INSPECTION PROCEDURE
HINT:
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.
1 Are there any other codes (besides DTC P1411) being output?
YES Go to relevant DTC chart.
NO
Replace EGR valve position sensor.

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 an OBD II scan tool complying
with SAE J1987 or TOYOTA hand±held tester to the
vehicle, 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±16).
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 the codes pre-
scribed by the SAE, while Manufacturer controlled
codes can be set freely by the manufacturer within
the prescribed limits.
(See DTC chart on page DI±401)

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±47).
(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 sys-
tem is switched from normal mode to check mode, it erases
all DTCs and freeze frame data recorded in normal mode.
So before switching modes, always 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 portion of the instru-
ment 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±401 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. Then repeat
the simulation process again. When the program has
DTCs, the DTCs are recorded in the ECM.

(b) Clearance the DTC.
The following actions will erase the DTC and freeze frame
data. Operating an 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.)
4. ROAD TEST
NOTICE:
Perform the test at normal operating ATF temperature 50 ± 80 °C (122 ± 176 °F).
(a) D position test
Shift into the D position and fully depress the accelerator pedal and and check the following points:
(1) Check up±shift operation.
1 " 2, 2 " 3 and 3 " O/D up±shifts take place, at the shift point shown in the automatic shift
schedule (See page SS±54).
HINT:

O/D Gear Up±shift Prohibition Control (1. Coolant temp. is 50 °C (122 °C) or less. 2. If there is a 10
km/h (6 mph) difference between the set cruise control speed and vehicle speed.)

O/D Gear Lock±up Prohibition Control (1. Brake pedal is depressed. 2. Coolant temp. is 50 °C
(122 °C) or less.)
(2) Check for shift shock and slip.
Check for shock and slip at the 1 " 2, 2 " 3 and 3 " O/D up±shifts.
(3) Check for abnormal noises and vibration.
Run at the D position lock±up or O/D gear and check for abnormal noises and vibration.
HINT:
The check for the cause of abnormal noises and vibration must be done very thoroughly as it could also be
due to loss of balance in the differential or torque converter clutch, etc.
(4) Check kick±down operation.
While running in the D position, 2nd, 3rd and O/D gears, check to see that the possible kick±down
vehicle speed limits for 2 " 1, 3 " 2 and O/D " 3 kick±downs conform to those indicated on
the automatic shift schedule (See page SS±54).
(5) Check abnormal shock and slip at kick±down.
(6) Check the lock±up mechanism.

Drive in D position, O/D gear, at a steady speed (lock±up ON) of about 75 km/h (47 mph).

Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
If there is a big jump in engine speed, there is no lock±up.
(b) 2 position test
Shift into the 2 position and fully depress the accelerator pedal and check the following points:
(1) Check up±shift operation.
Check to see that the 1 " 2 up±shift takes place and that the shift point conforms to the automatic
shift schedule (See page SS±54).
HINT:
There is no O/D up±shift and lock±up in the 2 position.
(2) Check engine braking.
While running in the 2 position and 2nd gear, release the accelerator pedal and check the engine
braking effect.
