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.

(10) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clear the DTC.
The following actions will erase the DTCs and freezed
frame data.
(1) Operating the OBD II scan tool (complying with SAE
J1978) or TOYOTA hand−held tester to erase the
codes. (See the OBD II scan tool’ s instruction book
for operating instructions.)
(2) Disconnecting the battery terminals or EFI fuse.
NOTICE:
If the TOYOTA hand −held tester switches the ECM from
normal mode to check mode or vice −versa, or if the igni-
tion switch is turned from ON to ACC or LOCK during check
mode, the DTCs and freezed frame data will be erased.
4. FAIL−SAFE CHART
If any of the following codes is recorded, the ECM enters fail −safe mode.
DTC No.Fail−Safe OperationFail− Safe Deactivation Conditions
P0100Ignition timing fixed at 5 ° BTDC
 Injection method fixed at simultaneous injectionReturned to normal condition
P0110Intake air temp. is fixed at 20° C (68°F)Returned to normal condition
P0115Engine coolant temp. is fixed at 80 °(176°F)Returned to normal condition
P0120VTA is fixed at 0°
The following condition must be repeated at least 2 times
consecutively
When closed throttle position switch is ON:
0.1 V  VTA  0.95 V
P0135
P0141The heater circuit in witch an abnormality is detected is
turned offIgnition switch OFF
P0325
P0330Max. timing retardationIgnition switch OFF
P1300Fuel cutIGF signal is detected for 6 consective ignitions
P1605Max. timing retardationReturned to normal condition
5. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA hand−held tester only:
By putting the vehicle’s ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic
and sensitivity to detect open circuits is increased. This makes it easier \
to detect intermittent problems.
(1) Clear the DTC (See step 2).
(2) Set the check mode (See step 3).
(3) Perform a simulation test (See page IN−18).
(4) Check the connector and terminal (See page IN−28).
(5) Handle the connector (See page IN−28).
(6) Visual check and contact pressure (See page IN−28).

(4) Use the OBD II scan tool or TOYOTA hand−held
tester to check the DTCs and freeze frame data.
Note them down (For operating instructions, see
the OBD II scan tool’s instruction book).
(5) See page DI−143 to confirm the details of the
DTCs.
NOTICE:
When simulating symptoms with an OBD II scan tool (ex-
cluding TOYOTA hand −held tester) to check the DTCs, use
the normal mode. For codes on the DTC chart subject to ”2
trip detection logic”, turn the ignition switch off after the
symptoms have been simulated for the 1st time. Them re-
peat the simulation process again. When the program has
been simulated twice, the MIL lights up and the DTCs are
recorded in the ECM.
3. Check Mode: INSPECT DIAGNOSIS
HINT:
TOYOTA hand−held tester only:
Compared to the normal mode, the check mode has high sens-
ing ability to detect malfunctions. Furthermore, the same diag-
nostic items which are detected in the normal mode can also be
detected in check mode.
(a) Check the DTC. (1) Check the initial conditions.
Battery positive voltage 11 V or more.
Throttle valve fully closed.
Transmission in P position.
Air conditioning switched off.
(2) Turn the ignition switch OFF.
(3) Prepare the TOYOTA hand−held tester.
(4) Connect the TOYOTA hand− held tester to the
DLC3 in the fuse box at the lower left of the instru-
ment panel.
(5) Turn the ignition switch ON and switch the T OYOTA
hand −held tester ON.
(6) Switch the TOYOTA hand −held tester from the nor-
mal mode to the check mode (Check that the MIL
flashes).
(7) Start the engine (The MIL goes).
(8) Simulate the conditions of the malfunction de- scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTCs etc.
