REPAIR INSTRUCTIONS
GENERAL INFORMATION
BASIC REPAIR HINT
(a) Use fender, seat and floor covers to keep the vehicle
clean and prevent damage.
(b) During disassembly, keep parts in the appropriate order to facilitate reassembly.
(c) Installation and removal of battery terminal: (1) Before performing electrical work, disconnect the
negative (−) terminal cable from the battery.
(2) If it is necessary to disconnect the battery for in- spection or repair, first disconnect the negative ( −)
terminal cable.
(3) When disconnecting the terminal cable, to prevent damage to 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 after loosening the nut, and tighten the nut after installa-
tion. 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.
(d) Check hose and wiring connectors to make sure that they
are connected securely and correctly.
(e) Non−reusable parts (1) Always replace cotter pins, gaskets, O−rings, oilseals, etc. with new ones.
(2) Non−reusable parts are indicated in the component illustrations by the ” ” symbol.
(f) Precoated parts Precoated parts are bolts, nuts, etc. that are coated with
a seal lock adhesive at the factory.
(1) If a precoated part is retightened, loosened orcaused 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.

FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER
(a) The LAND CRUISER is equipped with an SRS (Supple-
mental Restraint System), such as the driver airbag and
front passenger airbag assembly.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.
(b) GENERAL NOTICE (1) Malfunction symptoms of the supplemental re-straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting. When
troubleshooting the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the battery (See page DI−240).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the ”LOCK” posi-
tion and the negative ( −) terminal cable is discon-
nected from the battery.
(The supplemental restraint system is equipped
with a back−up power source so that if work is
started within 90 seconds of disconnecting the neg-
ative (−) terminal cable from the battery, the SRS
may deploy.)
When the negative (−) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled. So before starting
work, make a record of the contents memorized by
the each memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory sys-
tem, never use a back− up power supply from anoth-
er battery.

HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
GENERAL INFORMATION
A large number of ECU controlled systems are used in the LAND CRUISER. In general, the ECU controlled
system is considered to be a very intricate system requiring a high level of t\
echnical knowledge and expert
skill to troubleshoot. However, the fact is that if you proceed to inspect the circuits one by one, trou\
bleshoot-
ing of these systems is not complex. If you have adequate understanding of the system and a basic knowl-
edge of electricity, accurate diagnosis and necessary repair can be performed to locate and fix the pr\
oblem.
This manual is designed through emphasis of the above standpoint to help service techn\
icians perform ac-
curate and effective troubleshooting, and is compiled for the following major ECU con\
trolled systems:
The troubleshooting procedure and how to make use of it are described on\
the following pages.

1. EngineDI−1
2. Automatic TransmissionDI−129
3. Anti− Lock Brake SystemDI−188
4. Supplemental Restraint SystemDI−238
5. Cruise Control SystemDI−284
FOR USING OBD II SCAN TOOL OR TOYOTA HAND−HELD TESTER
Before using the scan tool or tester, the scan tool’ s instruction book or tester’s operator manual should
be read thoroughly.
If the scan tool or tester cannot communicate with ECU controlled systems \
when you have connected
the cable of the scan tool or tester to DLC3, turned the ignition switch\
ON and operated the scan tool,
there is a problem on the vehicle side or tool side.
(1) If communication is normal when the tool is connected to another vehicle, \
inspect the diagnosis data link line (Bus line) or ECU power circuit of the vehicle.
(2) If communication is still not possible when the tool is connected to anoth\
er vehicle, the problem is probably in the tool itself, so perform the Self Test procedures outline in the Tester Operator’s
Manual.

2. SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE CHECK
The diagnostic system in the LAND CRUISER fulfills various functions. The first functio\
n is the Diagnostic
Trouble Code Check in which a malfunction in the signal circuits to the ECU is stored in co\
de in the ECU
memory at the time of occurrence, to be output by the technician during troubl\
eshooting. Another function
is the Input Signal Check which checks if the signals from various switc\
hes are sent to the ECU correctly.
By using these check functions, the problem areas can be narrowed down qui\
ckly and troubleshooting can
be performed ef fectively. Diagnostic functions are incorporated in the following systems in the LAND CRUIS-
ER.

2. Automatic T ransmission
(with Check Mode)
3. Anti− Lock Brake System
4. Supplemental Restraint System
5. Cruise Control System
In diagnostic trouble code check, it is very important to determine whethe\
r the problem indicated by the diag-
nostic 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 curre\
nt conditions, as shown
in the table below. If this is not done, it may, depending on the case, result in unnecessary troubleshooting
for 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 an\
d perform the diagnostic trouble
code check.

DTC P0325Knock Sensor 1 Circuit Malfunction
CIRCUIT DESCRIPTION
Knock sensor is fitted to the cylinder block to detect engine knocking. This sensor c\
ontains a piezoelectric element which
generates a voltage when it becomes deformed, which occurs when the cyli\
nder block vibrates due to knocking. If engine
knocking occurs, ignition timing is retarded to suppress it.
DTC No. DTC Detection Condition Trouble Area
