− DIAGNOSTICSENGINE
1996 RAV4 (RM447U)
NOTICE:
When simulating symptoms with an OBDII 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 DTC 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 at
the lower of the instrument panel.
(5) Turn the ignition switch ON and push the TOYOTA
hand−held tester main switch ON.
(6) Switch the TOYOTA hand−held tester normal mode
to check mode. (Check that the MIL flashes.)
(7) Start the engine. (The MIL goes out after the engine
starts.)
(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 the
TOYOTA hand−held tester diagnosis selector to
check the DTC and freezed frame data, etc.
HINT:
Take care not to turn the ignition switch OFF. Turning the ignition
switch OFF switches the diagnosis system from check mode to
normal mode, so all diagnostic codes, etc. are erased.

− DIAGNOSTICSENGINE
DI−7
1996 RAV4 (RM447U)
(10) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clear the DTC.
The following actions will erase the DTC and freezed
frame data.
(1) Operating the OBDII scan tool (complying with SAE
J1978) or TOYOTA hand−held tester to erase the
codes.
(See the OBDII scan tool’s instruction book for oper-
ating 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 it the ignition
switch is turned from ON to ACC or OFF during check
mode, the DTC and freezed frame data will be erased.
4. FAIL−SAFE CHART
If any of the following codes is recorded, the ECM enters fail−sate mode.
DTC No.Fail−Safe OperationFail−Safe Deactivation Conditions
P0105Ignition timing fixed at 5° BTDCReturned to normal condition
P0110Intake air temp. is fixed at 68°F (20°C)Returned to normal condition
P0115Engine coolant temp. is fixed at 176°F (80°C)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
P0325Max. timing retardationIgnition switch OFF
P1300Fuel cutIGF signal is detected for 1 ignition
5. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA hand−held tester only:
By putting the vehicle’s ECM in check mode, 1 trip detection logic possible instead of 2 trip detection logic
and sensitivity to detect open circuit is increased. This makes it easier to detect intermittent problems.
(1) Clear the diagnostic trouble codes (See page DI−3)
(2) Set the check mode (See page DI−3)
(3) Perform a simulation test (See page IN−20)
(4) Check the connector and terminal inspection (See page IN−30)
(5) Visual check and contact pressure (See page IN−30)
(6) Handle the connector (See page IN−30)
