finished quickly.
(i) Observe the following precautions to avoid damage to the
following parts:
(1) Do not open the cover or case of the ECU unless
absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static electric-
ity)
(2) To disconnect vacuum hoses, pull off the end, not
the middle of the hose.
(3) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(4) Be careful not to drop electrical components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not reused.
(5) When steam cleaning an engine, protect the eleo-
| tronic components, air filter and emission-related
‘components from water.
eats (6) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(7) When checking continuity at the wire connector, in-
sert the tester probe carefully to prevent terminals
from bending.
(8) When using a vacuum gauge, never force the hose
onto a connector that is too large. Use a step-down
adapter for adjustment. Once the hose has been
stretched, it may leak.INT
INTRODUCTION —_REPAIR INSTRUCTIONS.
(m) Tag hoses before disconnecting them:
(1) When disconnecting vacuum hoses, use tags to
identity how they should be reconnected.
(2) After completing a job, double check that the vacu-
um hoses are properly connected. A label under the
hood shows the proper layout.
(n) Unless otherwise stated, all resistance is measured at an
ambient temperature af 20°C (68°F). Because the resis-
tance may be outside specifications if measured at high
temperatures immediately after the vehicle has been run-
ning, measurement should be made when the enging has
cooled down.IN-8
WWMROQUGTION FOR ALL OF VEHIGLE
FOR ALL OF VEHICLES
PRECAUTION
1, FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION:
if large amount of unburned gasoline flows into the converter, it may overheat and create a fire haz-
ard. To prevent this, observe the following precautions and explain them to your customer.
(a) _ Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.
(c)_ Avoid spark jump test.
(1) Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine.
(a) Avoid prolonged engine compression measurement.
Engine compression tests must be done as rapidly as possible.
(@) Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra load on the converter.
(f) Avoid coasting with ignition turned off and prolonged braking
(9) Do not dispose of used catalyst along with parts contaminated with gasoline or oil.
2. IF VEHICLE IS EQUIPPED WITH MOBILE COMMUNICATION SYSTEM
For vehicles with mobile communication systems such as two-way radios and cellular telephones, observe
the following precautions.
(1) Install the antenna as far as possible away fram the ECU and sensors of the vehicle's electronic
system.
(2) _ Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the ve-
hicle’s electronic systems. For details about ECU and sensors locations, refer to the section on
the applicable component.
(3) Avoid winding the antenna feeder together with the other wiring as much as possible, and also
avoid running the antenna feeder parallel with other wire harnesses.
(4) Check that the antenna and feeder are correctly adjusted.
(5) Do not install powerful mobile communications system.
3. FOR USING HAND-HELD TESTER
CAUTION:
Observe the following items for safety reasons:
+ Before using the hand-held tester, the hand-held tester’s operator manual should be read
throughly.
+ Be sure to route all cables securely when driving with the hand-held tester connected to the
vehicte. (i.e. Keep cables away from feet, pedals, steering wheel and shift lever.)
+ Two persons are required when test driving with the hand-held tester, one person to drive the
vehicle and one person to operate the hand-held tester.INTRODUCTION — HOW 1. TROUBLESHOOT ECU CONTROLLED Ine

HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
GENERAL INFORMATION
A large numbers of ECU cantrolled systems are used in the LAND CRUISER/LAND CRUISER PRADO. In
general, the ECU controlled system is considered to be a very intricate system Cequiring a high level of techni-
cal knowiedge and expert skill to troubleshoot. However, the fact is that if you proceed to inspect the circuits
one by one, troubleshooting of these systems is not complex. If you have adequate understanding of the
system and a basic knowledge of electricity, accurate diagnosis and necessary repair can be performed to
Jocate and fix the problem. This manual is designed through emphasis of the above standpoint to help ser-
vice technicians perform accurate and etfective troubleshaating, and is compiled for the following major ECU
controlled systems:
System Page
Engine Dia
The troubleshooting procedure and how to make use of it are described on the above pages.
FOR USING HAND-HELD TESTER
+ Before using the hand-held tester, the hand held-tester’s operator manual should be read throughly.
+ Ifthe hand-held tester cannot communicate with ECU controlled systems when you have connected
the cable of the hand-held tester to DLCS, turned the ignition switch ON and operated the scan tool,
there is a problem on the vehicle side or too! side.
(1) If communication is normal when the taal is connected to another vehicle, inspect the diagnosis
data link line (Bus@line) or ECU power circuit of the vehicle,
(2) communication is still not possible when the tool is connected to another vehicle, the problem
is probably in the fool itself, so pertorm the Seif Test procedures outlined in the Tester Operator's

1. CUSTOMER PROBLEM ANALYSIS
In troubleshooting, the problem symptoms must be confirmed accurately and all preconceptions must be
cleared away in order to give an accurate judgement. To ascertain just what the problem symptoms are, it
is extremely important to ask the customer about the problem and the conditions at the time it occurred.
Important Point in the Problem Analysis:
The following 5 items are important points in the problem analysis. Past problems which are thought to be
unrelated and the repair history, etc. may also help in some cases, so as much information as possible should
be gathered and its relationship with the problem symptoms should be correctly ascertained for reference
in troubleshooting. A customer problem analysis table is provided in the troubleshooting section for each
system for your use.

2. SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE CHECK
The diagnostic system in the LAND CRUISE/LAND CRUISER PRADO fulfills various functions. The first
function is the Diagnostic Trouble Code Check in which a malfunction in the signal circuits to the ECU is
stored in code in the ECU memory at the time of occurrence, to be output by the technician during trouble-
shooting. Another function is the Input Signal Check which checks if the signals from various switches are
sent to the ECU correctly.
By using these check functions, the problem areas can be narrowed down quickly and troubleshooting can
be performed effectively. Diagnostic functions are incorporated in the following systems in the LAND CRUIS-
ER/LAND CRUISER PRADO.

Engine | o °
(with Test Mode)
In diagnostic trouble code check, itis very important to determine whether the problem indicated by the diag-
nastic trouble code is still occurring or occurred in the past but returned to normal at present. In addition,
it must be checked in the problem symptom check whether the malfunction indicated by the diagnostic
trouble code is directly related to the problem symptom or not. For this reason, the diagnostic trouble codes
should be checked before and after the symptom confirmation to determine the current conditions, as shown
in the table below. If this is not done, it may, depending on the case, result in unnecessary troubleshooting
fot normally operating systems, thus making it more difficult to locate the problem, or in repairs not pertinent
to the problem. Therefore, always follow the procedure in correct order and perform the diagnostic trouble
code check.

3. SYMPTOM SIMULATION
The most difficult case in troubleshooting is when there are no problem symptoms occurring. In such cases,
a thorough customer problem analysis must be carried out, then simulate the same or similar conditions and
environment in which the problem occurred in the customer's vehicle. No matter haw much experience a
technician has, or how skilled he may be, if he proceeds to troubleshoot without confirming the problem
symptoms he will tend to overlook something important in the repair operation and make a wrong quess
somewhere, which will only lead to a standstil. For example, for a problem which only occurs when the en-
gine is cold, or for a problem which occurs due to vibration caused by the road during driving, etc., the prob-
lem can never be determined so long as the symptoms are confirmed with the engine hot condition or the
vehicle at a standstill. Since vibration, heat or water penetration (moisture) is likely cause for problem which
is difficult to reproduce, the symptom simulation tests introduced here are effective measures in that the ex-
ternal causes are applied to the vehicle in a stopped condition
important Points in the Symptom Simulation Test
Inthe symptom simulation test, the problem symptoms should of course be confirmed, but the problem area
or parts must also be found out. To de this, narrow down the possible problem circuits according to the symp-
toms before starting this test and connect a tester beforehand. After that, carry out the symptom simulation
test, judging whether the circuit being tested is defective or normal and also confirming the problem symp-
(oms at the same time. Refer to the problem symptoms table for each system to narrow down the possible
causes of the symptom.

HOW TO USE THE DIAGNOSTIC
CHART AND INSPECTION
PROCEDU RE
CONNECTOR CONNECTION AND TERMINAL IN-
SPECTION
+ For troubleshooting, diagnostic trouble code charts or
problem symptom charts are provided for each circuit with
detailed inspection procedures on the following pages.
+ When all the component parts, wire harnesses and con-
nectors of each circuit except the ECU are found to be
normal in troubleshooting, then it is determined that the
problem is in the ECU. Accordingly, if diagnosis is per-
formed without the problem symptoms occurring, refer to
step 8 to replace the ECU, even if the problem is notin the
ECU. So always confirm that the problem symptoms are
occurring, or proceed with inspection while using the
symptom simulation method
+ The instructions "Check wire harness and connector’ and
"Check and replace ECU" which appear in the inspection
procedure, are common and applicable to all diagnostic
trouble codes. Follow the procedure outlined below
whenever these instructions appear.
OPEN CIRCUIT:
This could be due to a disconnected wire harness, faulty con-
tact in the connector, and a connector terminal pulled out, etc.
HINT:
+ tis rarely the case that a wire is broken in the middle of
it, Most cases occur at the connector. In particular, care-
fully check the connectors of sensors and actuators.
+ Faulty contact could be due to rusting of the connector
terminals, to foreign materials entering terminals or a de-
formation of connector terminals. Simply disconnecting
and reconnecting the connectors once changes the
condition of the connection and may result in a return to
normal operation. Therefore, in troubleshooting, if no ab-
normality is found in the wire harness and connector
check, but the problem disappears after the check, then
the cause is considered to be in the wire harness or con-
rectors.
SHORT CIRCUIT:
This could be due to a contact between wire harness and the
body ground or to a short circuit occurred inside the switch, etc.
HINT:
When there isa short circuit between the wire harness and body
ground, check thoroughly whether the wire hares is caught
in the body or is clamped properly.INTRODUCTION ~ HOV To TROUBLESHOOT ECU CONTROLLED IN-2t

