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 an OBD II scan
tool complying with SAE J1987 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 computer itself or
in drive system components which affect vehicle
emissions. In addition to the MIL lighting up when
a malfunction is detected, the applicable DTCs pre-
scribed by SAE J2012 are recorded in the ECM
memory. (See page DI±211)
If the malfunction only occurs in 3 trips, the MIL goes
off but the DTCs remain recorded in the ECM
memory.

To check the DTCs, connect an OBD II scan tool or
TOYOTA hand±held tester to DLC3 on the vehicle.
The OBD II scan tool or TOYOTA hand±held tester
also enables you to erase the DTCs and check
freeze frame data and various forms of engine data
(For instruction book).
DTCs include SAE controlled codes and Manufac-
turer controlled codes.
SAE controlled codes must be set as prescribed by
the SAE, while Manufacturer controlled codes can
be set freely by the manufacturer within the pre-
scribed limits (See DTC chart on page DI±449).

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
(See page BE±2).
(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 diagnostic system is switched from normal mode
to check mode, it erases all DTCs and freeze frame data re-
corded in normal mode. So before switching modes, al-
ways check the DTCs and freeze frame data, and note them
down.
(1) Prepare an OBD II scan tool (complying with SAE
J1978) or TOYOTA hand±held tester.
(2) Connect the OBD II 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 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 freeze frame data and
note them down (For operating instructions, see the
OBD II scan tool's instruction book).
(5) See page DI±449 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
normal mode. For codes on the DTCs chart subject to º2
trip detection logicº, turn the ignition switch off after the
symptoms have been simulated the 1st time. Them repeat
the simulation process again. When the program has 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 high sensing ability to detect mal-
functions. Furthermore, the same diagnostic items which are
detected in 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.

Transaxle in P position.

Air conditioning switched off.
(2) Turn the ignition switch OFF.
(3) Prepare a 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 switch the TOYOTA
hand±held tester ON.
(6) Switch the TOYOTA hand±held tester from Normal
mode to Check mode (Check that the MIL flashes).
(7) Start the engine (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
DTCs, etc..
(9) After simulating the malfunction conditions, use the
TOYOTA hand±held tester diagnosis selector to
check the DTCs and freeze frame data, etc..
HINT:
Take care not to turn the ignition switch OFF, as turning it 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.
