BODY ELECTRICAL SYSTEM
PRECAUTION
Take care to observe the following precautions when performing inspections o\
r removal and replacement
of body electrical related parts.
1. HEADLIGHT SYSTEM
Halogen bulbs have pressurized gas inside and require special handling. They ca\
n burst if scratched or
dropped. Hold a bulb only by its plastic or metal case. Don’t touch the glass\
part of a bulb with bare hands.
2. SRS (SUPPLEMENTAL RESTRAINT SYSTEM)
The LAND CRUISER is equipped with an SRS (Supplemental Restraint System) such as the driver airbag
and front passenger airbag. Failure to carry out service operation in th\
e correct sequence could cause the
SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (in\
-
cluding removal or installation of parts, inspection or replacement), be sure t\
o read the precautionary notices
in the RS section.
3. AUDIO SYSTEM
If the negative (−) terminal cable is disconnected from the battery, the preset AM, FM 1 and FM 2 stations
stored in memory are erased, so be sure to note the stations and reset them af\
ter the negative ( −) terminal
cable is reconnected to the battery.
4. MOBILE COMMUNICATION SYSTEM
If the vehicle is equipped with a mobile communication system, refer to \
precautions in the IN section.

INSPECTION
1. INSPECT SPEEDOMETER ON−VEHICLE:
Using a speedometer tester, inspect the speedometer for allow-
able indication error and check the operation of the odometer.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.
If error is excessive, replace the speedometer.
Standard indicationAllowable range
2018 − 24
4038 − 44
6058 − 66
8078 − 88
10098 − 11 0
120118 − 132
2. INSPECT NO.1 VEHICLE SPEED SENSOR OPERA-
TION
(a) Connect the positive (+) lead from battery to terminal 1 and negative ( −) lead to terminal 2.
(b) Connect the positive (+) lead from tester to terminal 3 and
the negative ( −) lead to terminal 2.
(c) Revolve shaft.
(d) Check that there is voltage changer from approx. 0 V to 11 V or more between terminals 3 and 2.
HINT:
The voltage change should be 4 times per each revolution of
the No.1 vehicle speed sensor shaft.
If operation is not as specified, replace the sensor.
3. INSPECT TACHOMETER ON−VEHICLE:
(a) Connect a tune− up test tachometer, and start the engine.
NOTICE:
Reversing the connection of the tachometer will damage
the transistors and diodes inside.When removing or instal-
ling the tachometer, be careful not to drop or subject it to
heavy shocks.
(b) Compare the tester and tachometer indications.
If error is excessive, replace the tachometer.
