Transfer gear ºHº e ºLº gear shifting procedure:
When shifting, always put the shift lever of the transmis-
sion in N position. In other positions, the gears of the
transfer clash, and switching cannot be performed.
4. WHEN TESTING BRAKES, SPEEDOMETER, ETC.
(a) When carrying out any kind of servicing or testing on a
Full-time 4WD in which the front or rear wheels are to be
rotated (braking test, speedometer test), be sure to ob-
serve the precautions given below.
Incorrect preparations or test procedures may cause dan-
ger as well as unsuccessful test results.
Before starting any such servicing or test, be sure to
check the following items:
Center differential mode position (FREE or LOCK)
Vehicle skid control (VSC) system (with or without):
If the vehicle is equipped with the system, the slip
indicator light, the VSC/TRAC indicator light and the
VSC OFF indicator light come on with the ignition
key turned to ºONº. They will go off after about a few
seconds.
Whether wheels should be touching ground or
jacked up
Transmission gear position (N position)
Transfer gear position (H or L position)
Maximum testing vehicle speed
Maximum testing time
HINT:
w/o Vehicle skid control (VSC) system:
When the transfer select lever is put in ºLº position, the center
differential is put in LOCK condition regardless of the position
of the center differential lock switch.

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 judgment. 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 Diagnostics section for each system
for your use.

2. SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE CHECK
The diagnostic system in the LAND CRUISER 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 troubleshooting. 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.

In diagnostic trouble code check, it is very important to determine whether 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 current 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 and perform the diagnostic trouble
code check.
