This test measures the line
pressure when the selector lever is in the D or R position
with the engine idling or stalled. With this test, the
operation status of the transmission components can be
checked.

1.
| warning |
For safety, operators must not
stand in front of and at the rear of the vehicle
during this test.
|
Check the ATF temperature.
- ATF temperature: 50 - 80 ?
- Switches for air conditioner, lamps, and others
shall be OFF.
| note |
Use the M.U.T.-III to measure
the ATF temperature.
|
|
|
|
3.Remove the test plug from
the line pressure take off port (C1).
|
|
4.Install special tools as
shown in the figure and place the meter inside
vehicle.
- Oil pressure gauge <3.0 MPa>
(MD998330)
- Adapter (MD998920)
5.Pull the parking brake lever, and then fully
depress the brake pedal.
6.Start the
engine.
7.
| caution |
- Do not maintain the WOT condition for 5
seconds or longer.
- Perform the measurements for 3 times or
more, and obtain the average value of
the measurements.
- When successively performing the test
under the stall state, only perform the
test after checking that the fluid
temperature is not at 80°C or
more. If the fluid temperature exceeds
80°C, perform the test after
running the engine at around 1,000
r/min for 1 minute or longer and
then cooling the ATF to 80°C or
less.
|
8.Shift the selector lever to D and R, and
measure the idle state line pressure.
| note |
While the measurements are
taken, then engine should be running at idle. A
maximum hydraulic pressure depends on the
driving conditions.

pressure take off port (C1) and install the test
plug.
