(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN−8).
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 place stoppers behind the rear wheels.
When jacking up the rear wheels of the vehicle at
first place stoppers before the front wheels.
When either the front or rear wheels only should be
jacked up, set rigid racks and place stoppers in front
and behind 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 small job that can be finished quickly.
(l) 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 elec- tronic components, air filter and emission −related
components from water.
(6) Never use an impact wrench to remove or install temperature switches or temperature sensors.

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.
SystemPage
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

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.
