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.

(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.

1. INSPECT EGR SYSTEM
(a) Inspect and clean the filter in the EGR vacuum modulator.
(1) Remove the cap and filter.
(2) Check the filter for contamination or damage.
(3) Using compressed air, clean the filter.
(4) Reinstall the filter and cap.
HINT:
Install the filter with the coarser surface facing the atmospheric
side (outward).
(b) Using a 3±way connector, connect a vacuum gauge to the
hose between the EGR valve and VSV.
(c) Inspect seating of the EGR valve.
Start the engine and check that the engine starts and runs
at idle.
(d) Using SST, connect terminals TE1 and E1 of the DLC1.
SST 09843±18020
(e) Inspect the VSV operation with the cold engine.
(1) The engine coolant temperature should be below
55°C (131°F).
(2) Check that the vacuum gauge indicates zero at
2,500 rpm.
(f) Inspect the operation of the VSV and EGR vacuum modu-
lator with the hot engine.
(1) Warm up the engine to above 60°C (140°F).
(2) Check that the vacuum gauge indicates low vacu-
um at 2,500 rpm.
(3) Disconnect the vacuum hose port R of the EGR vac-
uum modulator and connect port R directly to the in-
take manifold with another hose.
(4) Check that the vacuum gauge indicates high vacu-
um at 2,500 rpm.
