The following actions will erase the DTC and freeze frame
data. Operating an OBD II scan tool (complying with SAE

(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 Pub. No. RM654U on page SS±54).
HINT:
O/D Gear Up±shift Prohibition Control (1. Coolant temp. is 50 °C (122 °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 50 °C
(122 °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 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 Pub. No. RM654U on 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 Pub. No. RM654U on 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.

(b) Measure the time lag.
When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag before
the shock can be felt.

7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation fluid temperature 50 ± 80 °C (122 ± 176 °F).
The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
Be careful to prevent SST's hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the transaxle case front left side and connect SST.
(See Pub. No. RM654U on page AX±17 for the location to connect SST)
SST 09992±00095 (09992±00231, 09992±00271)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Connect an OBD II scan tool or hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake pedal and shift into D position.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
(9) In the same manner, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf/cm2, psi)R position kPa (kgf/cm2, psi)
Idling362 ± 422 (3.7 ± 4.3, 53 ± 61)618 ± 794 (6.3 ± 8.1, 90 ± 115)
Stall735 ± 862 (7.5 ± 8.8, 107 ± 125)1,373 ± 1,608 (14.0 ± 16.4, 199 ± 233)
If the measured pressure is not up to the specified value, recheck the throttle cable adjustment and retest.
