2.
PERFORM ACTIVE TEST USING TECHSTREAM (RUNNING TEST)
CAUTION:
This test should always be performed with at least 2 people.
NOTICE:
Perform the test at the normal operating ATF temperature: 50 to 80°C (122 to 176°F).
Perform the test with the A/C turned off.
HINT:
Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be
operated without removing any parts. This non-intrusive functional inspection can be very useful because
intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early
in troubleshooting is one way to save diagnostic time. Data List information can be displayed while
performing Active Tests.
(a) Connect the Techstream to the DLC3.
(b) Clear the DTC
.
(c) Warm up the engine.
(d) Enter the following menus: Powertrain / Engine and ECT / Active Test.
(e) According to the display on the Techstream, perform the Active Test.
HINT:
While driving, the shift position can be forcibly changed with the Techstream.
Comparing the shift position commanded by the Active Test with the actual shift position enables you to
confirm the problem

PERFORM ACTIVE TEST USING TECHSTREAM (SHIFT SOLENOID VALVE SLT)
NOTICE:
Perform the test at the normal operating ATF temperature: 50 to 80°C (122 to 176°F).
Be careful to prevent SST's hose from interfering with the exhaust pipe.
Perform the test with the A/C OFF.

AB60E AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMIS...
(a) Remove the test plug on the transmission case center right
side and connect SST.
SST: 09992-00095
09992-00231
09992-00271
(b) Connect the Techstream to the DLC3.
(c) Start the engine and warm it up.
(d) Measure the line pressure with SST.
(e) Turn the Techstream on.
(f) Enter the following menus: Powertrain / Engine and ECT / Active Test.
(g) According to the display on the Techstream, perform the Active Test.
(h) Measure the line pressure.

HINT:
OFF: Line pressure up (when Active Test
"Activate the Solenoid (SLT)" is performed,
ECM commands SLT solenoid to turn OFF)
ON: No action (normal operation)
[Vehicle Condition]
Vehicle
stopped
Engine
idling
HINT:
*: Activate the Solenoid (SLT) in the Active Test is performed to check the line pressure changes by
connecting SST to the automatic transmission, which is used in the Hydraulic Test
as well. Note that
the pressure values in the Active Test and Hydraulic Test are different.
OK:

OK
The line pressure changes as specified when performing the Active Test.
