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.

DTC P0500 Vehicle Speed Sensor Malfunction
CIRCUIT DESCRIPTION
The vehicle speed sensor outputs a 4 − pulse signal for every revolution of the rotor shaft, which is rotated
by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectan-
gular wavefrom by the waveform shaping circuit inside the combination meter, it is then transmitted to the
ECM. The ECM determines the vehicle speed based on the frequency of thes\
e pulse signals.
