4. ERASURE OF TRANSPONDER KEY CODE
There are 2 ways for erasure of transponder key code, one is depressing brake pedal and acceleration pedal
and the other is using TOYOTA hand±held tester.
NOTICE:
All other master and sub±key codes are deleted leaving the master key code to use the operation.
When using the key which was used before deleting, it is necessary to register the code again.
HINT:

When any operation time described below is over, registration mode completes.

When the next procedure is performed while the timer is working, the timer completes counting time,
then next timer starts.
(1) Depressing brake pedal and acceleration pedal:

PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Description

When troubleshooting OBD II vehicles, the only dif-
ference from the usual troubleshooting procedure
is that you connect to the vehicle the OBD II scan
tool complying with SAE J1978 or TOYOTA hand±
held tester, and read off various data output from
the vehicle's ECM.

OBD II regulations require that the vehicle's on±
board computer lights up the Malfunction Indicator
Lamp (MIL) on the instrument panel when the com-
puter detects a malfunction in the emission control
system / components or in the powertrain control
components which affect vehicle emissions, or a
malfunction in the computer. In addition to the MIL
lighting up when a malfunction is detected, the ap-
plicable Diagnostic Trouble Code (DTC) prescribed
by SAE J2012 are recorded in the ECM memory.
(See page DI±16)
If the malfunction does not reoccur in 3 consecutive trips, the
MIL goes off automarially but the DTCs remain recorded in the
ECM memory.

To check the DTCs, connect the OBD II scan tool or
TOYOTA hand±held tester to Data Link Connector
3 (DLC3) on the vehicle. The OBD II scan tool or
TOYOTA hand±held tester also enables you to
erase the DTCs and check freezed frame data and
various forms of engine data (For operating instruc-
tions, see the OBD II scan tool's instruction book.)
DTCs include SAE controlled codes and manufac-
turer controlled codes. SAE controlled codes must
be set as prescribed by the SAE, while manufactur-
er controlled codes can be set freely by the
manufacturer within the prescribed limits. (See DTC
chart on page DI±16)

(2) Connect the OBD II scan tool or TOYOTA hand±
held tester to DLC3 under the instrument panel low-
er pad.
(3) Turn the ignition switch ON and turn 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 DTCs and freezed frame data
and note them down. (For operating instructions,
see the OBD II scan tool's instruction book.)
(5) See page DI±3 to confirm the details of the DTCs.
NOTICE:

When simulating symptoms with an OBD II scan tool
(excluding TOYOTA hand±held tester) to check the
DTCs, use normal mode. For code on the DTC chart
subject to º2 trip detection logicº, perform the follow-
ing either action.

Turn the ignition switch OFF after the symptom is
simulated the first time. Then repeat the simulation
process again. When the problem has been simulated
twice, the MIL lights up and the DTCs are recorded in
the ECM.

Check the 1st trip DTC using Mode 7 (Continuous Test
Results) for SAE J1979.
(c) Clear the DTC.
The DTCs and freezed frame data will be erased by either
action.
(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 ignition
switch is turned from ON to ACC or OFF during check
mode, the DTCs and freezed frame data will be erased.

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 page DI±3).
(2) Set the check mode (See page DI±3).
(3) Perform a simulation test (See page IN±21).
(4) Check the connector and terminal (See page IN±31).
(5) Handle the connector (See page IN±31).
6. BASIC INSPECTION
When the malfunction code is not confirmed in the DTC check, troubleshooting should be performed in the
order for all possible circuits to be considered as the causes of the problems. In many cases, by carrying
out the basic engine check shown in the following flow chart, the location causing the problem can be found
quickly and efficiently. Therefore, use of this check is essential in engine troubleshooting.

HINT:

If DTC P0105 (Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction) and P0106 (Man-
ifold Absolute Pressure /Barometric Pressure Circuit Range/Performance Problem) are output simul-
taneously, manifold absolute pressure sensor circuit may be open. Perform troubleshooting of DTC
P0105 first.

If DTC P0105 (Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction), P0106 (Manifold
Absolute Pressure /Barometric Pressure Circuit Range/Performance Problem), P0110 (Intake Air
Temp. Circuit Malfunction), P0115 (Engine Coolant Temp. Circuit Malfunction) and P0120 (Throttle/
Pedal Position Sensor/Switch ºAº Circuit Malfunction) are output simultaneously, E2 (sensor ground)
may be open.

Read freeze frame data using TOYOTA hand±held tester or OBD II scan tool. Because freeze frame
records the engine conditions when the malfunction is detected, when troubleshooting it is useful for
determining whether the vehicle was running or stopped, the engine warmed up or not, the air±fuel
ratio lean or rich, etc. at the time of the malfunction.

2 Connect OBD II scan tool or TOYOTA hand±held tester, and read value for volt-
age output of A/F sensor.
PREPARATION:
(a) Connect the OBD II scan tool or TOYOTA hand±held tester to the DLC3.
(b) Warm up the A/F sensor with the engine at 2,500 rpm for approx. 90 sec.
CHECK:
Read voltage value of the A/F sensor on the screen of OBD II scan tool or TOYOTA hand±held tester when
you perform all the following conditions.
HINT:
The voltage of AF
terminal of ECM is 3.3 V fixed and the A/F terminal is 3.0 V fixed. Therefore, it is impos-
sible to check the A/F sensor output voltage at the terminals (AF
/AF) of ECM.
OK:

speed 40 km/h (25 mph) or more, and operate throttle valve
open and close
Not remains at 3.8 V (* 0.76 V) or more

Not remains at 2.8 V (* 0.56 V) or less
*: When you use the OBD II scan tool (excluding TOYOTA hand±held tester)
HINT:

During fuel enrichment, there is a case that the output voltage of the A/F sensor is below 2.8 V (* 0.56
V), it is normal.

During fuel cut, there is a case that the output voltage of the A/F sensor is above 3.8 V (* 0.76 V), it
is normal.

If output voltage of the A/F sensor remains at 3.30 V (* 0.660 V) even after performing all the above
conditions, A/F the sensor circuit may be open.

If output voltage of A/F sensor remains at 3.8 V (* 0.76 V) or more, or 2.8 V (* 0.56 V) or less even after
performing all the above conditions, A/F sensor circuit may be short.
