TOYOTA hand-held tester only:
When the diagnosis system is switched from the nor-
mal mode to the check mode, it erases all DTC and
freezed frame data recorded in the normal mode. So
before switching modes, always check the DTC 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 the DLC3 at the lower center of the
instrument panel.
(3) Turn the ignition switch ON and push 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 and
note them down (For operating instructions, see the
OBD II scan tool's instruction book.).
If there is no DTC in the normal mode, check the 1st
trip DTC using Continuous Test Results function
(Mode 7 for SAE J1979) on the OBD II scan tool or
TOYOTA hand-held tester.
(5) See page DI-14 to confirm the details of the DTC.
NOTICE:

When simulating symptoms with an OBD II scan tool
(excluding TOYOTA hand-held tester) to check the
DTC, use the 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 1st 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.

Operating the OBD II scan tool (complying
with SAE J1978) or TOYOTA hand-held tes-
ter to erase the codes. (See the OBD II scan
tool's instruction book for operating instruc-
tions.)

NOTICE:
If the TOYOTA hand-held tester switches the ECM from the
normal mode to the check mode or vice-versa, or if the
ignition switch is turned from ON to ACC or OFF during the
check mode, the DTCs and freezed frame data will be
erased.
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.
Check the DTC.
(1) Initial conditions.

Battery positive voltage 11 V or more

Throttle valve fully closed

Transmission in P or N position

A/C 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 at the lower center of the instrument panel.
(5) Turn the ignition switch ON and push the TOYOTA
hand-held tester switch ON.
(6) Switch the TOYOTA hand-held tester from the nor-
mal mode to the check mode (Check that the MIL
flashes.).
NOTICE:
If the TOYOTA hand-held tester switches the ECM from the
normal mode to the check mode or vice-versa, or if the
ignition switch is turned from ON to ACC or OFF during the
check mode, the DTC and freezed frame data will be
erased.
(7) Start the engine (The MIL goes out after the engine
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 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 the check
mode to the normal mode, so all DTC, etc. are erased.
(10) After checking the DTC, inspect the applicable cir-
cuit.
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

5. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA hand-held tester only:
By putting the vehicle's ECM in the 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-20).
(4) Check the connector and terminal (See page IN-30).
(5) Handle the connector (See page IN-30).
6. BASIC INSPECTION
When the malfunction code is not confirmed in the DTC check, troubleshooting should be performed in order
for all possible circuits to be considered as the cause 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.
1 Is battery positive voltage 11 V or more when engine is stopped?
NO Charge or replace battery.
YES
2 Is engine cranked?

2. INSPECT DIAGNOSIS (Normal Mode)
(a) Check the DTC using hand-held tester.
NOTICE:
Hand- held tester only: When the diagnosis system 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 hand-held tester.
(2) Connect the hand-held tester to DLC3.
(3) Turn the ignition switch ON and push the hand-held
tester main switch ON.
(4) Use the hand-held tester to check the DTCs and
freezed frame data, note them down. (For operating
instructions, see the hand-held tester instruction
book.)
(5) See page DI-601 to confirm the details of the DTCs.
(b) Clear the DTC.
The following operations will erase the DTCs and freeze
frame data.
(1) Operating the OBD ll scam tool (complying with
SAEJ1978) or hand-held tester to erase the codes.
(See the OBD ll scan tool's instruction book for op-
erating instructions.)
(2) Disconnecting the battery terminals or EFI fuse.
