Switch positionTester connectionSpecified condition
Switch OFF7 − 10Continuity
Switch ON4 − 5 − 6 − 9
7 − 8Continuity
Illumination circuit2 − 3Continuity
If continuity is not as specified, replace the switch.
3. INSPECT TURN SIGNAL FLASHER OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (−) lead to terminal 3.
(b) Connect the 2 turn signal light bulbs parallel to each other
to terminals 1 and 3, check that the bulbs flash.
HINT:
The turn signal lights should flash 60 or 120 times per minute.
If one of the front or rear turn signal lights has an open circuit,
the number of flashing will be more than 140 per minute.
If operation is not as specified, replace the flasher.

HINT:
If your display shows ”UNABLE TO CONNECT TO VEHICLE”
when you have connected the cable of the OBDII 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 turned
ON and the engine is not running.
HINT:
If the MIL does not light up, troubleshoot the combination meter.
(2) When the engine is started, the MIL should go off.
If the lamp remains on,the diagnosis system has
detected a malfunction or abnormality in the sys-
tem.
(b) Check the DTC.
NOTICE:
TOYOTA hand−held tester only:
When the diagnosis system is switched from normal mode
to check mode, it erases all DTC and freezed frame data re-
corded in normal mode. So before switching modes, al-
ways check the DTC and freezed frame data, and note them
down.
(1) Prepare the OBDII scan tool (complying with SAE
J1978) or TOYOTA hand−held tester.
(2) Connect the OBDII scan tool or TOYOTA hand−
held tester to DLC3 at the lower of the instrument
panel.
(3) Turn the ignition switch ON and turn the OBDII scan
tool or TOYOTA hand−held tester switch ON.
(4) Use the OBDII scan tool or TOYOTA hand−held tes-
ter to check the DTC and freezed frame data, note
them down.
(5) See page DI−14 to confirm the details of the
DTC.

(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)

CIRCUIT DESCRIPTION
The EGR system recirculates exhaust gas, which is controlled to the proper quantity to suit the driving condi-
tions, into the intake air mixture to slow down combustion, reduce the combustion temperature and reduce
NOx emissions. The amount of EGR is regulated by the EGR vacuum modulator according to the engine
load.
If even one the following conditions is fulfilled, the VSV is turned
ON by a signal from ECM. This results in atmospheric air acting
on the EGR valve, closing the EGR valve and shutting off the
exhaust gas (EGR cut−off).
Before the engine is warmed up
During deceleration (throttle valve closed) .
Light engine load (amount of intake air very small).
Engine idling.
Engine speed over 4,400 rpm.
High engine load (amount of intake air very large)
