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.

AUDIO SYSTEM
DESCRIPTION
1. RADIO WAVE BAND
The radio wave bands used in radio broadcasting are as follows:
LF: Low Frequency
MF: Medium Frequency
HF: High Frequency
VHF: Very High Frequency
2. SERVICE AREA
There are great dif ferences in the size of the service area for AM
and FM monaural. Sometimes FM stereo broadcasts cannot be
received even through AM can be received in very clearly.
Not only does FM stereo have the smallest service area, but it
also picks up static and other types of interference (”noise”)
easily.
3. RECEPTION PROBLEMS
Besides the problem of static, there are also the problems
called ”fading”, ”multipath” and ”fade out”. These problems \
are
caused not by electrical noise but by the nature of the radio
waves themselves.
(1) FadingBesides electrical interference, AM broadcasts are
also susceptible to other types of interference, es-
pecially at night. This is because AM radio waves
bounce off the ionosphere at night. These radio
waves then interfere with the signals from the same
transmitter that reach the vehicle’ s antenna directly.
This type of interference is called ”fading”.

(2) Multipath
One type of interference caused by the bounce of
radio waves off of obstructions is called ”multipath”.
Multipath occurs when a signal from the broadcast
transmitter antenna bounces off buildings and
mountains and interferes with the signal that is re-
ceived directly.
(3) Fade Out Because FM radio waves are of higher frequencies
than AM radio waves, they bounce off buildings,
mountains, and other obstructions. For this reason,
FM signals often seem to gradually disappear or
fade away as the vehicle goes behind a building or
other obstruction. This is called ”fade out”.
4. COMPACT DISC PLAYER
Compact Disc (hereafter called ”CD”) Players use a laser beam
pick−up to read the digital signals recorded on the CD and re-
produce analog signals of the music, etc. There are 4.7 in. (12
cm) and 3.2 in. (8 cm) discs in the CD player.
HINT:
Never attempt to disassemble or oil any part of the player unit.
Do not insert any object other than a disc into the magazine.
NOTICE:
CD players use an invisible laser beam which could cause
hazardous radiation exposure. Be sure to operate the play-
er correctly as instructed.
5. Tape Player/Head Cleaning: MAINTENANCE
(a) Raise the cassette door with your finger.
Next, using a pencil or similar object, push in the guide.
(b) Using a clean ing pen or cotton applicator soaked in clean-
er, clean the head surface, pinch rollers and capstans.

HINT:
If your display shows ”UNABLE TO CONNECT TO VEHICLE”
when you have connected the cable of the OBD II scan tool or
TOYOTA hand−held tester to DLC3, turned the ignition switch
ON and operated the scan tool, there is a problem on the ve-
hicle side or tool side.
If communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.
If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool’s instruction manual.
2. INSPECT DIAGNOSIS (NORMAL MODE)
(a) Check the MIL. (1) The MIL comes on when the ignition switch is turnedON and the engine is not running.
HINT:
If the MIL does not light up, troubleshoot the combination meter
(See page BE−2 ).
(2) When the engine started, the MIL should go off. If the lamp remains on, the diagnosis system has de-
tected a malfunction or abnormality in the system
(b) Check the DTC.
NOTICE:
TOYOTA hand−held tester only: When the diagnosis sys-
tem is switched from normal mode to check mode, it
erases all DTCs and freezed frame data recorded in normal
mode. So before switching modes, always check the DTCs
and freezed frame data, and note them down (1) Prepare the OBD II scan tool (complying with SAE
J 1978) or TOYOTA hand−held tester.
(2) Connect the OBD II scan tool or TOYOTA hand− held tester to DLC3 in the fuse box at the lower left
of the instrument panel.
(3) Turn the ignition switch ON and switch the OBD II
scan tool or TOYOTA hand −held tester switch ON.
(4) Use the OBD II scan tool or TOYOTA hand−held tester to check the DTC and freezed frame data,
note them down. (For operating instructions, see
the OBD II scan tool’s instruction book.)
(5) See page DI−13 to confirm the details of the
DTCs.

DIAGNOSTICS ENGINE
1996 LAND CRUISER (RM451U)
NOTICE:
When simulating symptoms with an OBD II scan tool (ex-
cluding TOYOTA hand −held tester) to check the DTC, use
normal mode. For codes on the DTC chart subject to ”2 trip
detection logic”, turn the ignition switch OFF after the
symptom is simulated the first time. Then repeat the simu-
lation process again. When the problem has been simu-
lated twice, the MIL lights up and the DTCs are recorded in
the ECM.
3. INSPECT DIAGNOSIS (CHECK MODE)
HINT:
TOYOTA hand−held tester only:
Compared to the normal mode, the check mode has an in-
creased sensitivity to detect malfunctions.
Furthermore, the same diagnostic items which are detected in
the normal mode can also be detected in the check mode.
(a) Check the DTC. (1) Initial conditions
Battery positive voltage 11 V or more.
Throttle valve fully closed.
Transmission in ”park” or ”neutral” position.
Air conditioning switched OFF.
(2) Turn ignition switch OFF.
(3) Prepare the TOYOTA hand−held tester.
(4) Connect the TOYOTA hand−held tester to DLC3 in
the fuse box at the lower left of the instrument panel.
(5) Turn the ignition switch ON and push the TOYOTA hand−held tester ON.
(6) Switch the TOYOTA hand −held tester normal mode
to check mode (Check that the MIL flashes.).
(7) Switch the engine (The MIL goes out after the en- gine start.).
(8) Simulate the conditions of the malfunction de- scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTC, etc. (9) After simulating the malfunction conditions, use theTOYOTA hand−held tester diagnosis selector to
check the DTCs and freezed frame data, etc.
HINT:
Take care not to turn the ignition switch OFF. T urning the ignition
switch OFF switches the diagnosis system from check mode to
normal mode, so all DTCs, etc. are erased.