SYSTEMS,
2. CONTINUITY CHECK (OPEN CIRCUIT CHECK)
(a) Disconnect the connectors at both ECU and sensor
sides.
(b) Measure the resistance between the applicable terminals
of the connectors.
Resistance: 10 or less
. Measure the resistance while lightly shaking the wire hax-
ness vertically and horizontally.
+ When tester probes are inserted into a connector, insert
the probes from the back. For waterproof connectors in
which the probes cannot be inserted from the back, be
careful not to bend the terminals when inserting the tester
probes.
3. RESISTANCE CHECK (SHORT CIRCUIT CHECK)
(a) Disconnect the connectors on both ends.
(b) Measure the resistance between the applicable terminals
of the connectors and body ground. Be sure to carry out
this check on the connectors on both ends.
Resistance: 1 MQ or higher
HINT:
‘Measure the resistance while lightly shaking the wire harness
vertically and horizontally.
4, VISUAL CHECK AND CONTACT PRESSURE CHECK
(a) Disconnect the connectors at both ends.
(b) Check for rust or foreign material, etc. in the terminals of
the connectors.
(c) Check crimped portions for looseness or damage and
check that the terminals are secured in lock portion.
HINT:
The terminals should not come out when pulled lightly.
(d) Prepare a test male terminal and insert it in the female ter-
minal, then pull it out.
NOTICE:
When testing a gold-plated female terminal, always use a
gold-plated male terminal.
HINT:
When the test terminal is pulled out more easily than others,
there may be poor contact in that section.IN-22

5. CONNECTOR HANDLING
When inserting tester probes into a connector, insert them from
the rear of the connector. When necessary, use mini test leads.
For water resistant connectors which cannot be accessed from
behind, take good care not to deform the connector terminals.
6. CHECK OPEN CIRCUIT
For the open circuit in the wire hamess in Fig. 1, perform "(a)
Continuity Check” or "(b) Voltage Check’ to locate the section

of connector "C" -> No continuity (open)
Between terminal 2 of connector “A” and terminal 2
of connector "C" > Continuity
Therefore, it is found out that there is an open circuit,
between terminal 1 of connector "A” and terminal 4
of connector °C”
Disconnect connector "B" and measure the resis-
tance between the connectors.
In the case of Fig. 3,

(b) Check the voltage.
Ina circuit in which voltage is applied (to the ECU connec-
tor terminal), an open circuit can be checked for by con-
ducting a voltage check.
As shown in Fig. 4, witht each connector still connected,
measure the voltage between body ground and terminal
1 of connector “A” at the ECU SV output terminal, terminal
1 of connector "B", and terminal 1 of connector "C”, in that
order.
(Cthe results are:
5V: Between Terminal 1 of connector “A’ and Body Ground
5V: Between Terminal 1 of connector "B" and Body Ground
OV: Between Terminal 1 of connector "C* and Body Ground
Then it is found out that there is an open circuit in the wire hat-
ness between terminal 1 of "B” and terminal 1 of "C”
7. CHECK SHORT CIRCUIT
Ifthe wire hamessis ground shorted as in Fig. 5, locate the sec-
tion by conducting a “continuity check with ground”.
Check the continuity with ground,
(1) Disconnect connectors “A” and °C” and measure
the resistance between terminal 1 and 2 of connec-
tor "A" and body ground.
In the case of Fig. 6
Between terminal 1 of connector
ground > Continuity (short)
Between terminal 2 of connector "A" and body
ground -» No continuity
Therefore, it is found out that there is a short circuit
between terminal 1 of connector “A” and terminal 1
of connector "C

Disconnect connector "B" and measure the resis-
tance between terminal 1 of connector "A" and body
ground, and terminal 1 of connector "B2" and body
ground.
Between terminal 1 of connector "A" and body
ground > No continuity
Between terminal 1 of connector "B2" and body
ground > Continuity (short)
‘Therefore, itis found out that there is a short circuit
between terminal 1 of connector "B2" and terminal
1 of connector °C"
8. CHECK AND REPLACE ECU
First check the ECU ground circuit. Ifit is faulty, repair it If itis
normal, the ECU could be faulty, so replace the ECU with a nor-
mal functioning one and check that the symptoms appear.
