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.

(b) Clearance the DTC.
The following actions will erase the DTC and freezed
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±shift takes place, at the shift point shown in the automatic shift
schedule (See page SS±56).
HINT:

O/D Gear Up±shift Prohibition Control (1. Coolant temp. is 60 °C (140 °F) 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 60 °C
(140 °F) 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 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±56).
(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 60 km/h (37 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±56).
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.
(3) Check for abnormal noises during acceleration and deceleration, and for shock at up±shift and
down±shift.

(f) Inspect and adjust the shift lever position.
When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator is not aligned with the correct position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures.
(1) Loosen the nut on the shift lever.
(2) Push the control shaft fully rearward.
(3) Return the control shaft lever 2 notches to N posi-
tion.
(4) Set the shift lever to N position.
(5) While holding the shift lever lightly toward the R
position side, tighten the shift lever nut.
Torque: 13 N´m (130 kgf´cm, 9 ft´lbf)
(6) Start the engine and make sure that the vehicle
moves forward when shifting the lever from the N to
D position and reverses when shifting it to the R
position.
(g) Inspect and adjust the park/neutral position.
Check that the engine can be started with the shift lever
only in the N or P position, but not in other positions.
If it is not as stated above, carry out the following adjustment
procedures.
(1) Loosen the park/neutral position switch bolt and set
the shift lever to the N position.
(2) Align the groove and neutral basic line.
(3) Hold in position and tighten the bolt.
Torque: 5.4 N´m (55 kgf´cm, 48 in´lbf)
For continuity inspection of the park/neutral position
switch, see page DI±479.
(h) Check the idle speed.
Idle speed: 700 ± 50 rpm
(In N position and air conditioner OFF)
6. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:

Do the test at normal operating fluid temperature 50 ± 80 °C (122 ± 176 °F).

Do not continuously run this test longer than 5 seconds.

To ensure safety, conduct this test in a wide, clear level area which provides good traction.

The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressed firmly on the brake pedal.
(5) Start the engine.
