ture 70 − 80°C (158 − 176°F) and add as neces-
sary.

(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 O/D direct clutch, forward clutch,
direct clutch, and 1st and reverse brake.
NOTICE:
Do the test at normal operating ATF temperature 50 − 80°C (122 − 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: 750 ± 50 rpm (In N position and A/C OFF)
(3) Shift the shift lever from the N to D position. Using a stop watch, measure the time it takes from
shifting the lever until the shock is felt.
Time lag: N → D Less than 1.2 seconds
In the same way, measure the time lag for N → R.
Time lag: N → R Less than 1.5 seconds
If N → D or N → R time lag is longer than specified:
Evaluation:

(a) Preparation.
(1) Warm up the ATF.
(2) Remove the test plug and connect SST (See page AX−18 for the location to connect SST).

CAUTION:
Perform the test at normal operating ATF temperature 50 − 80°C (122 − 176°F)
The line pressure test should always be carried out in pairs. One should observe the conditions
of wheels or wheel stoppers outside the vehicle while the other is performing the test.
(b) Measure the center differential clutch control pressure.
(1) Start the vehicle and open the accelerator open 50 % or more and check that the center differen-
tial clutch control pressure is in the range from more than 294 kPa (3.0 kgf/cm
2, 42 psi).
(2) Fully close the accelerator and check that the SST registers 9.8 kPa (0.1 kgf/cm
2, 1.4 psi) or less.
CAUTION:
Confirm safety of the road before checking.
Take care to avoid slip when you start the vehicle on a paved road.
Check the pressure at normal driving ATF temperature 50 − 80°C (122 − 176°F).
Reference:
To measure center differential control pressure to be measured with the solenoid opened by applying voltage
to it, refer to the following:
Prepare a sub−assembly for checking as follows:
Prepare a supply connector (Part No. 90980−10629, or 90980−11143)
Connect a harness of 2 − 3 m (6.6 − 9.8 ft) to terminal 1 of the connector.
Place a bulb of 24W in between the harness.
Connect a harness of 2 − 3 m (6.6 − 9.8 ft) to terminal 3 of the connector.
Connect the inspection’s sub−harness assembly to the solenoid connector of the transfer.
Connect terminal 1 of the sub−harness to the battery’s positive (+) terminal, and terminal 3 of the sub−
harness to the battery’s negative (−) terminal.
Measure the center differential control pressure at idling and when performing the stall test (When 1st
gear).

The ECM uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd or O/D
gear). The ECM then compares the actual gear with the shift schedule in the ECM memory to detect mechan-
ical trouble of the shift solenoid valves and valve body.
