1. Shift Lock Mechanism
When the brake pedal is depressed with the ignition SW is turned on (Stop light SW on), the shift lock control ECU is
activated and allows the driver to change the shift lever to a position other than P position.
2. Key Interlock Mechanism
When the ignition SW is turned on and the shift lever is at a position other than P position, shift lock control ECU is activated
to flow current to the key interlock solenoid. This inhibits to turn the ignition SW from on to OFF position.

2. FOR VEHICLE EQUIPPED WITH VEHICLE SKID CON-
TROL (VSC) SYSTEM
(a) Precaution when using drum tester:
When using a drum tester, make sure that the ignition
switch is OFF, start the engine with the diagnosis connec-
tor short-circuited between Ts and E
1 (CG) and take a
measurement.
NOTICE:
Check that VSC warning light is blinking.
Ensure that the vehicle does not move using wires.
After the measurement, disconnect the short circuit
and check that the VSC warning light is turned off
when restarting the engine.
(b) Precaution during VSC operation:
(1) Since VSC may be affected by the removal/installa-
tion of the VSC-related parts, do not remove/install
those parts unless absolutely necessary.
(2) When operating on VSC, follow the instructions in
BR section in this manual to surely make prepara-
tions or check after operations.
3. WHEN SERVICING FULL-TIME 4WD VEHICLES
The Full-time 4WD LAND CRUISER is equipped with the me-
chanical lock type center differential system.
During tests using a brake tester or chassis dynamometer, such
as braking force tests or speedometer tests, if only the front or
rear wheels are to be rotated, it is necessary to set the position
of the center differential to FREE or LOCK depending on the
type of the test being performed.

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.

(b) Using Braking Tester:
Measure by low-speed type (Vehicle Speed: Below 0.5
km/h or 0.3 mph) brake tester and observe the following
instructions before performing the test.
(1) Position the wheels to be tested (front or rear) on
the tester.
(2) Put the center differential in FREE position.
(3) If the vehicle is equipped with Vehicle Skid Control
(VSC) system, prohibit the system from the activa-
tion (See step 2.).
(4) Shift the transmission shift lever to ºNº position.
HINT:
Do not forget to change the Vehicle Skid Control (VSC) & Trac-
tion Control (TRAC) system to operational condition after the
test. Check that the VSC warning indicator light goes off when
restarting the engine.
(c) Using Speedometer Tester:
Observe the following instructions and then measure with
the rear wheels.
(1) Position the rear wheels on the tester roller.
(2) Position the front wheels on the free roller or jack
them up.
(3) Put the center differential in FREE position.
(4) If the vehicle is equipped with Vehicle Skid Control
(VSC) & Traction Control (TRAC) system, prohibit
the system from the activation (See step 2.).
(5) Ensure that the vehicle does not move using wires.
CAUTION:
The maximum speed should be less than 60 km/h (37 mph)
and maximum driving time should be 1 minute.
HINT:
Sudden shifting, braking, acceleration or deceleration is
not allowed.
Do not forget to change the Vehicle Skid Control (VSC) &
Traction Control (TRAC) system to operational condition
after the test. Check that the VSC warning indicator light
goes off when restarting the engine.

(d) Using Chassis Dynamometer:
Observe the following instructions and then measure with
the rear wheels.
(1) Remove the front propeller shaft.
(2) Put the center differential in LOCK position.
(3) If the vehicle is equipped with Vehicle Skid Control
(VSC) & Traction Control (TRAC) system, prohibit
the system from the activation (See step 2.).
(4) Ensure that the vehicle is securely fixed.
HINT:
Sudden shifting, braking, acceleration or deceleration is
not allowed.
Do not forget to change the Vehicle Skid Control (VSC) &
Traction Control (TRAC) system to operational condition
after the test. Check that the VSC warning indicator light
goes off when restarting the engine.
(e) On-V ehicle Wheel Balancing:
When doing on-vehicle wheel balancing on a full-time
4WD vehicle, to prevent each wheel from being rotated at
different speed in different directions (which could dam-
age the center differential), always be sure to observe the
following precautions.
(1) All of 4 wheels should be jacked up, being apart
from the ground completely.
(2) Put the center differential in LOCK position.
(3) If the vehicle is equipped with Vehicle Skid Control
(VSC) & Traction Control (TRAC) system, prohibit
the system from the activation (See step 2.).
(4) The parking brake lever should be fully released.
(5) None of the brakes should be applied.
(6) The wheels should be driven on the wheel balancer
with the engine running.
(7) Carry out the wheel balancing with the transmission
position in D position.
HINT:
When doing this balancing, pay attention to the other
wheels rotating at the same time.
Sudden acceleration, deceleration or braking is not al-
lowed.
Do not forget to change the Vehicle Skid Control (VSC) &
Traction Control (TRAC) system to operational condition
after the test. Check that the VSC warning indicator light
goes off when restarting the engine.
