(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. This is used for checking the condition of the clutch and brake.
NOTICE:
Do the test at normal operating fluid temperature 70 to 80 °C (158 to 176 °F).
Be sure to allow 1 minute interval between tests.
Take 3 measurements and take the average value.
(1) Fully apply the parking brake.
(2) Start the engine and check idle speed.
Idle speed (In N position and air conditioner OFF): 700 ± 50 rpm.
(3) Shift the shift lever from N to D position. Using a stop watch, measure the time from when the
lever is shifted until the shock is felt.
Time lag:
N " D Less than 1.2 seconds
(4) In the same manner, measure the time lag for N " R.
Time lag:
N " R Less than 1.5 seconds
Evaluation (If N " D time or N " R time lag is longer than the specified):
ProblemPossible cause
N " D time lag is longer
Line pressure too low
Clutch No. 1 (C
1) worn
One-way clutch No.3 (F
3) not operating properly
N " R time lag is longer

15. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation fluid temperature 70
to 80°C (158 to 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.
This check must be conducted after checking and ad-
justing engine.
Perform under condition that A/C is OFF.
When conducting stall test, do not continue more
than 10 seconds.
(1) Warm up the ATF.
(2) Remove the test plug on the transmission case cen-
ter right side and connect SST.
SST 09992-00095 (09992-00231, 09992-00271)
(3) Fully apply the parking brake and chock the 4
wheels.
(4) Start the engine and check idling speed.
(5) Keep your left foot pressing firmly on the brake ped-
al and shift into D position.
(6) Measure the line pressure when the engine is idling.
(7) Depress the accelerator pedal all the way down.
Quickly read the highest line pressure when engine
speed reaches stall speed.
(8) 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)

16. MANUAL SHIFTING TEST
HINT:
By this test, it can be determined whether the trouble is within
the electrical circuit or is a mechanical problem in the transmis-
sion.
(a) Disconnect the transmission wire.
(b) Inspect the manual driving operation.
Check that the shift and gear positions correspond with
the table below.
While driving, shift through the L, 2, 3, 4 and D positions.
Check that the gear change corresponds to the shift posi-
tion.
Shift PositionGear Position

44th
33rd
21st
L1st
RReverse
PPawl Lock
HINT:
If the gear positions of the L, 2, 3, 4 and D are difficult to distin-
guish, do the following road test.
If any abnormality is found in the above test, the problem is in
the transmission itself.
(c) Connect the transmission wire.
(d) Cancel out DTC.

17. RESET MEMORY
CAUTION:
Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission assy, en-
gine assy or the ECM.
NOTICE:
Hand-held tester only
HINT:
The ECM memorizes the condition that the ECT controls the automatic transmission assy and engine assy
according to those characteristics. Therefore, when the automatic transmission assy, engine assy, or ECM
has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.
Reset procedure is as follows.
(a) Turn the ignition switch off.
(b) Connect the hand-held tester to the DLC3.
(c) Turn the ignition switch to the ON position and push the hand-held tester main switch on.
(d) Select the item ºDIAGNOSIS/ENHANCED OBD IIº.
(e) Perform the reset memory procedure from the ENGINE menu.
CAUTION:
After performing the RESET MEMORY, be sure to perform the ROAD TEST described earlier.
